TL;DR: Periodic user access reviews remain a core control for limiting unauthorised access, detecting privilege creep, and supporting GDPR and PCI DSS compliance, according to Zluri’s guidance on reviews and audits. The real governance gap is not whether teams review access, but whether they can keep pace with role changes, contractors, vendors, and SaaS sprawl.

Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “User Access Reviews & Audits Best Practices To Monitor Privileges”.

Key questions

Q: How should security teams run user access reviews without missing stale permissions?

A: Start with a complete entitlement inventory that includes employees, contractors, vendors and inactive accounts, then certify access against current role and business need.

Q: Why do periodic access reviews leave organisations exposed?

A: Periodic reviews are snapshots, not continuous control.

Q: What do IAM teams get wrong about automation and RBAC?

A: Teams often assume automation will fix weak access design, but it only executes the role model already in place.

Practitioner guidance

  • Define a review scope that includes inactive users, contractors and vendors Build the certification list from the full access population, not only active employees, so dormant and third-party accounts are reviewed on the same cadence as staff entitlements.
  • Tie review outcomes to joiner-mover-leaver events Route approved removals and role corrections back into provisioning and deprovisioning workflows so access changes are not left as manual follow-up work.
  • Use RBAC as the review baseline Group access by role and job function before certification so reviewers can spot exceptions, excessive entitlements and mismatched assignments faster.

Bottom line: User access reviews remain necessary, but they only reduce risk when the access inventory is current and the remediation loop is closed.

Access review is only as strong as the lifecycle data behind it: Periodic certification does not control risk if the underlying account and entitlement state is already stale. The article shows that review outcomes depend on accurate user inventory, current role mapping and fast remediation, which makes lifecycle governance the real control surface. For IAM teams, the practical conclusion is that certification quality is an input problem, not just a reviewer workload problem.

A few things that frame the scale:

A question worth separating out:

Q: How can organisations know whether access reviews are producing real governance evidence?

A: Access reviews are working when they produce timestamped, role-specific evidence that a reviewer checked current access against policy and corrected what no longer fit. If the review only proves that a process happened, it is weak. If it proves what changed and why, it supports audit and risk decisions.
