TL;DR: Clarity Security says manual user access reviews still depend on spreadsheet aggregation, manager follow-up, and delayed revocation, which creates stale evidence, hidden errors, and access drift. The shift to automated reviews turns certification into a continuous control instead of a periodic administrative exercise.
At a glance
What this is: NHI Mgmt Group's analysis, drawing on Clarity Security's blog post: Automating user access reviews replaces spreadsheet-driven certification with continuous, context-aware remediation and audit-ready reporting.
Why it matters: IAM teams, IGA leads, and audit stakeholders need this shift because manual reviews create delay, error, and stale evidence that leave excess access in place.

Context
User access review is the process of checking whether people still need the access they already have. In the manual model, that work depends on spreadsheets, manager responses, and later cleanup, which means the review is often out of date before it ends.
The governance gap is not the review itself, but the lag between access change, reviewer decision, and actual revocation. For IAM and IGA programmes, that lag creates access drift, weak evidence, and unnecessary operational drag.
Clarity Security frames automation as a way to make access reviews continuous, context-driven, and easier to evidence for audit without changing the underlying governance obligation.
Key questions
Q: What breaks when user access reviews are still manual in hybrid environments?
A: Manual reviews break when reviewers cannot reliably see all active entitlements across cloud, on-prem, and third-party systems. The result is incomplete certification, stale access that survives role changes, and weak remediation evidence. In practice, the review process becomes too slow to reflect how quickly modern permissions drift.
Q: When should organisations move from manual recertification to automated access reviews?
A: Organisations should move as soon as manual recertification starts slowing down approvals, creating inconsistent decisions, or leaving too little time before audit deadlines. Automation is especially justified when the same users must be reviewed across SAP and multiple connected applications. At that point, workflow standardisation, risk scoring, and faster remediation materially improve control quality.
Q: Why do access reviews often fail to reduce privilege creep?
A: Access reviews fail when organisations do not have a complete and current picture of active identities and entitlements. If dormant accounts, shared credentials, or non-human identities are missing from the inventory, the review only validates part of the environment. In that case, privilege creep continues even though the process appears to have run.
Q: How should IAM teams govern access reviews across multiple systems?
A: They should define one accountable review owner, one evidence standard, and one remediation path that applies across every connected directory, SaaS platform, and on-prem system. If the review cannot trigger action in all downstream systems, it only measures governance. Consistency matters more than review volume.
Technical breakdown
How manual user access reviews break at scale
Traditional user access reviews turn identity governance into a document-handling exercise. Teams extract data from directories, HR systems, and SaaS platforms, merge mismatched files, distribute them for approval, and then reconcile responses by hand. Every transfer step introduces copy errors, stale data, and interpretation risk. The deeper problem is temporal: review evidence is a snapshot, while access is changing continuously. By the time the spreadsheet closes, the entitlement state may already have moved on. That gap explains why manual certification looks controlled but often fails to reflect effective access.
Practical implication: treat spreadsheet-based certification as a temporary control gap, not a durable review model.
Why automated access reviews improve governance context
Automated user access reviews replace batch handling with continuous ingestion and context-aware certification. Instead of forcing managers to interpret raw group names or nested permissions, the system normalises identity data, resolves inherited access, and presents reviewer-friendly labels. That matters because certification quality depends on whether the reviewer can understand what is actually being approved. When reviews are triggered by lifecycle events such as a mover change, governance becomes narrower and more relevant. The control is no longer just coverage, but decision quality based on current entitlement context.
Practical implication: expose effective permissions and business context before asking for approval, or reviewers will continue to rubber-stamp access.
How instant remediation changes the control loop
In a manual review, a revoke decision often becomes a ticket or follow-up task that is executed later, if at all. Automation closes that loop by connecting the review outcome directly to deprovisioning workflows through APIs or orchestration. That changes the risk profile because the control is no longer only diagnostic. It becomes corrective at the moment the decision is made. For IAM programmes, that is the difference between evidence generation and actual access reduction. It also strengthens audit posture because reviewer intent, action, and system change can be tied together in one flow.
Practical implication: connect certification decisions to immediate remediation so revocation is not separated from governance.
Threat narrative
Attacker objective: The practical objective for an attacker or insider is to keep unnecessary access alive long enough to expand misuse, delay detection, or preserve a foothold in the environment.
- Entry begins when identity data is manually exported from multiple systems and assembled into a spreadsheet, creating a stale review surface before certification even starts.
- Escalation occurs when managers rubber-stamp unclear entitlements or nested permissions because the review lacks business context and effective-access detail.
- Impact follows when unrevoked access persists across quarterly or annual cycles, leaving excess privilege, audit exposure, and license waste in place for months.

