TL;DR: Zero trust security depends on continuous verification, least privilege, and explicit access decisions, but many programmes still apply it as a perimeter concept rather than an identity discipline, according to Netwrix. That gap matters because NHI, human, and autonomous access all break differently when trust is assumed instead of re-evaluated.

Questions worth separating out
Q: How should security teams implement zero trust across human and non-human identities?
A: Start by aligning access policy, entitlement review, and session verification across both human users and non-human identities.
Q: Why do service accounts complicate zero trust programmes?
A: Service accounts complicate zero trust because their access often persists long after the original task or deployment need has changed.
Q: What do security teams get wrong about zero trust and network access?
A: Teams often assume that if network access is mediated, the identity problem is solved.
Practitioner guidance
- Recast zero trust as an identity governance programme Anchor the operating model in authentication, entitlement review, secrets rotation, and privileged session control rather than network segmentation alone.
- Inventory standing privilege across human and non-human identities Identify service accounts, tokens, certificates, and delegated admin roles that persist outside task windows, then classify them by blast radius and offboarding risk.
- Apply just-in-time access to high-risk access paths Use task-scoped elevation for privileged human access and replace persistent machine entitlements with narrow, time-bound approvals where workflow supports it.

Zero trust only works as an identity model when access is continuously re-evaluated at the point of use. The architecture is often described as a network stance, but the real control boundary is identity, privilege, and context. If the request is not rechecked at the moment it matters, then the programme is still relying on trust by default. Practitioners should treat zero trust as an enforcement model for identities, not a label for segmentation.
A few things that frame the scale:
- 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, according to The State of Non-Human Identity Security.
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, compared to nearly 1 in 4 for securing human identities.
A question worth separating out:
Q: How do you know if zero trust is actually working?
A: Look for evidence that access is continually re-evaluated and that standing privilege is shrinking across users, service accounts, and privileged roles. If entitlements remain broad, long-lived, or hard to map to ownership, the programme is behaving like perimeter control with modern branding rather than true zero trust.
