TL;DR: Machine identities need explicit ownership, lifecycle, and revocation rules, according to Saviynt. Access reviews, offboarding, and privilege scoping still have to work when credentials belong to service accounts or AI-driven workflows.
Editorial analysis by NHI Mgmt Group, based on content published by Saviynt: “Newsroom”.
Key questions
Q: Why do machine identities create gaps in access review programmes?
A: Because many machine credentials remain active through business and application change while review cycles are still periodic.
A: Security teams should not rely only on stale records or manual lists.
Q: How should security teams govern non-human identities in cloud environments?
A: Start with complete discovery, because you cannot govern what you cannot see.
Practitioner guidance
- Define ownership for every non-human identity Assign a business owner, technical owner, and service purpose to each service account, API key, token, or certificate so accountability exists before access is granted.
- Tie recertification to lifecycle events Use joiner-mover-leaver logic for machine identities by triggering review when an application, integration, or process changes instead of waiting for periodic recertification alone.
- Separate human and machine entitlement reporting Report human access and non-human access separately so orphaned credentials, over-scoped service accounts, and application-linked secrets are not hidden inside one aggregated view.
Bottom line: The core problem is not platform coverage but whether machine identities are governed with explicit ownership, lifecycle, and revocation rules.

Identity cloud breadth only matters if it closes the NHI lifecycle gap. A platform that spans human and non-human access can reduce tool sprawl, but breadth is not governance. The real test is whether the programme can prove ownership, revocation, and recertification for machine identities with the same discipline used for human access. Without that, the organisation has centralised control points but not control.
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: What is the difference between access convenience and access governance for NHIs?
A: Access convenience focuses on making connections easy, while access governance focuses on constraining what a non-human identity can do, for how long, and under which conditions. Convenience may reduce friction, but governance reduces blast radius. For NHIs, the distinction matters because automation can scale misuse faster than human admins usually can.
