Zero Trust for AI Agents: What to Verify When There Is No Session
The agent that worries you is authorized. It holds a service account you provisioned, calls tools you approved, and reaches destinations someone signed off on. Zero trust asks two questions at every decision point, who is this and what are they allowed to do, and an agent redirected by trusted input answers both correctly every time. For a person those questions fire at a session boundary, where context gets re-checked. An agent on Kubernetes has no such boundary.
