TL;DR: Opal Security says Access Comparison is generally available, letting IAM teams compare any two users side by side and surface standing, unused, overprivileged, and irregular access so they can remediate with reviews, expiration dates, or permission removal. Least privilege is becoming a continuous comparison problem, not a quarterly certification exercise.
Editorial analysis by NHI Mgmt Group, based on content published by Opal Security: “New in Opal: Access Comparison, Find and Fix Outlier Access Fast”.
Key questions
Q: What breaks when access reviews are only run on a fixed schedule?
A: Fixed-cycle reviews encourage repetition, not judgment.
Q: Why does comparing users help identify least privilege failures?
A: Comparing users exposes entitlement differences that are hard to spot in isolated records, especially when groups, roles, and application permissions are spread across systems.
Q: How do teams decide whether access is actually justified over time?
A: By tying certification, role design, and revocation to business purpose, not just successful authentication.
Practitioner guidance
- Prioritise outlier access cases Build your governance queue around users whose access materially differs from peers in the same role, team, or application context.
- Convert permanent access to time-bound access Where comparison shows no durable business need, replace standing entitlements with expiration dates so access ends when the task or assignment ends.
- Trigger user access reviews on mismatches Use the comparison result as evidence for a targeted user access review instead of a broad periodic campaign.
Bottom line: The core governance problem is not whether access has been reviewed before, but whether it still matches the role, task, or peer baseline now.

Continuous access comparison is a governance control, not a convenience feature. The real value is that it converts access review from a periodic attestation into a live question about entitlement legitimacy. That matters in programmes where standing privilege, inherited access, and role drift are the norm rather than the exception. Practitioners should treat comparison as a way to test whether least privilege is still true in operation.
A few things that frame the scale:
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems. Organisations failing to scope AI access properly are 4.5x more likely to experience a security incident, according to the 2026 Infrastructure Identity Survey.
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Should IAM teams focus on access review or access optimisation?
A: They need both, but the order matters. Review verifies whether access was ever acceptable, while optimisation continuously reduces access that no longer fits the role or task. In mature programmes, review becomes a targeted response to outlier access rather than the primary governance mechanism.
