TL;DR: Unosecur explains that Zero Trust only works for non-human identities when teams treat service accounts, API keys, bots, and workloads as first-class identities with owner assignment, least-privilege scopes, short-lived tokens, and continuous verification. The core governance gap is that standing access and unmanaged machine identities still defeat the model’s assumptions.
Editorial analysis by NHI Mgmt Group, based on content published by Unosecur: “Zero Trust”.
Key questions
Q: What breaks when non-human identities have standing access in a Zero Trust model?
A: Standing access breaks the core Zero Trust assumption that each request is explicitly evaluated.
Q: Why do overprivileged service accounts create such persistent cloud risk?
A: Overprivileged service accounts create persistent risk because they combine standing access, weak ownership, and broad lateral movement potential.
Q: What are the signs that NHI governance is failing in a Zero Trust programme?
A: Common signs include orphaned service accounts, wildcard cloud permissions, credentials with no named owner, and tokens that outlive the workflows they support.
Practitioner guidance
- Assign named owners to every NHI Create a complete inventory of service accounts, API keys, bots, and workload identities, then require a human owner and business purpose for each one.
- Replace standing privilege with task-scoped access Use Just-In-Time issuance and automatic expiry for privileged machine access so credentials exist only for the duration of a specific task.
- Right-size cloud entitlements continuously Review cloud permissions for wildcard rights, unused grants, and privilege creep, then reduce scopes to the minimum needed for current workflows.
Bottom line: Non-human identities are not a side case in Zero Trust, because they often carry the longest-lived and broadest permissions in the environment.

Zero Trust only becomes real when non-human identities are governed as identities, not as plumbing. Service accounts, API keys, and workloads are often treated as implementation detail, yet they are the access layer that Zero Trust is supposed to control. When those identities are unowned or over-scoped, the model loses its ability to enforce least privilege at the point of use. The practitioner conclusion is simple: Zero Trust fails where NHI governance is still informal.
A few things that frame the scale:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to the Ultimate Guide to NHIs.
- 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: How should teams combine Zero Trust and NHI lifecycle management?
A: Teams should connect lifecycle events to access decisions so creation, rotation, expiry, and offboarding are enforced as part of the same control plane. That means treating machine identities like governed identities with owners, scope, and retirement rules, not as static configuration objects hidden inside infrastructure.
