But most organizations are still operating across disparate systems. Identity signals are captured in one place, access policies enforced in another, and response workflows managed separately. That fragmentation slows decision-making, increases operational complexity, and creates gaps cyberattackers can exploit.

Customers are looking for an identity platform that meets their evolving needs. We’re pleased to share that Microsoft has been recognized as a Leader in The Forrester Wave™: Workforce Identity Security Platforms, Q2 2026, receiving the highest scores in both the current offering and strategy categories. We believe this recognition demonstrates the value that the Microsoft Entra product portfolio brings to our customers, which we are always striving to improve. This report also reflects a broader shift in the market. Identity is no longer just a checkpoint in the access flow. It has become the primary way organizations manage risk across environments.

Forrester’s research highlights the need for strong identity foundations, actionable intelligence, and support for emerging AI-powered scenarios. As identity surfaces expand and cyberthreats grow more dynamic, organizations need a model that connects signals, enforces policy consistently, and drives response in real time. Without that continuity, security remains reactive and incomplete.

This is especially important as identity continues to be one of the most targeted attack surfaces, with credential-based attacks still dominating. Securing access requires more than stronger authentication. It requires bringing identity, access, and response into a unified system.

Why this recognition matters now

As AI expands the number of identities and accelerates the pace of change, organizations need approaches that simplify how identity is managed while strengthening how risk is controlled. That means moving beyond disconnected tools toward systems that are integrated by design.

The priorities highlighted by Forrester in their report reflect this reality. They also align with Microsoft’s focus on delivering a comprehensive strategy based on Zero Trust principles, using AI in the flow of work, and extending identity and access controls to AI agents. Forrester noted Microsoft strengths in identity threat detection and response (ITDR), access control, phishing-resistant authentication, and identity verification. These capabilities are essential for organizations to stay ahead of evolving cyberthreats and improve their identity security posture continuously. Microsoft is focused on helping customers reap the benefits of a unified system that extends governance, visibility, and control across all identities.

AI is accelerating identity complexity

AI is reshaping the identity landscape. It is increasing both the number of identities and the speed at which they operate.

In addition to human users, organizations now need to manage AI agents and other non-human identities. These identities require authentication, authorization, lifecycle management, and governance. They operate at machine speed and interact with systems in ways traditional identity models were not designed to handle. At this scale, static policies and disconnected systems fall short. Organizations need continuous enforcement driven by real-time signals.

Treating AI-powered identities as core participants in an identity strategy enables organizations to extend governance, visibility, and control as their environments evolve. This is not an incremental change. It is a structural shift in how identity must be managed.

Evolving your identity and access approach

Identity and access should be an integrated system rather than a collection of tools, for human and non-human identities. An Access Fabric brings together identity signals, access policies, and security workflows into a continuous loop. Signals inform decisions. Decisions trigger enforcement. Enforcement drives response.

This model enables organizations to move beyond static, point-in-time checks to continuous, context-aware access decisions across environments.

With Microsoft Entra, organizations can apply consistent access policies to any identity across Microsoft cloud, on-premises, and third-party applications, helping reduce fragmentation while improving visibility and control.

By bringing signals, policy enforcement, and response together, Microsoft Entra helps organizations move from reactive identity management to continuous risk evaluation and control.

The post What’s new in Microsoft Security: May 2026 appeared first on Microsoft Security Blog.

The AI systems shipping inside enterprises today are fundamentally different from the ones we were building even two years ago, because they have moved well past answering questions and into accessing your email, retrieving records from your CRM, writing and executing code, and taking actions on your behalf across dozens of connected systems. That shift from “generate text” to “do things in the world” changes the safety equation entirely, because an agent that can act can also potentially act in ways nobody intended.

Today Microsoft is open-sourcing two tools designed to help engineers: Microsoft RAMPART, an agent test framework for encoding adversarial and benign scenarios as repeatable tests that can run in CI, making it easy to turn red-team findings and AI incidents into lasting regression coverage; and Clarity, a structured sounding board that helps teams figure out whether they are building the right thing before they write a single line of code.

We built these tools because we believe that AI safety has to become a continuous engineering discipline rather than a periodic checkpoint, and we think the best way to make that happen is to put practical, open tools in the hands of the people doing the building.

Why we are investing in this

1. Helping teams think through the “why,” before the “how” of software building: In the vibe coding era, execution is easy and the harder question is the “why.” The most expensive safety failures we see almost always trace back to design mistakes that nobody questioned early enough, long before any adversary got involved — say, when a product team decided their agent should have access to a tool, or handle a particular user flow, without fully working through what could go wrong. By the time a red team engagement surfaces the issue, the system is largely built, and addressing it means going back to the drawing board. We wanted to give product managers and engineers a way to pressure-test their assumptions at the start of a project, when changing course is cheap and the right conversation can save months of rework.
2. Scaling the lessons of red teaming across the industry. The techniques that uncover vulnerabilities in one agentic product almost always shed light on another. A cross-prompt injection attack that works against one system will often work, with minor variations, against a customer service agent or a coding assistant. But those lessons tend to stay locked inside individual engagement reports. Our goal was to build a system where the lessons of red teaming exercises can be turned into runnable engineering assets.  
3. Making incidents reproducible and mitigations verifiable. If something goes wrong in production AI systems, the team responding needs to do two things quickly: replicate the incident so they understand exactly what happened, and verify that whatever fix they ship actually holds up against variants of the original attack. Both of those tasks are harder than they sound with probabilistic LLMpowered systems, and most teams end up doing them manually in an ad hoc way. We wanted tooling that is purpose-built for exactly this workflow, so that incident response becomes a repeatable engineering process rather than a scramble.

RAMPART: Continuous safety testing for agentic AI

RAMPART is an open-source testing framework that brings red teaming techniques directly into the development workflow. It is built on top of PyRIT, Microsoft’s open automation framework for red teaming generative AI systems so that RAMPART leverages the best in class, out of the box adversarial tests. Where PyRIT is optimized for black-box discovery by security researchers after the system is built, RAMPART is built for engineers as the system is being built.

