Give agents separate identities and make changing risk reduce their authority
Source: Microsoft Security
Microsoft's October 19 announcement extends Project Perception with Guardian Agents and describes Dynamic Permissions, Dynamic Agent Risk, and Dynamic Conditional Access. Its proposed controls assign agents distinct identities, limit authority to a task, and adjust access when behavior or context raises risk. Project Perception remains an invitation-only Limited Public Preview; the announcement is a design and availability signal, not proof that these controls protect every deployed agent today.
Why this matters: Inventory agents and owners, then test a single consequential workflow. Check what the agent can read and change, whether its access expires, and which actions need verified human approval. Simulate an off-task request or untrusted instruction and confirm that the enforcement layer can block writes, narrow access, or stop execution while preserving logs. Verify the actual preview eligibility and product coverage before planning a rollout.
