TL;DR: Manual access reviews break down as headcount, SaaS sprawl, and contractor use expand, leaving leavers, role changes, and privileged access decisions out of sync with reality according to Zluri. Automation changes access review from a periodic compliance task into a continuous governance control, but only if context, revocation, and audit logging are tied together.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “How Fast-Growing Tech Firms Automate Access Reviews”.
Key questions
Q: What breaks when access reviews are the main control for fast-growing companies?
A: Reviews become retrospective paperwork if permissions are changing faster than the review cycle.
Q: Why do poorly governed access reviews create compliance and security risk?
A: Poorly governed reviews create risk because reviewers often lack the context needed to judge whether access is still legitimate.
Q: How do teams know if automated access reviews are actually working?
A: Automated reviews are working when exception rates fall, reviewer overrides become rare, and access decisions are grounded in clean role definitions rather than ad hoc exceptions.
Practitioner guidance
- Centralise access inventory before running reviews Integrate HRIS, identity provider, and key SaaS applications so reviewers see current users, roles, and app entitlements from one workflow instead of reconciling spreadsheets.
- Trigger reviews on real identity events Launch access reviews when users change roles, contractors near end dates, or privileged access is granted, so governance follows business change instead of a calendar.
- Put revocation inside the review workflow Ensure denied access can be removed or downgraded directly from the review interface through native integration, API, or SCIM rather than via a separate ticket queue.
Bottom line: Manual access reviews become unreliable when growth, contractor churn, and SaaS sprawl outpace the review cadence.

Access review automation is becoming a control plane, not a reporting feature: the moment review decisions can trigger revocation, escalation, and evidence capture in one workflow, access review stops being a compliance task and becomes an operating control. That changes how IAM and IGA programmes are designed because the review is now part of enforcement, not a post hoc record. The practitioner conclusion is simple: if the control cannot change access, it is not governing access.
A few things that frame the scale:
- Over 70% of organisations lack automated access risk analysis, user access reviews and provisioning and deprovisioning, according to Pathlock's 2025 Digital Transformation and Access Risk Report.
A question worth separating out:
Q: Should access reviews be tied to joiner mover leaver events instead of quarterly cycles?
A: Yes, when the environment changes quickly. Event-driven reviews are better when role changes, contractor end dates, and privileged access grants create the real risk moment, because they align governance with actual identity change rather than a fixed calendar.
