TL;DR: Spreadsheet-based access reviews fail in SaaS-heavy environments because static exports cannot keep pace with changing entitlements, fragmented SaaS authorization models, and disconnected remediation, according to OpenIAM. The governance gap is not reviewer effort but an access-certification model built for stable systems that no longer exist.
NHIMG editorial — based on content published by OpenIAM: Why Spreadsheet-Based Access Reviews Fail in SaaS Environments
Questions worth separating out
Q: How should security teams run access reviews in SaaS-heavy environments?
A: They should replace spreadsheet-only campaigns with live, source-system aligned reviews that preserve entitlement context and verify remediation.
Q: Why do spreadsheet-based access reviews fail as environments become more dynamic?
A: They fail because the access state changes continuously while the spreadsheet remains static.
Q: What do organisations get wrong about hybrid access certification?
A: They assume a unified export creates a unified control.
Practitioner guidance
- Move access certification to live data sources Connect review workflows directly to current entitlement data from SaaS platforms, directories, and admin consoles so reviewers assess the present state rather than exported snapshots.
- Preserve entitlement context in every review record Include source system, business owner, role purpose, and privilege indicator fields so reviewers can evaluate access meaningfully instead of guessing from technical labels.
- Separate certification from enforcement tracking Require a confirmed remediation status for each revoked entitlement and keep the review open until the target system change is verified.

Spreadsheet access reviews fail because they assume access is stable long enough to certify. That assumption was designed for slower on-prem environments with limited change velocity. It fails when SaaS entitlements mutate continuously and the review artifact is stale before the reviewer acts. The implication is that governance models built on periodic snapshots no longer describe the real access state.
A few things that frame the scale:
- 88.5% of organisations acknowledge that their non-human IAM practices lag behind or are merely on par with their human identity and access management efforts, according to the 2024 Non-Human Identity Security Report.
- Only 19.6% of security professionals express strong confidence in their organisation's ability to securely manage non-human workload identities.
A question worth separating out:
Q: Who is accountable when access removals are approved but not enforced?
A: The identity governance owner remains accountable until the removal is verified in the target system. A documented approval is not the same as a completed control. Regulated programmes should treat unverified revocations as open remediation items, because the control is not complete until enforcement is confirmed.
