TL;DR: Orphaned accounts, outdated authorisation concepts, and AI-assisted recertification are presented by Nexis as practical IAM hygiene issues that can be improved in weeks rather than through a full transformation. The core message is that governance debt accumulates when access data, documentation, and review processes are not kept continuously current.
NHIMG editorial — based on content published by Nexis: IAM enhancing IAM hygiene and the hidden risks you can fix this quarter
Questions worth separating out
Q: Why do orphaned accounts remain a major IAM risk?
A: Orphaned accounts remain risky because access often outlives the business reason for it.
Q: Why do static authorization documents create governance risk?
A: Static documents become risky because they cannot reflect entitlement changes quickly enough to support actual access control.
Q: How do explainable AI recommendations help access reviews?
A: Explainable AI helps by flagging anomalies, prioritising high-risk entitlements, and giving reviewers a reason for each recommendation.
Practitioner guidance
- Identify and retire orphaned accounts Run a cross-system inventory that correlates directory records, HR leavers, and SaaS accounts, then verify ownership for every active identity before the next review cycle.
- Convert authorization concepts into live control artefacts Move role, entitlement, and rule documentation into a maintained system of record so changes are reflected in access reviews, audit evidence, and governance reporting.
- Use explainable AI for review prioritisation Limit AI to recommending anomalies, likely revocations, and data-quality issues, then require human reviewers to approve changes with a recorded rationale.

IAM hygiene is often the easiest place for attackers and auditors to find governance debt. Orphaned accounts, stale permissions, and out-of-date authorization concepts are not edge cases. They are symptoms of identity programmes that still rely on periodic cleanup instead of continuous lifecycle control. The practitioner lesson is that hygiene work is not housekeeping, it is exposure reduction.
A question worth separating out:
Q: What should organisations prioritise first in IAM hygiene work?
A: Organisations should first remove inactive access that no longer has a clear owner, then update the authorization model so it reflects current system reality. After that, they can use AI to accelerate reviews and improve prioritisation. Fixing drift at the source has more value than layering analysis on top of stale data.
