TL;DR: Access reviews fail less because teams skip them than because discovery, context, and remediation are disconnected, according to Zluri, with 53% of security teams lacking continuous cloud and SaaS visibility according to Help Net Security. Access certification only reduces risk when review scope, reviewer context, and revocation are tied together end to end.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “Top Access Review Challenges IT Teams Face—Solved”.
By the numbers:
- 53% of security teams lack continuous and up-to-date visibility into their cloud and SaaS environments.
- Zluri can handle remediation across 800+ applications.
Key questions
Q: What breaks when access reviews only cover apps tied to SSO?
A: The review scope becomes incomplete because direct-login SaaS, department-owned tools, and shadow applications remain outside certification.
Q: Why do access review approvals turn into rubber-stamping without context?
A: Reviewers need usage, account status, and role-change information to judge whether access is still justified.
Q: Where does the access review process fail if revocation is manual?
A: It fails at enforcement.
Practitioner guidance
- Expand discovery beyond SSO Use browser, desktop, finance, and identity-linked signals to identify apps and accounts that never enter the review cycle through central provisioning.
- Embed reviewer context at decision time Show last login, usage trends, account status, and role-change indicators directly in the certification workflow so approvers can assess actual need.
- Close the revocation loop Route revoke decisions into direct enforcement paths that update the target app or entitlement source without waiting on a separate manual ticket.
Bottom line: Access reviews fail most often because organisations cannot see the full entitlement set, cannot judge access with enough context, or cannot enforce the decision cleanly.

Access review failure is a visibility failure before it is a workflow failure: the review population is often incomplete before any approver sees it. If unmanaged SaaS apps, contractor access, and shadow IT identities are missing from scope, the governance programme is certifying a partial estate and calling it control. That is a discovery problem, not a reviewer problem. The practitioner conclusion is that access certification quality starts with inventory quality.
A few things that frame the scale:
- Nearly 60% of IT leaders cite restrictive cost and complexity as a weakness of legacy identity governance, according to the 2025 State of Identity Governance Report.
A question worth separating out:
Q: When should organisations review access more frequently under ISO 27001?
A: Organisations should increase review frequency when the asset is sensitive, the privilege level is high, the user is external or short term, or the system could create regulatory, financial, or customer harm. The right cadence follows risk assessment, so a change in exposure should trigger a change in interval, not a fixed yearly habit.
