TL;DR: AI agents run as cloud identities through service accounts, IAM roles, and API keys, and Sonrai Security says 92% of cloud identities are already overprivileged, making autonomous access a bigger blast-radius problem than a new identity type. Least privilege and JIT controls now define whether agent behaviour stays contained or becomes breach material.
Editorial analysis by NHI Mgmt Group, based on content published by Sonrai Security: “Why AI Agents Need Least Privilege Too, and How to Enforce It Automatically”.
By the numbers:
- 92% of cloud identities are overprivileged, according to Sonrai Security.
Key questions
Q: What breaks when AI agents are given broad inherited permissions?
A: Broad inherited permissions break the assumption that access is tied to a narrow business need.
Q: Why does least privilege matter more for AI agents than for scheduled automation?
A: AI agents can make context-driven decisions during runtime, so permission scope directly determines what they are capable of doing in the moment.
Q: How can teams tell whether AI access is actually under control?
A: Look for evidence that access is limited by purpose, not just by account.
Practitioner guidance
- Define agent identities as first-class NHIs Inventory every AI agent credential, map it to a workload owner, and stop treating agent permissions as a side effect of application provisioning.
- Reduce standing privilege to the minimum reachable action set Strip unused permissions from roles used by agents, especially delete, write, and cross-account actions that expand blast radius.
- Move elevated access to task-bounded JIT Grant temporary permissions only for the duration of the agent task, then revoke them automatically when the task completes.
Bottom line: AI agents inherit cloud identity risk through service accounts, roles, and API keys, so governance should start with the same non-human identity controls used elsewhere in the environment.

AI agent identities are not a new identity class so much as a new pressure test for cloud IAM. Sonrai Security's article is useful because it avoids pretending the mechanism changed. The identity still authenticates through service accounts, IAM roles, and API keys, but the operational tempo is different, so review-driven governance is now lagging the actor it is meant to govern. The practitioner takeaway is that agent identity policy must be enforced at issuance, not interpreted after the fact.
A few things that frame the scale:
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems. Organisations failing to scope AI access properly are 4.5x more likely to experience a security incident, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: When does just-in-time access help most for AI agents?
A: JIT access helps most when agent tasks are episodic, high-risk, or difficult to predict in advance. It reduces standing exposure, but it works only if the agent's permissions are also tightly scoped and actively revoked after use. Otherwise, the temporary token masks a persistent privilege problem.
