TL;DR: Access risk is no longer determined by permissions alone, because employees, service accounts, APIs, machine identities, and AI agents all inherit, accumulate, and misuse data access across hybrid environments, according to BigID. That shift makes data-aware governance essential: least privilege now depends on sensitive data context, activity, ownership, and business impact, not just entitlement reviews.
Editorial analysis by NHI Mgmt Group, based on content published by BigID: “What Is Data Access Management? How to Control Access and Reduce Risk”.
Key questions
Q: How should security teams govern AI agents that inherit authority from other identities?
A: Security teams should govern AI agents by tracking identity lineage, not just credentials.
Q: Why does data access risk depend on more than permissions?
A: Permissions show what an identity could do, not whether the access is active, who owns it, what data it exposes, or how damaging misuse would be.
Q: Why do service accounts and machine identities matter under NIS2?
A: Service accounts and machine identities matter because they often carry the permissions that move data, trigger reports, and feed AI workflows.
Practitioner guidance
- Discover sensitive data first Classify the data that matters most before ranking access, so permissions are judged against actual exposure rather than abstract entitlement lists.
- Map identity-to-data access paths Trace how employees, service accounts, APIs, machine identities, and AI systems reach sensitive repositories, including inherited access through roles, groups, and workflows.
- Add activity context to entitlement reviews Use usage telemetry to separate active, stale, unusual, and unused access, then prioritise the identities that touch regulated or confidential data.
Bottom line: Access governance is becoming a data-security problem because the same permission can be harmless or high risk depending on the data it reaches and who owns it.

Data access governance has become an identity problem because access now travels with the identity, not just the login event. Human users, contractors, applications, service accounts, APIs, machine identities, copilots, and AI agents all inherit permissions differently, but they can converge on the same sensitive dataset. The discipline now has to govern the identity chain behind the access path, not simply the access request. Practitioners should treat access as an identity lifecycle issue tied to data exposure, ownership, and business context.
A few things that frame the scale:
- 69% of organisations still authenticate machine identities with long-lived API keys, according to the 2026 State of AI Agent Identity Security Report.
A question worth separating out:
Q: How do teams decide which access to remediate first in a data governance programme?
A: Start with access that combines sensitive data, active use, weak ownership, and broad permissions. That combination creates the highest exposure because it indicates both reach and current exploitation potential. The right sequence is to reduce the permissions that touch high-value data and are still being used.
