TL;DR: AI agents widen least privilege risk because their workflows can span multiple applications, scripts and data sources inside one task, according to ThreatLocker. Access governance has to track the agent’s downstream actions, or one compromise can spread across systems and workflows.
Editorial analysis by NHI Mgmt Group, based on content published by ThreatLocker: “The principle of least privilege for AI agents”.
Key questions
Q: Why do AI agents increase blast radius when permissions are too broad?
A: Because one compromised agent can act across multiple systems faster than a human and with fewer checkpoints.
Q: What do organisations get wrong about AI agent authorisation?
A: They often treat agent access as a tooling problem instead of an identity problem.
Q: How should security teams apply least privilege to AI agents and NHIs?
A: Start by mapping each agent or workload to one narrow task, then grant only the permissions required to complete that task.
Practitioner guidance
- Define task-scoped agent identities Assign each AI agent a dedicated identity with permissions limited to one workflow or service function, not a shared account spanning multiple use cases.
- Constrain downstream application reach Restrict which files, systems, scripts and network destinations an agent can reach after authentication, including any tools it invokes during execution.
- Remove standing privilege from AI-linked accounts Use just-in-time elevation for any elevated action so the agent does not retain broad rights between tasks or across integrations.
Bottom line: AI agents widen the least privilege problem because their workflows can span multiple applications, scripts and data sources inside one task.

Least privilege for AI agents is really a workflow authorisation problem. The article shows that static identity controls are not enough when an agent can move from one application to another inside the same task. Permission has to travel with the workflow, or the initial approval becomes meaningless as soon as the agent invokes a second system. The practitioner takeaway is that task scope, not just account scope, now defines the real control boundary.
A few things that frame the scale:
- 69% of security leaders agree identity management must fundamentally shift to address agentic AI systems, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: How do organisations know whether AI is truly under governance control?
A: They should be able to show where AI is recommend-only, where it can act, who owns each AI identity, what evidence is logged, and how access is revoked. If those answers live in different tools or are informal knowledge, the programme does not yet have defensible control over AI.
