TL;DR: ISO 27001 user access reviews are meant to verify that users still have appropriate permissions, but the article shows how stale access, missing approvals, and weak evidence routinely break audit readiness according to SecurEnds. The real issue is not the review cadence itself, but whether organisations can prove access was removed, documented, and traceable when roles and people changed.
Editorial analysis by NHI Mgmt Group, based on content published by SecurEnds: “ISO 27001 User Access Review Master Guide”.
Key questions
Q: What breaks when ISO 27001 user access reviews do not produce audit evidence?
A: The review stops being defensible.
Q: Why do stale permissions create ISO 27001 governance risk even when reviews run on schedule?
A: Because the schedule does not correct the underlying access data.
Q: How do organisations know whether access reviews are working?
A: Access reviews are working when they lead to timely removals, reduced exception volume, and role definitions that stop accumulating unused rights.
Practitioner guidance
- Strengthen review evidence integrity Record reviewer identity, decision, timestamp, and entitlement change for every access certification cycle so auditors can reconstruct the full path from review to revocation.
- Separate privileged access reviews Route admin and elevated permissions through a dedicated workflow with explicit approvals and separate sign-off from standard user access.
- Reconcile lifecycle sources before review Compare HR, directory, SaaS, and cloud records before certification begins so movers and leavers do not inflate the entitlement list.
Bottom line: The article shows that ISO 27001 access reviews fail most visibly when organisations cannot prove the review happened in an audit-grade way.

ISO 27001 user access review is an evidence problem before it is a scheduling problem. Organisations often focus on whether reviews happen quarterly or twice yearly, but auditors care more about whether the outcome is provable. If the organisation cannot show approvals, removals, and reviewer ownership, the control exists only in policy form. The practitioner conclusion is simple: access governance must be built around evidence quality, not calendar frequency.
A question worth separating out:
Q: Should privileged access reviews be handled separately from standard user access reviews?
A: They should be governed differently because privileged accounts carry higher blast radius and tighter accountability requirements. Standard access review can focus on broad entitlement validity, while privileged review must also verify business justification, dormant account status, and deprovisioning evidence. Combining them without extra scrutiny hides the riskiest access.
