Microsoft Agent 365 is an enterprise-grade AI agent governance and management platform that became generally available on May 1, 2026. It serves as the control plane for organizations to observe, govern, and secure the growing ecosystem of AI agents across their environments. The platform assigns each AI agent its own Microsoft Entra identity with least-privilege permissions, integrates Microsoft Purview for data loss prevention at the agent level, and extends Microsoft Defender for continuous threat detection and runtime protection. Agent 365 provides a centralized agent registry for real-time visibility into all deployed agents — including locally running agents on Windows endpoints (such as OpenClaw, GitHub Copilot CLI, and Claude Code) as well as cloud agents across Azure, AWS Bedrock, and Google Cloud. IT and security teams can discover shadow AI agents, enforce policy-based controls, manage agent lifecycle, and ensure compliance across multicloud environments. The platform is positioned as the foundational governance layer for enterprises scaling from AI pilot programs to production-grade agentic deployments.
