TL;DR: Non-human identities now outnumber humans 45 to 1 in many enterprises, and Token Security argues that AI agents are accelerating both identity creation and overprivileged access, turning machine credentials into a primary attack surface. Static IAM, periodic audits, and human-centric governance no longer match machine-speed identity sprawl.
Editorial analysis by NHI Mgmt Group, based on content published by Token Security: “Why Non-Human Identities Security Risks Are Rising in AI Enterprises”.
Key questions
Q: What breaks when non-human identities have more access than they need?
A: When non-human identities carry excess access, a single compromise can move from a local incident to broad cloud control.
Q: Why do AI agents increase non-human identity risk?
A: AI agents increase non-human identity risk because they can execute many actions quickly once they inherit a credential or tool permission.
Q: What are the signs that machine identity management is failing in an organisation?
A: Common signs include incomplete inventory, spreadsheet based tracking, manual renewal processes, unclear ownership, and repeated certificate expiry events.
Practitioner guidance
- Map every machine identity to an owner Build an authoritative inventory across cloud, CI/CD, SaaS, and AI workflows, then attach a named owner and business purpose to each credentialed entity.
- Right-size broad roles on service accounts Review machine identities that carry admin or editor permissions but only perform narrow tasks, then remove unused access paths and document the minimum required scope.
- Rotate secrets automatically and shorten credential lifetime Replace static tokens and keys with ephemeral issuance where possible, and set rotation so unused credentials cannot survive long enough to become forgotten attack paths.
Bottom line: Non-human identity risk in AI enterprises is rising because machine credentials are being created faster than ownership and lifecycle controls can keep up.

Non-human identity sprawl is now a governance problem, not a tooling problem. The article shows that machine identities are not just more numerous than human accounts, they are created, consumed, and forgotten across cloud, CI/CD, and AI workflows. That means ownership, review, and lifecycle controls are failing at the programme level, not just at the implementation layer. Practitioners need to treat NHI inventory quality as a prerequisite for identity governance.
A few things that frame the scale:
- NHIs outnumber human identities by 25x to 50x in modern enterprises, according to the Ultimate Guide to NHIs.
- 1 in every 1,000 non-human identities in enterprise environments is more than 10 years old.
A question worth separating out:
Q: How can organisations reduce the blast radius of compromised build credentials?
A: Use short-lived credentials, separate build and deploy privileges, and require audited approval paths for production changes. If a build identity is compromised, it should not be able to move laterally into secrets stores or cloud administration. The goal is to make one exposed token useful for only one narrow task.
