Automated user access reviews: what changes for IAM teams?

TL;DR: Manual user access reviews remain a slow, error-prone snapshot process, while automated workflows can ingest identity data continuously, trigger context-driven certifications, and revoke access through downstream API calls according to Clarity Security. The real shift is from spreadsheet administration to continuous governance that reduces drift, audit friction, and standing access risk.

NHIMG editorial — based on content published by Clarity Security: automating user access reviews for IAM teams

By the numbers:

• 92% of organisations expose NHIs to third parties, raising concerns about supply chain security.
• Only 5.7% of organisations have full visibility into their service accounts.
• 80% of identity breaches involved compromised non-human identities such as service accounts and API keys.

Questions worth separating out

Q: What breaks when user access reviews stay spreadsheet-based?

A: Spreadsheet-based reviews break because they capture a stale snapshot, hide effective permissions, and rely on human follow-up for enforcement.

Q: When should organisations prioritise access review automation over manual certification?

A: Organisations should prioritise access review automation when entitlement volume, lifecycle churn, or audit pressure makes manual review unreliable.

Q: What do security teams get wrong about access review context?

A: Teams often assume more data solves the problem, when the real issue is comprehension.

Practitioner guidance

• Map the effective-permissions path for every high-risk identity Require your access review workflow to resolve nested groups, inherited access, and indirect entitlements before a manager sees the certification item.
• Trigger reviews from lifecycle events, not just calendar dates Use mover, joiner, and leaver events to launch targeted certifications when the risk state changes.
• Translate technical entitlements into business language Present reviewers with plain-language access descriptions such as read/write financial records, not raw group names or directory objects.
