Why it matters
Microsoft Defender's AI-agent detection gives defenders native monitoring for autonomous agents that invoke tools, access data, and act on connected systems, an emerging attack surface with limited visibility.
Microsoft documents a public-preview capability in Microsoft Defender XDR that detects and investigates threats to deployed AI agents managed through Microsoft Agent 365. The feature ingests observability data from agents built on Copilot Studio, Microsoft Foundry, and the Agent 365 SDK to raise near-real-time alerts on suspicious or malicious agent behavior and trace root cause and blast radius.
