Microsoft Security Exposure Management adds Secure Now guidance for agentic AI containment

Microsoft's August 2026 security roundup (published Aug 27, 2026) announced new Secure Now guidance within Microsoft Security Exposure Management focused on containing autonomous agent actions before they expand across an environment — covering agent-initiated action constraints, attack-surface hardening, identity/permission governance, and visibility.

Provides prescriptive, built-in containment recommendations for agentic AI risk directly inside an exposure-management product used broadly across Microsoft 365/Azure security customers, operationalizing 'no implicit authority' principles at scale.

Microsoft Security Exposure Management customers deploying autonomous agents should review and apply the new Secure Now agentic containment recommendations.
