Holistic protection for your email and collaboration tools
Email remains the number one entry point for cyberattacks. Help ensure that email-based cyberattacks—including phishing via malicious links or QR codes, business email compromise (BEC), and malware—don’t reach your users.
Remote work has fostered the adoption of modern collaboration tools and opened new vulnerabilities for cybercriminals. Help ensure safe collaboration across Microsoft Teams, SharePoint, and OneDrive—with inline protection against malicious URLs, real-time detonation of attachments and links, and other features. Give your security team full visibility into cyberthreats with alerts and data across Microsoft collaboration tools.
As adversaries improve their techniques through the use of AI, it’s critical that your defense does the same. Help protect your business from the most sophisticated cyberthreats. Microsoft uses language models with sentiment analysis to provide AI-powered email and collaboration security.
On average, cyberattacks move laterally in 72 minutes, making manual responses insufficient. Use automated capabilities with extended detection and response (XDR) to disrupt in-progress attacks. XDR technology analyzes the attacker’s intent, identifies compromised assets, and contains cyberthreats in near-real time, minimizing the impact of attacks—such as business email compromise (BEC)—on your organization.