The developer experience will feel familiar to anyone who has written integration tests. Teams write standard pytest tests that describe scenarios drawn from their threat model. Each test connects to the agent through a thin adapter, orchestrates an interaction, and evaluates observable outcomes. Tests return a clear pass or fail signal and can be gated in CI just like any other integration test. When a new tool or data source is added to the agent, the corresponding safety test can be added in the same pull request.

RAMPART is different from conventional testing in the following ways:

1. Built for prompt injection attacks: RAMPART’s most mature coverage today focuses on cross-prompt injection attacks, scenarios in which an agent retrieves or processes potentially poisoned content from documents, emails, tickets, or other data sources that manipulate its behavior indirectly.  New threat categories can be added incrementally as attack patterns evolve, and the framework’s extension points are all defined as Python protocols, so integration stays lightweight even for complex agent architectures.<
2. Built for probabilistic behavior: Because LLM behavior is probabilistic, RAMPART supports statistical trials. The same test can run multiple times with policies like “this action must be safe in at least 80 percent of runs.” This reflects how agents actually behave in production far more accurately than single-shot validation ever could.
3. Built to reproduce your AI red team findings and AI incidents: RAMPART is designed to work alongside dedicated red teaming, and the two reinforce each other. Findings from a red team engagement can be encoded as RAMPART tests, which means the issue is permanently covered, runs on every change, and never silently regresses. The ownership model is intentionally flipped from the traditional approach: engineers write the tests, engineers run them, and engineers treat failures like any other bug. The framework supplies the attack strategies, adversarial payload generation, and evaluation logic. The test author focuses on expressing expectations about what their agent should and should not do.

Agent safety ultimately comes down to what the agent does, which means evaluators need to look at which tools it invokes, what side effects occur, and whether those actions stay within expected boundaries. RAMPART’s evaluators are designed to inspect all of that. They are composable, so teams can combine them with boolean logic to express nuanced safety conditions rather than relying on a single binary signal.

Clarity: Helping check software engineering assumptions

Where most AI tools are designed to help teams execute faster, Clarity was designed by Microsoft to help them figure out whether they are executing on the right thing in the first place. It asks the kinds of questions that experienced architects, product managers, and safety engineers would ask, the ones that are easy to skip when a team is excited about building something new.

Consider a team that wants to add real-time collaboration to a document editor. Instead of jumping straight to implementation options, Clarity will ask what happens when two people edit the same paragraph at the same time, and whether the team actually needs true real-time collaboration with cursors and presence indicators, or whether “nobody loses their work” is the real requirement. Those two answers can lead to very different architectures with very different failure modes, and getting clarity on that distinction early can save months of rework.

Clarity runs as a desktop app, a web UI, or embedded directly in a coding agent. It guides engineers through structured conversations covering problem clarification, solution exploration, failure analysis, and decision tracking. As the conversation progresses, the results are written to a .clarity-protocol/ directory in the repo as plain, human-readable markdown files that get committed, reviewed in pull requests, and diffed just like source code. They capture the problem statement, the solution rationale, the failure analysis, and the key decisions made along the way.

The failure analysis deserves a closer look, because it goes well beyond what a single reviewer would typically catch. Multiple AI “thinkers” independently examine the system from different angles, including security, human factors, adversarial scenarios, and operational concerns. The team then works through the results together with Clarity, grouping related failures, tracing causal chains, and building management plans.  

Clarity also tracks staleness across these documents, because they form a dependency graph. When a problem statement changes, Clarity knows that the solution description and failure analysis might need revisiting and nudges the team to do so. Important decisions are captured with their criteria, the options considered, and the rationale behind each choice, so that six months later anyone on the team can revisit the full reasoning, including which alternatives were ruled out and why.

The .clarity-protocol/ directory becomes a shared artifact that everyone on the team can see and contribute to, and for stakeholders who need a summary before a review, Clarity can generate a review packet that tells a coherent narrative.

RAMPART and Clarity are part of a broader movement toward spec-driven, engineering-native AI safety. They complement Microsoft’s work on policy-to-measurement systems: Clarity helps teams clarify design intent and capture assumptions; RAMPART gives teams the building blocks to write concrete agent safety testsand keep them running as agents evolve.. Together, these approaches move AI safety from a one-time review to a set of living artifacts that developers can use throughout the lifecycle.

RAMPART and Clarity available now

Both RAMPART and Clarity are available today as open source projects from Microsoft.

KuppingerCole Analysts’ 2026 Emerging AI Security Operations Center (SOC) reflects this shift clearly: the future of security automation is not defined by static rules or isolated workflows, but by intelligence‑driven automation that supports analyst decision‑making across the full security lifecycle. This evolution mirrors what many security leaders already experience day to day, that the limiting factor is no longer alert volume, but human capacity.

Microsoft is excited to be named an Overall Leader, and the Market Leader, in this report, as we see automation as a core component of the future of cybersecurity.

From playbook‑driven SOAR to intelligence‑led automation

Traditional security orchestration, automation, and response (SOAR) solutions were built to automate predictable, repeatable tasks: enrichment steps, ticket creation, notifications, and predefined containment actions. These capabilities remain valuable, but they were designed for an era when incidents followed more deterministic patterns.

This is a critical change. In many SOCs today, analysts still spend significant time:

• Stitching together context across alerts and data sources.
• Manually triaging incidents that turn out to be benign.
• Following repetitive investigation and response steps.

The result is slower response times and analyst burnout—at exactly the moment attackers are moving faster and operating more quietly.

Automation built into the analyst experience

Microsoft has evolved the way these common challenges can be addressed, leveraging machine learning, large language models (LLMs), and agents, including releases such as:

• Automatic attack disruption: An always-on capability that limits lateral attackers and reduces the overall impact of an attack, from associated costs to loss of productivity, leaving security operations teams in complete control of investigating, remediating, and bringing assets back online.
• Phishing triage agent: An agent that runs sophisticated assessments—including semantic evaluation of email content, URL and file inspection, and intent detection—to determine whether a submission is a true phishing threat or a false alarm.
• AI powered incident prioritization: A machine learning prioritization model to surface the incidents that matter most, assigning each incident a priority score from 0–100 and explaining the key factors behind the ranking. 
• Playbook generator: An experience that allows users to create python-code playbooks using natural language for flexible workflow automation.

