TL;DR: IGA was built for human identities with stable ownership, HR-linked lifecycles, and periodic review, but modern environments are dominated by non-human identities that authenticate with secrets, change dynamically, and require runtime context for governance, according to Oasis Security. The old review model creates friction without clarity, and machine access now needs continuous validation rather than people-centric attestation.
Editorial analysis by NHI Mgmt Group, based on content published by Oasis Security: “Non-Human Identity Governance: Why IGA Falls Short”.
Key questions
Q: What breaks when non-human identities are not governed like human accounts?
A: Service accounts, API keys, tokens, and AI agents can retain access long after the original task ends because they do not naturally pass through joiner-mover-leaver processes.
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.
Q: How should security teams govern non-human identities that have persistent access?
A: Security teams should treat every non-human identity as a managed asset with an owner, an explicit purpose, a scoped privilege set, and a defined offboarding path.
Practitioner guidance
- Define machine identity ownership explicitly Assign a accountable owner for every service account, cloud service principal, automation bot, and AI agent so governance does not depend on ad hoc manual interpretation.
- Replace periodic review with continuous validation Use runtime usage and dependency data to reassess access as deployments, configurations, and automation change, instead of waiting for monthly or quarterly certification cycles.
- Map the full NHI relationship chain Track the application or workload, the secret used to authenticate, the bound identity, and the resource accessed so reviewers can see context rather than isolated entitlements.
Bottom line: Non-human identities do not fit the human lifecycle assumptions that IGA was built on, so governance based on HR-like review creates blind spots.

Human-centric governance breaks when the subject is not human. IGA was designed around stable ownership, HR-linked lifecycle events, and access decisions that can be reasoned about through business context. Non-human identities are created differently, change differently, and are often owned differently, so the governance premise itself fails before certification begins. The implication is that machine identities need a governance model built on operational behaviour, not a repurposed employee lifecycle.
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 organisations govern agentic AI and NHI access in the same programme?
A: Treat both as non-human identities that need ownership, scope, lifecycle, and usage controls. Agentic AI adds runtime decision-making, so you also need to evaluate whether access is still appropriate during execution, not only at provisioning. One programme should cover both, but the controls must reflect the actor’s behaviour.
