TL;DR: Overprivileged non-human identities are widening the attack surface because many are granted broad access, left poorly governed, and can be used to move laterally or escalate privileges if compromised, according to Entro Security's analysis and the 2025 State of NHI and Secrets report. Least privilege, ownership, and continuous review are now baseline controls, not optional hardening.
Editorial analysis by NHI Mgmt Group, based on content published by Entro Security: “NHI Threats & Mitigation Part 2: Overprivileged & Super NHIs”.
By the numbers:
- 90% of NHI tokens have excessive permissions, according to Entro Security.
- 44% of tokens are exposed in the wild, according to Entro Security.
Key questions
Q: What breaks when NHIs are given more access than their job needs?
A: The control that breaks is containment.
Q: Why do overprivileged agent identities create such a large security risk?
A: Because agents can turn ordinary tool access into destructive action at machine speed.
Q: How do teams know if NHI governance is actually working?
A: Look for complete inventory coverage, clear ownership, enforced rotation, and reliable decommissioning.
Practitioner guidance
- Map every NHI to a business owner Require a named human owner, a documented purpose, and an expiry trigger for each service account, token, and API key so accountability survives staff turnover and project change.
- Shrink permissions to task scope Review each machine identity against the exact databases, services, and cloud resources it must reach, then remove blanket read/write or administrative entitlements that are not needed.
- Review dormant and reused credentials Look for machine identities that have not changed with the workload, have no recent activity, or are shared across systems, because those identities are most likely to retain unnecessary access.
Bottom line: Overprivileged NHIs can turn one exposed token or service account into a broad access problem across cloud and application systems.

Identity blast radius is the right lens for overprivileged NHIs: the article shows that the primary risk is not a single bad credential but the range of systems that credential can reach once compromised. Excess access expands the attacker’s options across cloud, API, and microservice layers, so the security question becomes how far one identity can move before it is stopped. The practitioner conclusion is that blast-radius reduction must become a core identity objective, not a secondary hardening task.
A few things that frame the scale:
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job, according to the 2026 Infrastructure Identity Survey.
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: What should security teams do when a super NHI is discovered?
A: Contain the identity first by revoking unnecessary permissions, checking where the credential was used, and tracing what systems it could reach. The practical goal is to collapse the access path before the compromised identity can be reused for broader movement or persistence.