These capabilities are just the beginning of how we are introducing agents and automation to help users move faster, freeing analysts to focus on higher‑value tasks like proactive hunting and threat analysis.

The next evolution: The agentic SOC

The KuppingerCole report reinforces a broader industry trend, that security platforms must do more than automate pre‑defined workflows. They must support adaptive, intelligence‑driven operations that can respond to novel and fast‑moving threats.

This is where Microsoft is making its next set of investments: agentic security operations.

With innovations such as the Microsoft Sentinel MCP (Model Context Protocol) Server, shared security data and graph context, and deep integration with Microsoft Security Copilot, Sentinel is evolving into a platform where AI agents can:

• Reason across identity, endpoint, cloud, and network signals.
• Summarize incidents and investigations in natural language.
• Assist with decision‑making by correlating weak signals over time.
• Take action—with human oversight—when confidence thresholds are met.

These agents are designed to work alongside analysts, augmenting expertise and dramatically accelerating time to response.

Why this matters for security teams

The direction highlighted by KuppingerCole, and reflected in Microsoft’s roadmap, isn’t about chasing AI for its own sake. It’s about addressing real SOC pain points:

• Scale: Human‑only operations don’t scale with modern attack surfaces.
• Consistency: Automated and agent‑assisted workflows reduce variance and errors.
• Speed: Faster reasoning and response directly reduce attacker dwell time.

By combining automation, rich context, and intelligent agents, Microsoft Sentinel helps SOC teams move from reactive alert handling to proactive, intelligence‑led defense without forcing teams to re‑architect their operations overnight.

Looking ahead

Security automation is no longer a bolt‑on capability. As KuppingerCole’s research makes clear, it is becoming a foundational element of modern security operations. The evolution of SOAR reflects the reality of a shift from static playbooks to adaptive, context‑aware assistance that scales human expertise.

Microsoft is investing accordingly, advancing an AI‑first approach to security analytics that helps SOC teams operate with greater speed, confidence, and resilience as threats continue to evolve. Read the Emerging AI Security Operations Center (SOC) report to learn more.

Choose an ecosystem partner for agent security and governance

AI agents aren’t coming—they’re already in your environment. They show up in places you expect (like Microsoft Copilot, Microsoft Teams, and Microsoft 365) and even more places as technology evolves (a local autonomous personal AI assistant or a new software as a service (SaaS) agent connected to your sensitive data.)

The problem isn’t that agents exist. It’s that they proliferate fast, span apps, endpoints and cloud, and often operate outside the visibility and control of the teams accountable for risk. When an agent can invoke tools, access data, and interact with other agents, any “helpful” workflow can turn into data oversharing, tool misuse, or over-privileged actions in seconds. And as agents become even easier to create and deploy, your attack surface grows with them. 

That’s why end-to-end observability matters: you can’t govern what you can’t see, and you can’t secure what you don’t understand—especially when the number of agents is a moving target. 

Microsoft Agent 365 helps you take control of agent sprawl as your control plane to observe, govern, and secure agents and their interactions—including agents built with Microsoft AI and agents from our ecosystem partners—using the admin and security workflows your teams already run. 

General availability starts today for Agent 365.

Additionally, we’re announcing the previews of new Agent 365 capabilities and integrations to help you scale agent adoption with the right controls in place. 

• Observability, governance, and security for agents operating independently—Agent 365 is expanding to cover agents that operate with their own credentials and permissions.
• Discovery of agents and shadow AI, using capabilities of Microsoft Defender and Microsoft Intune for both local and cloud agents.
• A secured, managed environment for agents to work in Windows 365 for Agents.
• Coverage for a wide ecosystem of SaaS agents, including agents innovated by software development companies (SDCs).
• Support for evaluation, adoption, and usage from Microsoft and ecosystem partners worldwide.

Manage agents with a single control plane, regardless of how or where they work

As organizations move from pilot to adoption, AI agents are being deployed across increasingly diverse use cases. Some act with delegated access, working on behalf of users; others operate with their own credentials and permissions, participating in team workflows or operating behind the scenes. 

With Agent 365, you can observe, govern, and secure AI agents whether they act on behalf of users with delegated access—for example, an agent that helps employees organize their inbox—or agents that operate with their own access and scope of work—such as an agent autonomously triaging support tickets. 

Discover and manage local and cloud-hosted agents 

Users are installing agents like OpenClaw and Claude Code on their devices and adopting SaaS agents built by developers on new and emerging platforms. Many of these local and cloud-hosted agents run unmanaged and outside of traditional governance, as they autonomously execute tasks, modify code, or access confidential information, creating a new wave of shadow AI.  

To help organizations address accelerating agent sprawl and the rise of unmanaged agents, we’re introducing new capabilities as part of Agent 365, Microsoft Defender, and Intune so you can discover shadow agents, and apply appropriate controls, such as blocking unmanaged agents. 

Discover and manage local agents

With Microsoft Defender and Intune, organizations will be able to discover and manage local AI agents running on Windows devices, starting with OpenClaw agents and expanding soon to other widely used agents like GitHub Copilot CLI and Claude Code. Customers enrolled in the Frontier program can see if OpenClaw agents are being used in the organization, which devices they are running on, and use Intune policies to block common ways that OpenClaw runs on the new Shadow AI page in Agent 365 in the Microsoft 365 admin center and in the Intune admin center. Through Agent 365 registry, the inventory of local agents will be available in Defender and Intune so IT, endpoint management, and security teams can get a consistent view of discovered local agents in their environment and take appropriate action.

