Defend Against Threats - Microsoft Defender XDR | Microsoft Learn
Prepare your security operations for AI by connecting threat detection, investigation, and response in Microsoft Defender.
Security imperative: Get ready for AI
Defending against threats to get ready for AI starts with your existing security operations: bring signals, investigations, and response together, expand visibility across Microsoft and non-Microsoft sources, and automate repeatable work.
Job to be done: Defend against threats
That foundation is what lets human defenders and AI agents investigate and respond together, while helping the organization keep pace with AI-accelerated attacks. Defender ISOC supports this by unifying SIEM and XDR in one operational experience built on shared data, analytics, threat intelligence, and workflows.