NHI Mgmt Group analysis
Manual access review is a governance lag problem, not a paperwork problem. The real failure is the delay between entitlement change, reviewer judgment, and enforced revocation. That delay turns certification into historical documentation rather than active control. For identity programmes, the meaningful question is whether review evidence still matches current access at the point of decision.
Effective permissions are the unit of review, not raw entitlements. Nested groups, inherited access, and cross-system identities make line-item review misleading if the reviewer cannot see what the identity can actually do. Clarity Security's topic reinforces a broader IAM truth: certification quality depends on resolving privilege before asking for approval. The practitioner implication is to review effective access, not directory noise.
Context is what separates governance from rubber-stamping. When reviewers see technical labels instead of business meaning, they approve by default to avoid interrupting work. Automated review flows that translate entitlements into human-readable access descriptions reduce that failure mode. In identity governance terms, this is a reviewer comprehension problem, not a reviewer discipline problem.
Audit readiness improves only when remediation and evidence are linked. A clean report means little if revocation still depends on separate tickets and manual follow-up. The control value comes from a closed loop that records who reviewed what, what changed, and when the system enforced the decision. Practitioners should treat that linkage as part of the control, not as an afterthought.
Continuous review is becoming the operating model for modern IAM. Quarterly campaigns cannot keep up with mover events, SaaS sprawl, and rapid entitlement change. The field is moving toward ongoing certification because static cycles create stale risk windows. Security teams should re-evaluate where periodic review still makes sense and where event-driven controls should take precedence.

What this signals
Continuous certification is becoming the practical answer to access drift. Quarterly review cycles cannot keep pace with role changes, inherited permissions, and SaaS sprawl. For IAM teams, the real programme choice is whether review remains a scheduled event or becomes part of the ongoing entitlement lifecycle.
Reviewer context determines whether governance is real or cosmetic. If a manager cannot translate a group name into business meaning, the control collapses into approval bias. Automated access reviews should therefore be judged by how well they surface effective permissions, not by how many emails they remove from the queue.
For practitioners
- Standardise review on effective permissions Resolve nested groups and inherited privileges before certification so reviewers assess what users can actually do, not just the top-level role label.
- Trigger micro-certifications on mover events Run targeted reviews when employees change roles or departments so carried-over access is reviewed while the entitlement context is still current.
- Connect revoke decisions to automated deprovisioning Treat revocation as a system action, not a follow-up task, so the review outcome changes the target account or permission immediately.
- Clean up orphaned and toxic access before automation Remove unowned accounts and separation-of-duties conflicts before increasing certification speed, or automation will accelerate bad governance.
Key takeaways
- Manual access reviews fail when collection, approval, and revocation are disconnected across too many handoffs.
- Automation improves control quality by showing effective permissions and tying review decisions to immediate enforcement.
- For IAM and IGA teams, the main benefit is not less work alone, but less time spent carrying stale privilege and stale evidence.

Key terms
- User Access Review: A user access review is a periodic check that confirms each account still needs the access it has. In identity programs, the control is used to reduce excess privilege, support compliance, and catch access that has outlived its business need.
- Effective Permissions: Effective permissions are the access an identity can actually use after role inheritance, scope, and policy are applied. In Azure AI environments, they often matter more than the assigned role name because inherited rights can widen access to data, logs, and secret stores.
- Answer Drift: Answer drift is the gradual change in a model’s responses over time, often showing up as reduced consistency or increasing error rates. It can signal degraded grounding, shifting data quality, or prompt and retrieval issues. Monitoring drift helps teams catch reliability problems before they become widespread user-facing failures.
- Micro-certification: Micro-certification is a narrow access review or approval step used to validate a specific entitlement, action, or risk signal. It reduces review scope compared with full recertification, but it still needs clear ownership and documented decision criteria to remain trustworthy.