Starting in June 2026, Microsoft Defender will also provide asset context mapping for each agent including the devices they run on, MCP servers configured for those agents, the identities associated with them, and the cloud resources those identities can reach. This will give security teams the context needed to assess exposure and potential blast radius. They can then investigate agent activity, such as file access and network behavior, using familiar endpoint data, and use those insights to identify misconfigurations and even define custom detections.

Beyond monitoring, organizations will be able to apply policy-based controls to set guardrails for what agents are allowed to do—helping protect both agents and organizations from compromise and misuse—with initial support delivered for OpenClaw through Intune. If a managed agent exhibits malicious behavior patterns, such as attempting to access or exfiltrate sensitive data, Defender will be able to block coding agents in runtime and generate alerts with rich incident context to support investigation and response.  

Context mapping capabilities, policy-based controls, plus runtime blocking and alerts will be available in Agent 365 through Intune and Defender public preview in June 2026. 

Visibility across clouds and AI-builder platforms

As developers are rapidly building agents with Microsoft Foundry, AWS Bedrock, and Google Gemini Enterprise Agent Platform (formerly Google Vertex AI) and deploying cloud agents across multicloud and multi-platform environments, the agent sprawl challenge intensifies. To manage potential security risks or vulnerabilities before they become breaches, security and IT teams need visibility to which cloud agents are running, what models these agents are built on, and what resources they’re accessing.

Today, we are excited to announce the public preview of Agent 365 registry sync with AWS Bedrock and Google Cloud connections, enabling IT teams to automatically discover, inventory, and, soon, perform basic lifecycle governance—for example, start, stop, delete agents—across these platforms.

Manage a wide ecosystem of SaaS agents 

Agent 365 works with prebuilt agents in Microsoft 365 Copilot and Teams, agents built with Microsoft Copilot Studio or Microsoft Foundry for your organization, and agents built by software development companies partnered with Microsoft.

Delivering on our promise of control plane for the broad agent ecosystem, we’re excited to announce ecosystem partner agents fully configured to be managed by Agent 365, including Genspark, Zensai, Egnyte, and Zendesk, and agents built on agent factories, including Kasisto, Kore, and n8n. Organizations can observe, govern, and secure these agents in the Agent 365 control plane, with no integration work by IT or security teams.  

Agent 365 software development company launch partners

Enterprises can easily build AI agents today, but scaling them with trust and governance is where most initiatives stall. With Kore.ai deeply integrated into Microsoft Agent 365, identity, security, and governance are built in from the start—empowering enterprises to move from pilots to AI at scale with confidence.

—– Raj Koneru, Chief Executive Officer of Kore.ai

The Agent 365 developer and ecosystem partners play a critical role in extending agents into line-of-business systems, building vertical and scenario-specific integrations, modernizing legacy automation into agent workflows, extending Copilot experiences with custom agents, and helping customers operationalize agent ecosystems at scale. These Agent 365 enabled agents are then observable, governable, and securable in the Agent 365 control plane, accelerating adoption for your organization.

Secure agents as they work in Windows 365 

While Agent 365 provides the control plane to observe, govern, and secure agent activity across the enterprise, Windows 365 for Agents—now available in public preview (in the United States only)—provides a secured, managed environment where agents can carry out that work. It introduces a new class of Cloud PCs purpose-built for agentic workloads and managed in Intune, allowing agents to run in policy-controlled environments, interact with applications, and operate with the same identity, security, and management controls already used for employees.

Now, with Agent 365, you can also observe and secure agents running on Windows 365 for Agents in Microsoft 365 admin center, understanding which agents are connected to the cloud-powered compute. Together, they enable organizations to move from visibility and governance of agents to confidently running them in production environments. 

Secure agents against internet threats with network controls  

AI agents can operate much faster than human users. Without proper guardrails, they can connect to risky web destinations, interact with unsanctioned AI services, handle sensitive files unsafely, or be manipulated through malicious prompt-based attacks. These risks are harder to manage when security teams lack consistent visibility and controls for agent traffic to internet, SaaS, and AI services. 

To give security teams a consistent way to inspect agent traffic at the network layer, in general availability today, Agent 365 extends Microsoft Entra network controls to Microsoft Copilot Studio agents and agents running on user endpoint devices, including local agents such as OpenClaw. These controls can help identify unsanctioned AI usage, restrict connections to only approved web destinations, filter risky file movement, and help block malicious prompt-based attacks before they lead to harmful actions. 

Confidently scale and govern AI agents while maintaining security and control 

Agent 365 extends even further beyond Microsoft platforms to discover, observe, govern, and secure local, SaaS, and cloud agents across your agentic AI ecosystem. Each of today’s announcements build upon Agent 365 capabilities we shared in March 2026 as well as detailed feedback of customers using the Frontier program, developers integrating with the platform, and partners testing Agent 365 capabilities. 

With Agent 365, we can scale and govern AI agents with confidence, while maintaining enterprise grade security and control. Agent 365 enables organizations to move beyond experimentation, driving tangible business value and innovation through trusted AI adoption. By providing a robust and integrated platform, Agent 365 empowers teams to confidently embrace AI and accelerate transformation across the enterprise.

—Yuji Shono, Head of the Global AI Office, NTT DATA Group Corporation, a global infrastructure, networking, and IT services provider.

As organizations begin to adopt Agent 365 at scale, we’ve collaborated with strategic partners to create targeted services to help customers onboard, tackle governance challenges and realize the platform’s full value.

Partner services offered today include expertise and guidance for:

At Microsoft, security innovations are purpose-built to help every organization protect end-to-end with the speed and scale of AI. Our vision is simple: security should be ambient and autonomous, just like the AI it protects.

In a world where AI agents can act autonomously to take action, access data, and interact across systems, every organization should have the confidence that their security posture can scale and keep pace with their AI investments. Microsoft is focused on helping organizations gain visibility into what their agents are doing, governance over what they’re allowed to do, and protection against emerging threats. With an AI-first, end-to-end security platform grounded in Zero Trust for AI, fueled by more than 100 trillion daily threat signals¹, and shaped by the Secure Future Initiative, security and IT teams can harden their security posture with protection that is continuous, intelligent, and built for the agentic era.

