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.

NHIMG editorial — based on content published by Zluri: Lifecycle Management User Access Reviews & Audits Best Practices To Monitor Privileges

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.

What's in the full article

Zluri's full article covers the operational detail this post intentionally leaves for the source:

  • Monthly and quarterly access review workflows for user entitlements across business applications
  • RBAC-based review structure and how it simplifies approval decisions in practice
  • Operational steps for provisioning, deprovisioning, and lifecycle-triggered access changes
  • Examples of audit and compliance positioning for GDPR and PCI DSS

Access reviews are a control over stale authority, not a substitute for lifecycle management. The review process is designed for a world where granted access can be inspected before it becomes harmful, but many organisations now operate with frequent role churn, SaaS sprawl, and incomplete entitlement visibility. That means the real failure mode is not missing reviews, it is reviewing after the access has already outlived its business purpose. Practitioners should treat reviews as a verification layer above lifecycle hygiene, not as the lifecycle control itself.

A few things that frame the scale:

  • Two-thirds of enterprises have endured a successful cyberattack resulting from compromised non-human identities, with a quarter encountering multiple attacks, according to 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 question worth separating out:

Q: Who should be accountable for access review failures?

A: Accountability usually sits with the business owner who approves access, the IAM team that supplies the entitlement data, and the control owner who ensures remediation closes. Regulatory expectations such as GDPR and PCI DSS reinforce that access governance is shared, but the operational failure is usually a missing owner for cleanup after review.
