How should IAM teams reduce recertification backlogs without weakening governance?

They should reduce campaign scope, improve entitlement data quality, and remove roles that no longer match real access patterns. The goal is not just faster approvals. It is making each review cycle precise enough that certifiers can make a current, defensible decision about access.

Why This Matters for Security Teams

Recertification backlogs are not just an efficiency problem. They are a control-quality problem. When review campaigns become too broad, too frequent, or too dependent on stale entitlement data, certifiers start approving by pattern rather than by evidence. That creates a false sense of governance while delaying the removal of access that no longer has a business need. The result is usually more risk, more rework, and less trust in the process.

NIST Cybersecurity Framework 2.0 treats access governance as an ongoing risk management activity, not a one-time administrative task, and NHIMG research on Lifecycle Processes for Managing NHIs makes the same practical point for non-human access: lifecycle precision matters more than campaign volume. The most effective IAM teams reduce backlog by improving the quality of what reviewers see, not by asking reviewers to make faster guesses. In practice, many security teams discover that a long recertification queue is already masking entitlement sprawl and role drift before the first escalation notice is sent.

How It Works in Practice

Backlog reduction works best when IAM teams shrink the review unit to something a certifier can actually validate. That usually means moving away from enterprise-wide campaigns and toward narrower reviews by application, role family, business unit, or risk tier. It also means removing entitlements that no longer map to real usage, because every stale role adds noise to the next cycle.

Current guidance suggests three practical changes:

• Reduce scope by reviewing only high-risk access first, then expand after the queue is under control.
• Improve entitlement metadata so each item shows owner, business purpose, last use, and system context.
• Use role mining and access analytics to retire roles that no longer reflect actual access patterns.

For non-human identities, the same logic applies but with more urgency. NHIMG’s Top 10 NHI Issues highlights that over-privilege and poor lifecycle control are recurring drivers of exposure, and the 2024 Non-Human Identity Security Report notes that 88.5% of organisations say their non-human IAM practices lag behind or only match human IAM. That is a warning sign that blanket review campaigns are often compensating for weak inventory, weak ownership, and weak rotation discipline. NIST Cybersecurity Framework 2.0 can help teams map review cadence to governance outcomes, while audit-facing teams can use Regulatory and Audit Perspectives to justify why a smaller, better-defined campaign is more defensible than a broad one.

These controls tend to break down in large hybrid estates with incomplete identity source data, because certifiers cannot reliably distinguish unused access from access that simply lacks telemetry.

Common Variations and Edge Cases

Tighter scoping often increases up-front analysis work, so organisations have to balance backlog reduction against the effort needed to clean entitlement data and redesign roles. That tradeoff is worth making, but it is not free.

There is no universal standard for campaign size, so maturity matters. Highly regulated environments may need more frequent reviews for privileged or sensitive access, while lower-risk access can move to exception-based review or longer review intervals. Best practice is evolving toward risk-based certification, where the queue is prioritised by privilege, sensitivity, and recent use rather than treated as one uniform workload.

Edge cases usually appear when the access model is already unstable. Shared accounts, inconsistent naming, orphaned entitlements, and overlapping role definitions all create false positives that inflate backlog without improving governance. In those environments, the right answer is often to pause expansion, clean the identity data, and retire the noisiest roles before the next campaign. For teams managing service and workload access, What are Non-Human Identities is a useful anchor for distinguishing human review logic from NHI lifecycle control, especially where secrets and tokens are involved. If the access catalogue is inaccurate or ownership is unclear, recertification queues will keep growing even when approval rates look healthy.