In the Loop is a new series from Microsoft Security that delivers timely news and updates to the global security community. Today’s edition spotlights the latest capabilities designed to help security and IT teams secure their AI agents, secure their foundations, and defend against threats in real time with the powerful combination of agents and experts.

The post What’s new, updated, or recently released in Microsoft Security appeared first on Microsoft Security Blog.

Recent advances in AI model capabilities are changing how vulnerabilities are discovered and exploited. AI models can autonomously discover weaknesses, chain multiple lower-severity issues into working end-to-end exploits, and produce working proof-of-concept code. This significantly compresses the window between vulnerability discovery and exploitation.

These changes require organizations to rethink exposure, response, and risk. However, the same capabilities that can give attackers an advantage also create a unique opportunity for defenders. When applied correctly, they can accelerate vulnerability discovery, improve detection engineering, and reduce time to mitigation. We look forward to working together as an industry to use these AI model capabilities as part of enterprise-grade solutions to tilt the balance in favor of defenders.

Partnering with leading model providers

Security has been and remains the top priority at Microsoft. Over the last two years, through our Secure Future Initiative (SFI), we have strengthened our security foundations for this age of AI, in part by using AI to accelerate vulnerability discovery and remediation and help defend against threats. We have also invested in fundamental AI for security research, including the development of open-source industry benchmarks that can be used to evaluate whether models are ready for real-world security work.

As we move forward, we are accelerating this work and partnering with the industry to use leading models, paired with our platforms and expertise, to turn AI-driven discovery into protection at scale.

Through Project Glasswing, Microsoft is working closely with Anthropic and industry partners to test Claude Mythos Preview, identify and mitigate vulnerabilities earlier, and coordinate defensive response. We evaluated Mythos using CTI-REALM, our open-source benchmark for real-world detection engineering tasks, and the results showed substantial improvements relative to prior models.

Microsoft is also evaluating other models. As part of our overall security approach, we continuously evaluate models from multiple providers as they are made available and integrate them into our enterprise-grade security platform. This multi-model approach is intentional as no single model defines our strategy.

Taking action in three fundamental areas

Defenders need to move faster to keep pace with AI-driven threats. We are focusing on three areas to help customers reduce risk and improve resilience.

1. AI-led vulnerability discovery and mitigations to stay current on software

We plan to incorporate advanced AI models, like Claude Mythos Preview, directly into our Security Development Lifecycle (SDL) to identify vulnerabilities and develop mitigations and updates. This allows us to discover more issues more quickly across a broader surface area than previous methods and address them earlier in the lifecycle.

AI-assisted discoveries are handled through our existing Microsoft Security Response Center (MSRC) processes, including Update Tuesday—our predictable and systematic way of distributing updates to customers—and out-of-band updates, where appropriate. Customers using Microsoft platform as a service (PaaS) and software as a service (SaaS) cloud services do not need to take any action; mitigations and updates are applied automatically. For customers who deploy Microsoft products on their own infrastructure, whether on-premises or self-hosted, staying current on all security updates is now not only the best practice; it is a fundamental requirement for staying secure against AI exposure.

We will deploy detections to Microsoft Defender, our threat protection solution, when updates are released and share details through the Microsoft Active Protections Program (MAPP) partners to help mitigate risk. We are also using advanced AI models to proactively scan select open-source codebases. Identified issues will be addressed through coordinated vulnerability disclosure.

2. AI-ready posture to reduce exposure

Patching, while critical, is not sufficient on its own. We have identified the five dimensions where autonomous AI driven attacks gain disproportionate advantage—patching, open-source software, customer source code, internet-facing assets, and baseline security hygiene.

For each dimension, Microsoft Security Exposure Management provides guidance and capabilities that customers can use to:

• Assess their current state.
• Understand prioritized actions to reduce risk.
• Evaluate “what-if” scenarios before making changes.
• Apply automation to remediate issues at scale.

These capabilities include tools like Microsoft Defender External Attack Surface Management (EASM) for continuous discovery of internet-facing assets, GitHub Advanced Security with CodeQL, Copilot Autofix for open-source and first-party code, and Microsoft Baseline Security Mode (BSM) to apply foundational controls across Exchange, Microsoft Teams, SharePoint, OneDrive, Office, and Microsoft Entra—with impact simulation before enforcement.

Others in the industry have shared guidance and rightly emphasized the importance of continuous asset discovery and posture management. We are delivering an integrated experience through a new Microsoft Security Exposure Management blade—Secure Now—that combines guidance with the ability to act, so customers proactively reduce their exposure. Secure Now is available today at https://security.microsoft.com/securenow

3. AI-powered solutions to defend at scale

Beyond plans to use advanced AI models directly into our Security Development Lifecycle (SDL), we are separately building new solutions to help customers leverage advanced AI models to improve their security at enterprise scale.

• Rapidly deployed Defender detections developed for AI-discovered vulnerabilities, sim-shipping with corresponding updates to help mitigate risk immediately.
• We have learned through our own testing that model capability to discover potential vulnerabilities is only the beginning. Organizations must also be able to use AI to validate and prioritize based on exploitability and impact, and build the fix. To help we plan to productize a new multi-model AI-driven scanning harness developed internally and make it available to customers to streamline their experience and deliver outcomes more quickly. This solution is expected to be available in preview in June 2026.

Our goal is to ensure findings are actionable. While models are powerful on their own, without prioritization and context, large volumes of results can overwhelm development teams. These new solutions are designed to pair model output with the context and security solutions needed for enterprises to drive security effectiveness at scale.

Get started today

Customers can get started now by reviewing the guidance at https://security.microsoft.com/securenow. Any customer with a Microsoft Entra ID will be able to access the guidance. In addition, Microsoft Security customers will have access to capabilities that enable them to assess their exposure and take action.

We have also mobilized our Customer Success organization to support customers in implementing this guidance.

What’s ahead

This work is ongoing. We will continue to share updates as testing progresses, new models emerge, and new guidance and solutions become available. The threat landscape will continue to evolve, but so will our defenses—and we are committed to ensuring that our customers have the tools, guidance, and partnership they need to stay ahead.

