AI agent identity control: are legacy IAM models enough?

TL;DR: AI agents are being folded into enterprise identity control planes through protocols like XAA, but the article argues that enterprise complexity, preview status, and coordination overhead still limit practical adoption, according to WorkOS. The deeper issue is that agent identity is being treated like a normal delegated session when runtime autonomy and cross-app access change the governance model.

By the numbers:

• Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.

Questions worth separating out

Q: How should security teams govern AI agents that access multiple applications?

A: Treat each agent as a non-human identity with a defined owner, lifecycle state, and revocation path.

Q: Why do AI agents complicate traditional IAM governance models?

A: Because IAM governance usually assumes access is granted to a known subject, then reviewed on a human or schedule-driven cadence.

Q: What breaks when agent access is bolted onto existing IAM stacks?

A: The biggest failure is assuming the existing control plane can absorb new delegation patterns without redesign.

Practitioner guidance

• Map agent delegation chains end to end Document every application, token exchange, and consent hop an AI agent can traverse.
• Inventory AI agents as managed non-human identities Assign each agent a named business owner, lifecycle state, and revocation path.
• Validate protocol participation before policy rollout Check which downstream applications actually support the delegation model before enforcing controls that depend on it.
