TL;DR: Access reviews are the operational backbone of SaaS governance, but 1Password argues that spreadsheets, custom apps, and fragmented visibility still make them slow, inconsistent, and audit-prone. The real issue is that many organisations are reviewing access across tools their governance model cannot fully see or standardise.
Editorial analysis by NHI Mgmt Group, based on content published by 1Password: “Simplify access reviews with 1Password SaaS Manager”.
By the numbers:
- 1Password says its SaaS Manager includes over 350 native API integrations for popular applications.
Key questions
Q: What breaks when SaaS access reviews rely on spreadsheets?
A: Spreadsheets freeze access data in time, so reviewers work from stale exports while roles, teams, and app usage keep changing.
Q: Why do non-SCIM and custom apps make access reviews harder to govern?
A: They often cannot expose entitlement context in a standard way, so reviewers have to stitch together role, access level, and ownership information from multiple systems.
Q: How should teams connect access reviews to deprovisioning workflows?
A: Every review outcome should map to a clear enforcement path, such as removing access, adjusting permissions, or recording an approved exception.
Practitioner guidance
- Standardise the access review workflow Replace ad hoc spreadsheet cycles with one approved process for reviewer assignment, evidence capture, and decision logging across SaaS applications.
- Map review coverage by application type Identify which apps are SCIM-enabled, which depend on APIs, and which require CSV-based handling so review coverage gaps are visible before the next certification cycle.
- Link approval outcomes to remediation Make sure each approval, rejection, or exception can trigger deprovisioning, permission adjustment, or documented acceptance in the same control flow.
Bottom line: Spreadsheet-led access reviews create inconsistency because each SaaS application ends up being governed differently.

Spreadsheet governance is the symptom, not the control model. Once access reviews rely on manual files, the review process stops being a governed lifecycle and becomes a recurring reconciliation task. That distinction matters because spreadsheets cannot enforce completeness, consistency, or ownership across a SaaS estate with non-SCIM and custom applications. The practitioner conclusion is that access review quality is determined by workflow normalisation, not by review frequency alone.

A question worth separating out:
Q: What does good audit evidence look like for SaaS access reviews?
A: Good evidence shows who reviewed the access, when the review happened, what context they used, and what action followed. Reviewer names, timestamps, notes, and access-level detail matter because they prove accountability and support external audits. Without that structure, organisations may complete reviews operationally but still fail compliance testing.
