TL;DR: AI agents that can act with stolen API keys and delegated access create an identity problem, not just a model-security problem, according to Beyond Identity. The critical assumption is that access can be safely bound to a credential alone, when autonomous or semi-autonomous agents can reuse that access at runtime without human intent or hardware assurance.
Editorial analysis by NHI Mgmt Group, based on content published by Beyond Identity: “The Importance of Authentication”.
Key questions
Q: Why are AI agents harder to trust with credentials than traditional workloads?
A: AI agents are non-deterministic, so their tool use and outputs can change based on prompts, context, and external content.
Q: Why do AI agents create a different authorisation problem from ordinary automation?
A: Ordinary automation follows predefined rules, so the access path is known before execution starts.
Q: How should security teams decide where hardware-bound identity is necessary?
A: Use it where agent compromise would create a material impact, such as access to production systems, customer data, secrets, or administrative functions.
Practitioner guidance
- Map AI agent access to runtime trust boundaries Identify every agent workflow that can reach sensitive systems, then document whether the access depends only on a bearer credential or also on a verifiable hardware-backed execution context.
- Separate low-risk and high-risk agent pathways Apply stronger binding and attestation requirements to agents that can access secrets, production data, or administrative APIs, and keep lower-risk paths on simpler controls where justified.
- Rework agent offboarding and revocation Treat delegated agent access as a lifecycle state that must be explicitly revoked when the workload, model, or environment changes, not as a standing entitlement that can be left in place.
Bottom line: AI agents change identity assurance by making runtime use of delegated access more important than the original credential grant.

Credential possession is not identity assurance for AI agents: The old premise was that the bearer of a token or API key was close enough to the intended actor for access decisions to remain valid. That premise fails when an AI agent can reuse delegated access at runtime without a human being present to reassert intent. The implication is that possession-based controls no longer describe the full trust model for agentic systems.
A few things that frame the scale:
- Gartner predicts that more than 40% of agentic AI projects will be cancelled by the end of 2027, citing rising costs, unclear value and insufficient risk controls.
A question worth separating out:
Q: Who should own AI agent identity governance in an enterprise?
A: AI agent identity governance should sit jointly with IAM, platform security, and application owners because the risk crosses the runtime, the proxy, and the receiving service. No single team can see the whole delegation chain unless identity context is preserved end to end.
