TL;DR: Machine identities, including AI agents, now access enterprise systems continuously and often with broader permissions than security teams can easily see, according to BigID. The governance gap is no longer just credential management, because data context now determines whether non-human access is operational or materially exposing sensitive records.
NHIMG editorial — based on content published by BigID: Machine identity security now depends on data context and AI visibility
Questions worth separating out
Q: What should security teams prioritise first for machine identity governance?
A: Start with discovery, ownership, and privilege scope.
Q: Why do AI agents make non-human identity governance harder?
A: AI agents make governance harder because they can request tools, act autonomously, and change behaviour across sessions while still relying on machine credentials.
Q: What do security teams get wrong about machine identity management?
A: Security teams often treat certificates, keys, and tokens as infrastructure details instead of governed identities.
Practitioner guidance
- Map machine identities to sensitive data reach Build an inventory that links each service account, API, workload, and AI agent to the data stores it can actually access, including regulated and confidential data.
- Prioritise remediation by exposure, not account count Rank non-human identities by the sensitivity of reachable data, breadth of permissions, and whether AI systems can move data between applications.
- Separate ownership across platform teams and governance teams Assign a clear control owner for machine identity lifecycle, then reconcile cloud, DevOps, application, and AI platform inventories into one review cycle.
What's in the full article
BigID's full article covers the operational detail this post intentionally leaves for the source:
- How BigID links machine identities to specific sensitive data stores across cloud, SaaS, AI, and hybrid environments
- How the platform prioritises non-human access risk based on data sensitivity and exposure context
- How BigID monitors AI-driven activity to surface excessive access and risky data movement patterns
- How the vendor frames machine identity exposure as a data security problem rather than a pure secrets problem

Machine identity security is now a data governance problem, not a credential checklist. The article is right to move the discussion away from secrets alone. Credentials matter, but they are only the doorway; the real control question is what sensitive data the non-human identity can actually reach. That shifts prioritisation toward data-aware governance across IAM, IGA, PAM, and DSPM.
A few things that frame the scale:
- 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, with 38% having no or low visibility and 47% having only partial visibility, according to The State of Non-Human Identity Security.
- Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, compared to nearly 1 in 4 for securing human identities.
A question worth separating out:
Q: How do teams know whether machine identity controls are actually working?
A: Look for complete inventory coverage, clear ownership, regular credential rotation, and the ability to revoke access quickly without breaking dependent services. If identities still rely on spreadsheets, shared secrets, or manual exception handling, the control environment is not working at enterprise scale. The signal to watch is whether access can be governed without emergency intervention.
