AI agent identity risk: what it means for IAM teams

TL;DR: AI agents are increasingly acting as machine identities that pull data, chain API calls, and communicate across systems without human approval, while traditional RBAC and quarterly reviews fail to keep pace, according to SecurEnds. Static identity models assume predictable roles and reviewable access, but autonomous runtime behaviour makes that assumption unreliable.

NHIMG editorial — based on content published by SecurEnds: AI agents and machine identities need their own identity governance model

By the numbers:

• 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, 46% confirmed and 26% suspected.
• When AWS credentials are exposed publicly, attackers attempt access within an average of 17 minutes, and as quickly as 9 minutes in some cases.

Questions worth separating out

Q: How should security teams govern AI agents that act like machine identities?

A: They should treat AI agents as identities with owners, scoped permissions, runtime boundaries, and revocation rules.

Q: Why do traditional access reviews fail for AI agents and machine identities?

A: Traditional reviews fail because they assume access persists long enough to be observed and certified later.

Q: What breaks when AI agents get long-lived credentials?

A: Long-lived credentials create shadow access because the agent can continue to act after the business need has ended.

Practitioner guidance

• Inventory AI agents as first-class identities Build a live register of agent identities, their owners, data sources, tool permissions, and execution boundaries.
• Replace role-only access with task-scoped controls Bind permissions to the task, environment, and runtime context the agent is currently executing, then remove them when the task ends.
• Automate credential expiry and revocation Issue short-lived tokens, keys, and certificates for agent workflows, and revoke them automatically when the workflow completes or changes state.
