User access reviews and audits: where IAM teams still miss risk

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.

By the numbers:

• Only 13% of organisations feel extremely prepared for the reality of agentic AI despite the majority racing toward autonomous adoption.

Questions worth separating out

Q: How should security teams run access reviews without creating audit theatre?

A: Start with a complete inventory of identities, applications, and permissions, then review only against documented business need.

Q: Why do user access reviews often fail to reduce privilege creep?

A: They fail when organisations treat them as periodic paperwork instead of lifecycle governance.

Q: How can organisations tell whether access reviews are actually working?

A: Look for evidence that reviews are complete, timely, and followed by real entitlement changes.

Practitioner guidance

• Map every review to a complete entitlement scope Include employees, contractors, vendors, inactive accounts, and all in-scope SaaS applications before starting the review cycle so certifiers are not working from partial data.
• Tie access reviews to joiner-mover-leaver events Trigger recertification when roles change, offboarding starts, or vendor relationships end so reviews remediate stale access instead of revalidating it.
• Separate role validation from access approval Use RBAC to simplify review, but require reviewers to confirm the role still matches business need rather than accepting inherited permissions by default.
