Secure agentic AI end-to-end
Summary
Agentic AI (AI systems that can take independent actions to accomplish goals) is rapidly spreading through organizations, with 80% of Fortune 500 companies already using agents, but these systems can become security risks if compromised into acting against their owners. Microsoft is addressing this challenge by introducing Agent 365, a control system that gives IT and security teams the ability to observe, control, and protect agents across their organization, along with new security tools in Microsoft Defender, Entra (identity management), and Purview (data governance).
Solution / Mitigation
Agent 365 will be generally available on May 1 and serves as 'the control plane for agents,' providing 'visibility and tools needed to observe, secure, and govern agents at scale.' It includes new capabilities in Microsoft Defender, Entra, and Purview to 'secure agent access, prevent data oversharing, and defend against emerging threats.' Additionally, Security Dashboard for AI (now generally available) provides 'unified visibility into AI-related risk across the organization,' and Entra Internet Access Shadow AI Detection (generally available March 31) 'uses the network layer to identify previously unknown AI applications and surface unmanaged AI usage.'
