TL;DR: Agentic AI security requires authenticating, authorising, and auditing autonomous agents as first-class identities, because non-human identities already outnumber humans by about 50:1 and 80% of IT leaders report agents acting outside expected behaviour, according to Strata Identity and cited research. Existing IAM models break when agents act at machine speed across clouds and delegate work without stable human oversight, making runtime governance mandatory.
Editorial analysis by NHI Mgmt Group, based on content published by Strata Identity: “Agentic AI security: 8 strategies in 2026”.
Key questions
Q: What breaks when autonomous agents are governed like human users?
A: Session-based IAM breaks first, because autonomous agents can make and execute decisions between review points.
Q: Why does agentic AI increase access risk in enterprise identity programs?
A: Agentic AI increases risk because one agent may move across multiple services to complete a single task.
Q: How do security teams know whether managed identities are working for agents?
A: Managed identities are working when there are no embedded secrets in code or config, each agent has a distinct identity, and privileges map cleanly to a small number of functions.
Practitioner guidance
- Define agents as first-class identities Inventory AI agents separately from users and service accounts, then assign each one an owner, a purpose, and a revocation path.
- Shift access control to runtime Apply policy decisions at execution time, not just at session start, so an agent cannot continue after context changes or task boundaries shift.
- Use just-in-time authority for agent tasks Issue the minimum privilege needed for a single task and expire it when the task closes.
Bottom line: Agentic AI changes identity governance because runtime decisions now happen inside the access window, not after it.

Identity review cadences assume privilege outlives the act of use. That assumption was built for humans and long-lived workloads, not for autonomous actors that can acquire and release access within a single execution path. Once the actor is agentic, the review window collapses into runtime, and post-hoc certification no longer describes the control problem. Practitioners must rethink governance around actuation time, not review time.
A few things that frame the scale:
- NHIs outnumber human identities by 25x to 50x in modern enterprises, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: What should teams do immediately when an AI agent behaves unpredictably?
A: Suspend the agent's high-risk access, preserve the prompt and tool-call trail, and review the inputs that may have redirected its behaviour. Containment should happen before the session continues, because the same trust failure can propagate through every subsequent action.
