GRC audit evidence gaps: what IAM teams need to fix

TL;DR: GRC audit and risk governance only works when control design, operating evidence, and accountability are connected across systems, because periodic compliance checks fail when audits cannot trace real execution, according to SecurEnds. The practical shift is from point-in-time review to continuous identity-aware evidence, not more documentation.

Questions worth separating out

Q: How should security teams prove that GRC controls are actually working?

A: They should tie every control to a specific evidence source such as access reviews, approval records, privileged activity, or change logs.

Q: Why do identity programmes matter so much in audit readiness?

A: Because identity records are the most reliable proof of who had access, who approved it, and whether access matched business need at the time.

Q: What breaks when audit evidence is spread across multiple systems?

A: Audit teams lose traceability, control testing slows down, and findings become harder to defend.

Practitioner guidance

  • Map audit controls to identity evidence sources Identify which access reviews, approval workflows, privileged sessions, and entitlement changes will serve as proof for each control.
  • Centralise evidence collection for identity events Pull review results, role changes, and privileged access logs into one audit-ready repository so teams are not rebuilding evidence from emails and exports during review periods.
  • Test control effectiveness continuously Move from periodic sampling to ongoing checks on whether access remains aligned with role, approvals are current, and exceptions are resolved before the next audit cycle begins.

Audit readiness is an identity evidence problem before it is a compliance problem. The article's central claim is correct: controls often exist, but governance fails when evidence is fragmented and cannot be reconciled across systems. That matters because auditors do not certify intent, they certify operating reality. For identity teams, this means the quality of access records, approval trails, and entitlement history now determines whether governance can be defended at all.

A few things that frame the scale:

  • 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, according to The 2024 ESG Report: Managing Non-Human Identities.
  • Enterprises that have experienced a compromised NHI averaged 2.7 separate incidents in the past 12 months, a pattern that shows governance gaps tend to repeat rather than remain isolated.

A question worth separating out:

Q: Who should be accountable for missing evidence in GRC audits?

A: Control owners should be accountable for the evidence their controls generate, while governance teams should own the process that detects and escalates gaps. If no one owns missing approvals, stale access reviews, or incomplete logs, the audit problem becomes a recurring operational failure.
