How should organisations reduce rubberstamping in user access reviews without slowing governance down?

Start by reducing the manual burden on reviewers. Automate review preparation, distribution, and revocation where possible, then focus managers only on decisions that need human judgment. Keep entitlements understandable, time bound, and tied to business need. If reviewers can act quickly with enough context, access certifications become more accurate and governance improves instead of turning into a checkbox exercise.

Why This Matters for Security Teams

Rubberstamping in access reviews usually appears when reviewers are asked to validate too many entitlements with too little context. The problem is not the review itself. It is the design of the review process: unclear ownership, stale role names, excessive frequency, and long entitlement lists that hide real risk. Current guidance from the NIST Cybersecurity Framework 2.0 and the OWASP Non-Human Identity Top 10 points toward reducing friction without weakening accountability, because governance only works when decisions are both fast and informed.

For NHI Management Group, the practical lesson is that access reviews fail when they are treated as an annual spreadsheet exercise rather than a continuous control. Teams should not ask managers to become security analysts. They should give them pre-filtered decisions, business context, and clear revoke paths so they can focus on exceptions, not inventory. That is especially important where shared service accounts, service principals, and API-driven access change faster than traditional certification cycles. In practice, many security teams encounter approval drift only after a review cycle has already normalized outdated access.

How It Works in Practice

The fastest way to reduce rubberstamping is to remove low-value review work before it reaches a human. Strong programs pre-populate review packets with last-used data, peer group comparisons, ownership, ticket references, and an expiry date for each entitlement. They also suppress obviously routine items when the risk is low and the entitlement is already tied to a current business function. This lets reviewers concentrate on exceptions, privileged access, and access that lacks a credible justification.

A mature process also shortens the path from decision to enforcement. If a reviewer marks access as unneeded, revocation should be automated or at least one click away. That is consistent with the lifecycle discipline described in the Ultimate Guide to NHIs and the control emphasis in Top 10 NHI Issues, where stale access and poor lifecycle handling repeatedly increase exposure. Reviewers should also see who approved the entitlement originally, whether the entitlement maps to a named application or owner, and whether the access is time bound.

• Group entitlements by role, application, and risk tier so reviewers assess patterns, not thousands of line items.
• Attach context such as last activity, ticket number, and business owner before the review starts.
• Use JIT or expiry-based access where possible so the review confirms continued need instead of permanent entitlement.
• Route only privileged, anomalous, or conflicting access to mandatory human approval.

This approach aligns well with the control expectations in NIST SP 800-53 Rev 5 Security and Privacy Controls, especially where organisations need evidence that access was reviewed, justified, and removed when no longer required. These controls tend to break down when entitlement data is fragmented across multiple systems and no single owner can reliably trigger revocation.

Common Variations and Edge Cases

Tighter review automation often increases engineering and governance overhead, requiring organisations to balance speed against the risk of hiding exceptions in the wrong queue. That tradeoff is real, especially in hybrid estates where application owners, IAM teams, and managers each control different parts of the access lifecycle. Best practice is evolving here: there is no universal standard for how much can be auto-approved, but there is broad agreement that low-risk, well-scoped entitlements should not consume the same reviewer attention as privileged or unexplained access.

Edge cases include emergency access, contractor access, inherited access through nested groups, and access granted through automated provisioning workflows. Those should not be forced into the same certification pattern as normal employee access. Emergency access should be separately logged and time limited. Contractor access should be tied to contract dates. Nested-group access should be expanded for visibility before review. Automated provisioning should be paired with periodic control testing so reviewers are not asked to rediscover system logic every cycle.

The strongest programs also publish clear rules for escalation. If a reviewer lacks enough context to make a decision, the item should route to the application owner, not sit unresolved until it is rubberstamped out of fatigue. That operating model is consistent with the governance intent in the Ultimate Guide to NHIs, especially where auditors expect a defensible trail rather than a pile of approvals. In practice, review quality drops most sharply when organisations optimise for completion metrics without also reducing entitlement complexity.
