TL;DR: Most AI agent governance programs stop at documentary or application-layer controls, while true enforceability requires independent runtime observation outside the agent’s process boundary, according to ARMO. The practical issue is not policy intent but whether security teams can prove enforcement held when middleware was bypassed or compromised.

Questions worth separating out
Q: What fails when AI agent governance stays inside the agent process?
A: It fails at verification.
Q: Why do AI agents create new risk in non-human identity management?
A: AI agents create risk because they operate as software identities with delegated authority, but many organisations do not track them with the same discipline applied to users or service accounts.
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
- Score AI agent clauses by enforceability level Classify policy statements as aspirational, documentary, attested, application-plane enforced, or two-plane verified, then prioritise the clauses that still lack external runtime evidence.
- Separate policy decisions from host-level evidence Collect telemetry from outside the agent process, including syscalls, network destinations, file access, and child processes, so enforcement can be checked independently of the workload’s own reporting.
- Validate agent identity scope end to end Review the service accounts, delegated tools, and credential boundaries used by each agent, then confirm those scopes are visible to the enforcement and observation layers.

AI agent governance and the runtime evidence gap?

AI agent governance now has a verification problem, not just a policy problem. Most programmes can describe what agents should do, but they cannot prove what happened when the agent executed outside the monitored path. That gap matters because security control only exists when it is independently observable. For AI governance teams, the practical conclusion is that documentation without external evidence should not be treated as enforceable control.
A question worth separating out:
Q: How should organisations decide whether to build or buy AI governance controls?
A: Choose build when the organisation needs deep custom instrumentation, strict data residency, and has dedicated engineering capacity to own the system long term. Choose buy when audit deadlines are close, governance coverage is needed quickly, or enforcement must be delivered faster than an internal team can build it. Hybrid approaches often work best for large enterprises.
