TL;DR: Access review campaigns often record revocation decisions without fully removing access, because remediation depends on tickets, integrations, and downstream execution, according to OpenIAM’s analysis. The real control failure is not review completion but unverified enforcement, which lets governance evidence outpace the actual access state.
NHIMG editorial — based on content published by OpenIAM: Why Access Review Remediation Often Fails After Certification
Questions worth separating out
Q: What fails when access review remediation does not fully execute?
A: The control fails at the enforcement stage, not the review stage.
Q: Why do access reviews sometimes leave risky access in place after certification?
A: Because certification and enforcement are often separated by ticket queues, ownership handoffs, and incomplete integrations.
Q: How can security teams tell whether access review remediation is actually working?
A: They should measure confirmed removal, not just review completion.
Practitioner guidance
- Verify post-remediation state, not just campaign closure. Require an automated or manually attested check that the revoked entitlement is absent from the target application, directory, or privileged path before the case is closed.
- Assign a named owner for every remediation path. Map each revocation to a clear operational owner, including application teams where entitlements are local to the system rather than centrally enforced.
- Reconcile equivalent entitlements after each revoke. Check direct assignments, inherited roles, group membership, and temporary privileges so a removed grant does not leave the same access intact through another route.

Access review remediation gap: why revoked access still lingers?
Explore further
Access review remediation gap is the real control failure, not certification completion. Certification proves that someone reviewed access and recorded a decision. It does not prove that the entitlement disappeared from the environment. That distinction matters because many IAM programmes still measure governance activity as if it were enforcement. The implication is that access review controls must be judged on state change, not attestation volume.
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.
- Two-thirds of enterprises have endured a successful cyberattack resulting from compromised non-human identities, with a quarter encountering multiple attacks, according to Oasis Security and ESG.
A question worth separating out:
Q: Who is accountable when revoked access remains active after an access review?
A: Accountability should sit with the governance owner for the review outcome and the operational owner for the system that enforces the change. If access survives because the process relies on unclear handoffs, then no one truly owns the final state. Frameworks such as the NIST Cybersecurity Framework 2.0 reinforce that control outcomes must be operationally effective, not merely documented.
