TL;DR: Agentic AI systems decompose tasks and call tools at runtime, so identity scope, ownership, and revocation now determine blast radius more than authentication alone, according to Akto and joint Five Eyes guidance. Existing IAM models were built for predictable service accounts, not identities whose access can expand, persist, and be misused mid-session.
Editorial analysis by NHI Mgmt Group, based on content published by Akto: “Governing AI Agent Identities: An Identity Maturity Model for AI Agents”.
Key questions
Q: What breaks when AI agents use broad role inheritance?
A: Broad role inheritance creates immediate over-privilege.
Q: Why do autonomous AI systems change the way IAM teams think about least privilege?
A: Least privilege becomes harder to define when intent is not fixed at provisioning time.
Q: How do security teams know if agent governance is actually working?
A: It is working only if the team can answer three questions quickly for any agent: what it can reach, what it did recently, and whether that behaviour matches intent.
Practitioner guidance
- Define a unique identity per agent Never let an agent share a credential with another agent or a human administrator.
- Record the owner and purpose at creation Attach a named owner and written purpose before the agent enters production.
- Replace inherited role scope with task-scoped permissions Grant permissions only for the specific lookup, workflow or action the agent must perform.
Bottom line: AI agent governance fails when teams assume static behaviour in a runtime system, because the real risk is scope drift and not authentication alone.

Agent identity maturity is now an access governance problem, not a model-risk side issue. The article shows that runtime tool use, inherited scope and delayed revocation create the real exposure surface. That means AI agent identity has to be governed like a live entitlement class, not a static integration artifact. The practitioner conclusion is simple: if the token can outlive the task, the control model is already behind.
A few things that frame the scale:
- 69% of security leaders agree identity management must fundamentally shift to address agentic AI systems, according to the 2026 Infrastructure Identity Survey.
- 53% of security leaders expect AI to run major portions of their infrastructure autonomously within the next three years, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: What is the difference between vaulting a secret and reducing blast radius for an AI agent?
A: Vaulting improves storage hygiene, but it does not change what the credential can reach. Blast radius falls only when permissions are scoped to the task, ownership is explicit, and revocation is fast enough to stop reuse before the agent or attacker can exploit the token.
