TL;DR: Access governance, lifecycle control, and visibility fail when service accounts, API keys, and AI agents sit outside the programme, according to Zluri; the deeper issue is that identity governance still treats machine access as an exception instead of the operating model.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “Zluri Blogs”.
Key questions
Q: What problem does ownership attribution solve for service accounts and API keys?
A: It closes the gap between exposure detection and accountable remediation.
Q: Why do periodic access reviews create false confidence for machine identities?
A: Because they check status on a schedule while machine access changes continuously.
Practitioner guidance
- Inventory every non-human identity Build a complete register of service accounts, API keys, certificates, and AI agent credentials across cloud, SaaS, and internal systems.
- Assign lifecycle ownership Require a named owner for each NHI, with explicit creation, review, renewal, and retirement steps.
- Bring NHIs into access reviews Add machine identities to recertification and attestation workflows so reviewers can confirm scope, ownership, and necessity.
Bottom line: NHI governance fails when service accounts, API keys, and AI agents are treated as exceptions outside the main IGA model.

NHI governance has become an IGA design problem, not an adjacent operations task. The article’s core argument is that service accounts, API keys, and AI agents cannot be governed as exceptions if the programme claims to control who or what has access. That collapses the old boundary between identity administration and machine access oversight. Practitioners should treat non-human identity coverage as part of the operating model, not a backlog item.
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.
A question worth separating out:
Q: How do continuous offensive testing programs support zero trust and NHI governance?
A: They test whether assumptions about access, exposure and privilege still hold under realistic attack conditions. For NHI governance, that means checking whether exposed secrets, service accounts or tokens can actually be abused to reach data or control planes. For zero trust, it means proving that exposure does not automatically become trusted access just because it is authenticated.