Security is a team sport. The organizations that act on this shift—by staying current on patches, reducing exposure, and leveraging AI-powered security solutions—will be significantly harder to compromise than those that do not. The time to act is now and we look forward to partnering with the industry to build a safer world for all.

The post AI-powered defense for an AI-accelerated threat landscape appeared first on Microsoft Security Blog.

The challenge isn’t just scale, it’s fragmentation. From our latest Secure Access report, research shows that 32% of organizations say their access management solutions are duplicative, and 40% say they have too many different vendors. That fragmentation for security vendors makes it harder to maintain consistent access controls and correlate risk across identities. When risk is distributed across dozens of disconnected accounts and permissions, visibility fragments and blind spots emerge—creating ideal conditions for cyberattackers to move laterally without detection. Securing identity in this reality requires more than incremental improvements. It calls for a shift from fragmented controls to an integrated, end-to-end approach that treats identity as a shared control plane that is informed by a continuous, foundational security signal.

Why fragmentation fails—and what must replace it

With the traditional model of identity security—built on siloed directories, disconnected access policies, and bolt-on threat detection—cyberattackers don’t have to break defenses, they just move between them. Permissions go uncorrelated, access policies drift as environments evolve, and lateral movement hides in the gaps.

For defenders, this creates a dangerous imbalance. Identity signals flood the security operations center (SOC) without the context to act, while identity teams enforce access without visibility into active cyberthreats. Risk accumulates across systems, but responsibility—and insight—remains fragmented.

Fixing this doesn’t require more alerts or point solutions. It requires an integrated fabric that brings together all of the identities, access, and signals.

A modern identity security solution must unify three critical layers:

• The identity infrastructure: The systems and services that underpin every access decision. This includes the identity provider, authentication services, single sign-on (SSO), user and group management, and the systems that establish and maintain trust across the enterprise. Without this foundation, there is no authoritative source of truth for who an identity is, what it can access, or how it should be governed. It’s the layer many security vendors lack—and the one Microsoft delivers at global scale.
• The identity control plane: Where privileged identity management and access decisions are enforced in real time, based on dynamic risk signals, behavioral context, and policy intent. This is where identity and security converge to adapt access as conditions change, powering real-time response to identity threats.
• End-to-end identity threat protection: Before a cyberattack, it proactively reduces posture risk by eliminating excessive access and closing identity exposure gaps. When threats emerge, it detects identity misuse in real time, surfaces lateral movement, and drives rapid containment—connecting integrated signals and response across the full attack lifecycle.

When these layers operate in isolation, risk is missed. When they operate as one, identity becomes a powerful security signal—enabling earlier detection, smarter decisions, and faster response.

Redefining identity security for real-time defense

Microsoft is delivering a new standard for identity security solution—one that unifies identity infrastructure, access control, and threat response into a single, real-time platform built for speed, precision, and autonomy.

We start with the identity infrastructure: the foundational identity layer powered by Microsoft Entra. As one of the most widely adopted identity platforms in the world with billions of authentications managed daily, it provides resilient SSO, user and group management, and trust establishment at global scale—a layer many security vendors simply don’t have access to.

We collapse identity sprawl, correlating related accounts across cloud and on-premises into a single identity view, so risk assessment is no longer scattered across disconnected systems. This gives security teams a real‑time understanding of what an identity and its correlated accounts can access, not just who it is—allowing them to spot dangerous access paths early, limit impact, and disrupt lateral movement before attackers turn access into impact. Likewise, it gives identity teams visibility into whether a user flagged as a high risk was just a one-off or if its associated with other accounts, informing what access decisions to make.

On top of that foundation is a real-time identity control plane designed for how attacks actually unfold. Microsoft Entra Conditional Access continuously evaluates risk as access is used, not just when it’s granted—tracking signals from identity, device, network, and broader threat intelligence throughout the session. As conditions change, access adapts in real time, helping identity teams limit exposure and prevent risky access while giving security teams the ability to interrupt attack paths while activity is still in motion. This is adaptive access driven by connected intelligence—not static policy.

And when risk turns into a threat, we act—automatically and inline, which results in a faster response. Microsoft’s threat protection is differentiated by automatic attack disruption: a capability that intervenes mid-attack to isolate compromised assets by terminating user sessions, revoking access, and applying just-in-time hardening to stop lateral movement and privilege escalation. It’s not just detection—it’s defense in motion.

To accelerate response, we’ve extended Microsoft Security Copilot’s triage agent to identity. It uses AI to filter noise, surface high-confidence alerts, and guide analysts with clear, explainable insights—reducing time to action and analyst fatigue.

This end-to-end approach shifts identity from an expanding source of exposure into a strategic advantage. Instead of reacting after access has already been abused, it helps ensure that risk is evaluated continuously, access decisions are made in real-time, and organizations can defend more effectively as attack paths emerge to stop identity‑based attacks before they escalate into business impact.

Innovation that moves the industry forward

At RSAC 2026, we announced a set of innovations in identity security that are designed to help organizations move from fragmented awareness to confident, identity-centric protection:

