TL;DR: AI agent approval needs Least Agency because agents can chain actions, use multiple tools, and spread the impact of broad permissions across business systems, according to ThreatLocker. Agent authority has to stay narrow enough to enforce, attribute, and revoke before harm spreads.
Editorial analysis by NHI Mgmt Group, based on content published by ThreatLocker: “Seven questions to ask before approving an AI agent”.
Key questions
Q: Why do AI agents need their own identity instead of borrowed human credentials?
A: AI agents need their own identity because borrowed human credentials destroy auditability, make revocation imprecise, and expand blast radius.
Q: What breaks when AI agents have broader access than their tasks require?
A: Over-privileged agents break segregation of duties, weaken auditability, and expand blast radius across transactions, data lookups, and workflow triggers.
A: Security teams should separate authentication from action approval.
Practitioner guidance
- Define least agency for every agent Document the exact business outcome, the excluded actions, the intended users, and the systems the agent may touch before deployment.
- Issue distinct agent identities Avoid shared administrator accounts and copied employee credentials.
- Bind approval to high-risk actions Require human approval only for sensitive, externally visible, privileged, financially binding, or hard-to-reverse actions, and bind that approval to the exact tool call and target.
Bottom line: AI agents introduce governance risk because they can chain actions, use multiple tools, and carry the impact of overly broad permissions into business systems.

AI agent approval is now an identity governance problem, not a software review problem. The article is not really about questionnaires. It is about whether the organisation can define, constrain, attribute, and revoke a non-human actor that can execute tasks with its own delegated authority. That is an IAM, PAM, and NHI governance decision disguised as an operational checklist. Practitioners should treat approval as the start of policy enforcement, not the end of due diligence.
A question worth separating out:
Q: What should teams do immediately when an AI agent behaves unpredictably?
A: Suspend the agent's high-risk access, preserve the prompt and tool-call trail, and review the inputs that may have redirected its behaviour. Containment should happen before the session continues, because the same trust failure can propagate through every subsequent action.
