Microsoft Agent 365 became generally available for the Commercial segment on May 1, 2026, positioned as the control plane for AI agents across the enterprise regardless of where those agents were built or acquired. 

Most organizations are entering this era without a defined governance or security model. The pattern is familiar: 

  • Agents proliferating across business units 
  • No central inventory 
  • Unclear ownership and approval 
  • No lifecycle controls 
  • No runtime monitoring 
  • No visibility into what data agents are touching or what actions they are taking 

This accelerator gives leadership the answers they need before agent volume grows.

The questions on every CISO and CIO’s desk:

  • Which AI agents and Copilots exist across our environment today, and how will Microsoft Agent 365 surface them? 
  • Who owns each agent, who sponsored it, who approved it, and who is accountable when something goes wrong? 
  • How will we extend identity, Conditional Access, and lifecycle controls to agent identities under Microsoft Entra Agent ID? 
  • How will we detect, block, investigate, and hunt suspicious AI agent behaviour using Microsoft Defender XDR? 
  • What governance and security operating model should we adopt before agent volume grows? 
  • What is the right sequence of decisions to make agent adoption safe and defensible?