• The new identity security dashboard in Microsoft Defender doesn’t just summarize alerts, it reveals where identity risk actually concentrates across human and nonhuman identities, account types, and providers. Instead of hopping between consoles, teams can immediately see which access paths matter most, where blast radius is largest, and where action will have the greatest impact.
• A new unified identity risk score correlates together more than 100 trillion signals across Microsoft Security including identity behavior, access risk, and threat signals into a single, actionable view of risk. This allows teams to move directly from understanding exposure to enforcing protection—applying controls at the point of access, natively through risk-based Conditional Access policies.
• Adaptive risk remediation helps identity and security teams contain modern cyberattacks more efficiently while maintaining strong protection. When risk is detected, users easily regain access and Microsoft Entra ID Protection adapts risk remediation based on the type of cyberthreat and the credentials used. This reduces reliance on help desk processes and lowers manual response effort.
• Automatic attack disruption fundamentally changes the outcome of identity-based attacks. Instead of detecting suspicious behavior and waiting for the security teams to respond, it intervenes while cyberattacks are in progress—terminating sessions, revoking access, and applying just-in-time hardening to shut down cyberattacker movement before lateral spread or privilege escalation can occur.
• Security Copilot’s triage agent now extends to identity. Using AI to collapse signal overload into clear, recommended action, the agent surfaces high confidence threats, explaining why they matter, and guides analysts to the right response while attacks are still unfolding. The result is faster containment with far less analyst fatigue.
• Expanded coverage across the modern identity fabric, including deeper visibility into non-human identities and new integrations with third-party platforms like SailPoint and CyberArk—providing protection that spans the full ecosystem, not just first-party assets.
• A new coverage and maturity view helps organizations assess their current identity security posture, identify gaps, and prioritize next steps—transforming identity protection from a static checklist into a dynamic, guided journey.

These innovations are deeply integrated, continuously reinforced, and designed to work together—enabling security and identity teams to operate from a shared source of truth, with shared context, and shared urgency. Read more about redefining identity security for the modern enterprise.

They are designed to help organizations shift from reactive identity management to proactive identity defense—and from fragmented tools to a unified platform built for real-time security across human, non-human, and agentic identities.

The post Identity security is the new pressure point for modern cyberattacks appeared first on Microsoft Security Blog.

At the same time, this innovation is happening against a sea change in AI-powered attacks where agents can become “double agents.” And chief information officers (CIOs), chief information security officers (CISOs), and security decision makers are grappling with the resulting security implications: How do they observe, govern, and secure agents? How do they secure their foundations in this new era? How can they use agentic AI to protect their organization and detect and respond to traditional and emerging threats?

The answer starts with trust, and security has always been the root of trust. In this agentic era, security must be woven into, and around, every layer of the AI estate. It must be ambient and autonomous, just like the AI it protects. This is our vision for security as the core primitive of the AI stack.

At RSAC 2026, we are delivering on that vision with new purpose-built capabilities designed to help organizations secure agents, secure their foundations, and defend using agents and experts. Fueled by more than 100 trillion daily signals, Microsoft Security helps protect 1.6 million customers, one billion identities, and 24 billion Copilot interactions.² Read on to learn how we can help you secure agentic AI.

Secure agents

Earlier this month, we announced that Agent 365 will be generally available on May 1. Agent 365—the control plane for agents—gives IT, security, and business teams the visibility and tools they need to observe, secure, and govern agents at scale using the infrastructure you already have and trust. It includes new Microsoft Defender, Entra, and Purview capabilities to help you secure agent access, prevent data oversharing, and defend against emerging threats.

Agent 365 is included in Microsoft 365 E7: The Frontier Suite along with Microsoft 365 Copilot, Microsoft Entra Suite, and Microsoft 365 E5, which includes many of the advanced Microsoft Security capabilities below to deliver comprehensive protection for your organization.

Secure your foundations

Along with securing agents, we also need to think of securing AI comprehensively. To truly secure agentic AI, we must secure foundations—the systems that agentic AI is built and runs on and the people who are developing and using AI. At RSAC 2026, we are introducing new capabilities to help you gain visibility into risks across your enterprise, secure identities with continuous adaptive access, safeguard sensitive data across AI workflows, and defend against threats at the speed and scale of AI.

Gain visibility into risks across your enterprise

As AI adoption accelerates, so does the need for comprehensive and continuous visibility into AI risks across your environment—from agents to AI apps and services. We are addressing this challenge with new capabilities that give you insight into risks across your enterprise so you know where AI is showing up, how it is being used, and where your exposure to risk may be growing. New capabilities include:

• Security Dashboard for AI provides CISOs and security teams with unified visibility into AI-related risk across the organization. Now generally available.
• Entra Internet Access Shadow AI Detection uses the network layer to identify previously unknown AI applications and surface unmanaged AI usage that might otherwise go undetected. Generally available March 31.

Now available in preview.

Safeguard sensitive data across AI workflows

With AI embedded in everyday work, sensitive data increasingly moves through prompts, responses, and grounding flows—often faster than policies can keep up. Security teams need visibility into how AI interacts with data as well as the ability to stop data oversharing and data leakage. Microsoft brings data security directly into the AI control plane, giving organizations clear insight into risk, real-time enforcement at the point of use, and the confidence to enable AI responsibly across the enterprise. New Microsoft Purview capabilities include:

• Expanded Purview data loss prevention for Microsoft 365 Copilot helps block sensitive information such as PII, credit card numbers, and custom data types in prompts from being processed or used for web grounding. Generally available March 31.

• Defender for Cloud posture management adds broader coverage and supports Amazon Web Services and Google Cloud Platform, delivering security recommendations and compliance insights for newly discovered resources. Available in preview in April.
• Defender predictive shielding dynamically adjusts identity and access policies during active attacks, reducing exposure and limiting impact. Now available in preview.

Defend with agents and experts

To defend in the agentic age, we need agentic defense. This means having an agentic defense platform and security agents embedded directly into the flow of work, augmented by deep human expertise and comprehensive security services when you need them.

Agents built into the flow of security work

Security teams move fastest with targeted help where and when work is happening. As alerts surface and investigations unfold across identities, data, endpoints, and cloud workloads, AI-powered assistance needs to operate alongside defenders. With Security Copilot now included in Microsoft 365 E5 and E7, we are empowering defenders with agents embedded directly into daily security and IT operations that help accelerate response and reduce manual effort so they can focus on what matters most.

New agents available now include:

• Security Analyst Agent in Microsoft Defender helps accelerate threat investigations by providing contextual analysis and guided workflows. Available in preview March 26.

• Sentinel custom graphs powered by Microsoft Fabric enable views unique to your organization of relationships across your environment. Now available in preview.
• Sentinel model context protocol (MCP) entity analyzer helps automate faster with natural language and harnesses the flexibility of code to accelerate responses. Generally available in April.

