TL;DR: Unosecur reports that non-human identities now outnumber human identities by 25x to 50x in modern enterprises, yet many teams still govern them as if machine access behaves like human access. That assumption breaks across lifecycle control, privilege scope, and monitoring, making NHI governance a primary identity security problem.
Editorial analysis by NHI Mgmt Group, based on content published by Unosecur: “Securing Non‑Human Identities: Mitigation Strategies”.
Key questions
Q: What breaks when non-human identities are governed like human users?
A: Lifecycle triggers, ownership, and review processes stop working because machine identities do not generate joiner, mover, or leaver events.
Q: Why do over-privileged service accounts increase production breach impact?
A: Because production service accounts often sit inside the trust fabric of the live environment, excessive permissions let one compromised identity reach many systems.
Q: How do security teams know whether NHI rotation is actually working?
A: Rotation is working only if teams can show that every exposed credential was found, replaced, and validated against downstream dependencies without disrupting production.
Practitioner guidance
- Define NHI ownership for every credential Assign a business or technical owner to every service account, API key, token, and certificate so no machine identity exists without a revocation path and a clear renewal decision.
- Reduce standing privilege in machine access paths Review NHI permissions for broad roles, shared secrets, and cross-environment access that exceed task scope, then shrink access to the smallest workable set of resources.
- Automate rotation for secrets and certificates Set enforced expiry windows for keys, tokens, and certificates, and make sure dependent workloads can reauthenticate without manual intervention when credentials change.
Bottom line: The central NHI problem is not only credential sprawl but governance that still assumes machine access behaves like human access.

NHI governance is failing where teams still assume machine access can be managed like human access. Human-centric access models depend on login sessions, user behavior, and review cadences that do not map cleanly to service accounts, tokens, and automation credentials. The result is predictable: ownership gets vague, privilege accumulates, and offboarding becomes an afterthought. Practitioners need to treat machine identity as a distinct governance domain, not an IAM subcase.
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.
A question worth separating out:
Q: Should organisations prioritise zero trust or NHI governance first?
A: Organisations should treat them as dependent priorities rather than competing projects. Zero trust fails quickly when NHIs are over-permissioned, undocumented, or impossible to revoke. NHI governance gives zero trust the inventory, ownership, and lifecycle controls it needs to work in cloud operations.
