TL;DR: Hidden machine accounts remain a governance challenge, and identity visibility may be part of the answer, according to Hydden’s analysis. For identity teams, visibility without lifecycle ownership still leaves NHI risk unmanaged.
Editorial analysis by NHI Mgmt Group, based on content published by Hydden: “Dark Reading: Startup Finds Hydden Identities IT Environment”.
Key questions
Q: What breaks when hidden machine identities are discovered but not owned?
A: Discovery without ownership breaks the governance chain because no one can certify, rotate, or retire the identity with authority.
Q: Why do hidden NHIs keep creating risk even after discovery programmes improve?
A: They keep creating risk because discovery changes what the team can see, not what the team can govern.
Q: What are the signs that human identity and NHI governance is failing?
A: Common signs include orphaned NHIs, unclear ownership, outdated permissions, weak visibility into who can access what, and inconsistent key rotation or access review processes.
Practitioner guidance
- Define ownership for every discovered NHI Require a named business owner, technical owner, and service dependency for each machine identity before it is accepted into the managed estate.
- Tie discovery to recertification workflows Route newly discovered accounts into access review and certification processes so teams can confirm whether the identity is still required.
- Separate active from dormant identities Tag NHIs by last use, business service, and retirement date so stale identities can be prioritised for revocation.
Bottom line: Identity visibility can uncover hidden machine accounts, but visibility alone does not solve the governance problem.

Identity visibility is only the first half of NHI governance: discovery tells you what exists, but it does not prove who owns it or whether it should still be active. That means visibility can reduce uncertainty while leaving entitlement risk untouched. For machine identities, the control failure is not lack of inventory alone, but absence of governed lifecycle decisions after inventory is built. Practitioners should treat discovery as the intake point for governance, not the endpoint.
A few things that frame the scale:
- Nearly 60% of IT leaders cite restrictive cost and complexity as a weakness of legacy identity governance, according to the 2025 State of Identity Governance Report.
A question worth separating out:
Q: How should teams govern machine identity in mixed human and device environments?
A: Teams should govern machine identity as a separate identity class with its own inventory, authentication method, and review cycle. Devices, cameras, robots, and similar assets should not inherit assumptions designed for people. If they do, the programme misses a major part of the attack surface and leaves trust unmanaged.
