TL;DR: Non-human identities are now common enough that the security challenge is no longer about recognising them, but about changing the operating model that governs them, according to Orchid Security. The practical shift is from human-centric IAM habits to lifecycle, privilege, and monitoring controls that assume machine identities behave differently.
Editorial analysis by NHI Mgmt Group, based on content published by Orchid Security: “Why non-human identities (NHIs) require a change in mindset”.
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 NHIs increase access risk even when authentication is working?
A: Authentication can be fine while governance is still wrong.
Q: How can security teams tell whether NHI governance is working?
A: They should look for fewer orphaned accounts, shorter credential lifetimes, lower secret reuse and faster decommissioning when systems or projects end.
Practitioner guidance
- Inventory NHIs by function and owner Build an inventory that records the business function, technical owner, issuing system and expected lifetime for every service account, token, key and certificate.
- Separate NHI lifecycle from human JML Create offboarding and review paths for machine identities that do not depend on employee status changes, team transfers or HR-driven access events.
- Tighten privilege around task scope Reduce each machine identity to the narrowest runtime scope it needs, then review whether its actual usage still matches the original job it was created to perform.
Bottom line: The article's central warning is that non-human identities cannot be governed effectively with human IAM assumptions alone.

NHIs are now a governance category, not a niche exception: When machine identities outnumber human identities at enterprise scale, the control problem stops being whether teams can catalogue them and becomes whether the programme is built to govern them at all. Human-centric IAM was designed around enrolment, interactive authentication and periodic review. That model does not describe service accounts, API keys or workload credentials with the same precision, so governance quality depends on whether ownership, lifecycle and privilege are explicit. The practitioner conclusion is straightforward: NHI is a first-class identity population, not an edge case.
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 NHI lifecycle controls before expanding monitoring?
A: Yes, because monitoring without lifecycle control only shows that unmanaged access exists. Teams should first establish ownership, purpose and retirement rules, then use telemetry to confirm that access still matches those boundaries.
