TL;DR: Unosecur says the OWASP NHI Top 10 shows machine identities now outnumber human users, yet service accounts, API keys, OAuth apps, and workload identities are still governed far less rigorously than human accounts. The gap is that identity control planes were built for people, while machine access now defines the real attack surface.
Editorial analysis by NHI Mgmt Group, based on content published by Unosecur: “Securing the Machine Perimeter: OWASP NHI Top 10 Breakdown”.
Key questions
Q: What breaks when non-human identities are not offboarded properly?
A: Orphaned NHIs remain valid long after the workload or integration they served is gone, which gives attackers a durable access path.
Q: Why do static NHI credentials increase third-party breach impact?
A: Static NHI credentials increase third-party breach impact because they persist beyond the moment of use.
Q: What are the signs that machine identity management is failing in an organisation?
A: Common signs include incomplete inventory, spreadsheet based tracking, manual renewal processes, unclear ownership, and repeated certificate expiry events.
Practitioner guidance
- Inventory every machine identity source Build a single view across cloud IAM, CI/CD, SaaS apps, secrets stores, and third-party integrations so service accounts, API keys, and OAuth apps are owned and classified.
- Enforce ownership and offboarding for NHIs Tie each non-human identity to a named system owner, defined expiry or review date, and a revocation path so abandoned credentials do not remain active.
- Replace long-lived secrets with shorter trust windows Reduce replayable credential exposure by limiting token lifetime, rotating secrets where rotation is still required, and removing credentials that persist after the workload changes.
Bottom line: Machine identities are now the main governance gap in modern cloud and SaaS environments, not a peripheral exception to human IAM.

Machine identity governance is now the missing layer between cloud IAM and real access control. Human IAM programmes can mature for years and still leave the machine estate effectively unmanaged. The article’s core point is that service accounts, API keys, OAuth apps, and workload identities are not edge cases but the default path through which modern systems operate. Practitioners should treat machine identity governance as a distinct operating discipline, not an extension of user access administration.
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: What problem does ownership attribution solve for service accounts and API keys?
A: It closes the gap between exposure detection and accountable remediation. Many organisations can find the secret, but not the human who introduced it, maintains it, or can safely replace it. Ownership attribution gives security teams a practical way to assign action without relying on informal knowledge that disappears during staff changes.
