TL;DR: Machine identities outnumber humans by more than 80 to 1, and the source argues that treating all non-human identities as one category obscures the access, rotation, and revocation controls needed for Zero Trust and AI agent governance, according to CyberArk. Precision, not broad labeling, is now the practical security boundary for machine identities.
Editorial analysis by NHI Mgmt Group, based on content published by CyberArk: “Precision in Machine Identity: Securing the NHIs That Matter”.
Key questions
Q: What breaks when all machine identities are treated as one NHI category?
A: The control model loses the distinctions that make access governance workable.
Q: Why do machine identities increase lateral movement risk in cloud and SaaS environments?
A: Machine identities often have persistent access, broad integration reach and fewer human friction points than user accounts.
Q: How do security teams know whether machine identity governance is working?
A: They know it is working when every non-human credential has a named owner, a visible system scope, and a documented retirement path.
Practitioner guidance
- Define machine identity classes explicitly Separate service accounts, API keys, tokens, certificates and agent identities into distinct inventory groups with different owners, policies and revocation paths.
- Map access to identity type Apply different access rules to workloads, APIs, containers and AI agents so entitlement decisions reflect the thing authenticating, not a generic non-human label.
- Build revocation into machine identity lifecycle Ensure every machine identity can be traced, rotated and revoked quickly when misuse, compromise or scope drift is detected.
Bottom line: Machine identity precision matters because the same controls do not fit every non-human actor, and broad NHI language hides that mismatch.

Machine identity precision is now the control plane, not a terminology debate. Broad NHI language masks the real governance problem, which is that certificates, keys, tokens and service accounts do not fail in the same way. When teams cannot distinguish the identity type, they cannot define the correct lifecycle, policy boundary or owner. The implication is that identity programmes must stop optimising for inclusive labels and start optimising for enforceable control boundaries.
A question worth separating out:
Q: What is the difference between NHI and machine identity?
A: Machine identity refers specifically to identities assigned to physical or virtual machines and devices. Non-Human Identity is the broader category that encompasses machine identities but extends to software workloads, service accounts, API keys, OAuth tokens, bots, RPA agents, CI/CD pipeline identities, and AI agents.