Strengthen with experts

Even the most mature security organizations face moments that call for deeper partnership—a sophisticated attack, a complex investigation, a situation where seasoned expertise alongside your team makes all the difference. The Microsoft Defender Experts Suite brings together expert-led services—technical advisory, managed extended detection and response (MXDR), and end-to-end proactive and reactive incident response—to help you defend against advanced cyber threats, build long-term resilience, and modernize security operations with confidence.

Apply Zero Trust for AI

Zero Trust has always been built on three principles: verify explicitly, use least privilege, and assume breach. As AI becomes embedded across your entire environment—from the models you build on, to the data they consume, to the agents that act on your behalf—applying those principles has never been more critical. At RSAC 2026, we’re extending our Zero Trust architecture, the full AI lifecycle—from data ingestion and model training to deployment agent behavior. And we’re making it actionable with an updated Zero Trust for AI reference architecture, workshop, assessment tool, and new patterns and practices articles to help you improve your security posture.

²Microsoft Fiscal Year 2026 First Quarter Earnings Conference Call and Microsoft Fiscal Year 2026 Second Quarter Earnings Conference Call

The post Secure agentic AI end-to-end appeared first on Microsoft Security Blog.

It’s the right question, and it’s the one we’ve been working to answer by updating the tools and guidance you already rely on. We’re announcing Microsoft’s approach to Zero Trust for AI (ZT4AI). Zero Trust for AI extends proven Zero Trust principles to the full AI lifecycle—from data ingestion and model training to deployment and agent behavior. Today, we’re releasing a new set of tools and guidance to help you move forward with confidence:

• A new AI pillar in the Zero Trust Workshop.
• Updated Data and Networking pillars in the Zero Trust Assessment tool.
• A new Zero Trust reference architecture for AI.
• Practical patterns and practices for securing AI at scale.

Here’s what’s new and how to use it.

Why Zero Trust principles must extend to AI

AI systems don’t fit neatly into traditional security models. They introduce new trust boundaries—between users and agents, models and data, and humans and automated decision-making. As organizations adopt autonomous and semi-autonomous AI agents, a new class of risk emerges: agents that are overprivileged, manipulated, or misaligned can act like “double agents,” working against the very outcomes they were built to support.

By applying three foundational principles of Zero Trust to AI:

• Verify explicitly—Continuously evaluate the identity and behavior of AI agents, workloads, and users.
• Apply least privilege—Restrict access to models, prompts, plugins, and data sources to only what’s needed.
• Assume breach—Design AI systems to be resilient to prompt injection, data poisoning, and lateral movement.

These aren’t new principles. What’s new is how we apply them systematically to AI environments.

A unified journey: Strategy → assessment → implementation

The most common challenge we hear from security leaders and practitioners is a lack of a clear, structured path from knowing what to do to doing it. That’s what Microsoft’s approach to Zero Trust for AI is designed to solve—to help you get to next steps and actions, quickly.

Zero Trust Workshop—now with an AI pillar

Building on last year’s announcement, the Zero Trust Workshop has been updated with a dedicated AI pillar, now covering 700 security controls across 116 logical groups and 33 functional swim lanes. It is scenario-based and prescriptive, designed to move teams from assessment to execution with clarity and speed.

The workshop helps organizations:

• Align security, IT, and business stakeholders on shared outcomes.
• Apply Zero Trust principles across all pillars, including AI.
• Explore real-world AI scenarios and the specific risks they introduce.
• Identify cross-product integrations that break down silos and drive measurable progress.

The new AI pillar specifically evaluates how organizations secure AI access and agent identities, protect sensitive data used by and generated through AI, monitor AI usage and behavior across the enterprise, and govern AI responsibly in alignment with risk and compliance objectives.

Zero Trust Assessment—expanded to Data and Networking

As AI agents become more capable, the stakes around data and network security have never been higher. Agents that are insufficiently governed can expose sensitive data, act on malicious prompts, or leak information in ways that are difficult to detect and costly to remediate. Data classification, labeling, governance, and loss prevention are essential controls. So are network-layer defenses that inspect agent behavior, block prompt injections, and prevent unauthorized data exposure.

Yet, manually evaluating security configurations across identity, endpoints, data, and network controls is time consuming and error prone. That is why we built the Zero Trust Assessment to automate it. The Zero Trust Assessment evaluates hundreds of controls aligned to Zero Trust principles, informed by learnings from Microsoft’s Secure Future Initiative (SFI). Today, we are adding Data and Network as new pillars alongside the existing Identity and Devices coverage.

Zero Trust Assessment tests are derived from trusted industry sources including:

• Industry standards such as the National Institute of Standards and Technology (NIST), the Cybersecurity and Infrastructure Security Agency (CISA), and the Center for Internet Security (CIS).
• Microsoft’s own learnings from SFI.
• Real-world customer insights from thousands of security implementations.

And we are not stopping here. A Zero Trust Assessment for AI pillar is currently in development and will be available in summer 2026, extending automated evaluation to AI-specific scenarios and controls.

Overall, the redesigned experience delivers:

• Clearer insights—Simplified views that help teams quickly identify strengths, gaps, and next steps.
• Deep(er) alignment with the Workshop—Assessment insights directly inform workshop discussions, exercises, and deployment paths.
• Actionable, prioritized recommendations—Concrete implementation steps mapped to maturity levels, so you can sequence improvements over time.

Zero Trust for AI reference architecture

Our new Zero Trust for AI reference architecture (extends our existing Zero Trust reference architecture) shows how policy-driven access controls, continuous verification, monitoring, and governance work together to secure AI systems, while increasing resilience when incidents occur.

The architecture gives security, IT, and engineering teams a shared mental model by clarifying where controls apply, how trust boundaries shift with AI, and why defense-in-depth remains essential for agentic workloads.

Practical patterns and practices for AI security

Knowing what to do is one thing. Knowing how to operationalize it at scale is another. Our patterns and practices provide repeatable, proven approaches to the most complex AI security challenges, much like software design patterns offer reusable solutions to common engineering problems.
