Security teams should remove repeatable approval work from email and spreadsheet handling, then tie each access decision to identity context, entitlement state, and ownership. The goal is not just speed. It is to make every access change auditable, reviewable, and easier to defend when compliance or incident response asks why the access existed.
Why This Matters for Security Teams
Manual identity governance creates risk because the process itself becomes a control gap. Email threads, spreadsheet trackers, and informal approvers make it hard to prove who approved access, what entitlement changed, and whether the decision matched current ownership or business need. That is why current guidance increasingly treats governance as a traceable workflow problem, not just an access review problem. The NIST Cybersecurity Framework 2.0 reinforces accountability and repeatability, while NHIMG’s Regulatory and Audit Perspectives section shows why audit evidence matters when decisions are challenged later.
Security teams often assume manual review is acceptable if the reviewers are experienced. In practice, the failure mode is not just slow approvals. It is inconsistent decisions, missing context, and approvals that cannot be reconstructed after the fact. That becomes especially dangerous when privileged access, third-party accounts, or dormant accounts are involved, because a single missed review can persist far longer than the original business need.
NHIMG’s Top 10 NHI Issues highlights how governance weakness often sits alongside weak ownership and lifecycle discipline. In practice, many security teams encounter access sprawl only after an audit exception, incident, or termination event reveals that no one can explain why the entitlement existed.
How It Works in Practice
Reducing risk starts by removing repeatable approval work from inboxes and spreadsheets. Instead, access requests should flow through a governed workflow that records requester identity, resource owner, entitlement state, approval rationale, and expiration date in one system of record. This creates a reviewable decision trail and makes later recertification far easier. The NIST Cybersecurity Framework 2.0 supports this kind of repeatable governance because it emphasizes identifiable processes rather than ad hoc handling.
Practically, teams should connect three things at approval time:
- Identity context: who is requesting, who owns the account, and whether the account is human or non-human.
- Entitlement state: what access already exists, whether it is privileged, and whether it is still justified.
- Ownership and policy: who is accountable for the resource and what policy allows the change.
For NHI-heavy environments, this matters even more because manual governance often misses machine accounts, service identities, and OAuth-connected apps. NHIMG’s Lifecycle Processes for Managing NHIs is useful here because it ties governance to birth, use, review, rotation, and retirement rather than treating access as a one-time approval. Where automation is mature, current practice suggests using policy-as-code and routing rules to pre-classify low-risk requests, while escalating only exceptions to human review.
That approach also supports stronger evidence. Audit teams can verify the policy that applied at decision time, not just the final approval outcome. In practice, this reduces rework because reviewers are evaluating a structured request instead of reconstructing intent from fragmented messages. These controls tend to break down when entitlement data lives in separate tools and ownership is not maintained, because reviewers cannot reliably confirm what they are approving.
Common Variations and Edge Cases
Tighter governance often increases process overhead, so organisations have to balance speed against defensibility. Not every request should receive the same level of scrutiny, and best practice is evolving toward risk-tiered workflows rather than one universal approval path.
One common variation is temporary access. For low-risk, time-bound changes, current guidance suggests using shorter approval paths with automatic expiry, then requiring revalidation only if access is extended. Another edge case is emergency access, where a break-glass path may be justified but must still be logged, time-limited, and reviewed after the event. Manual approval is especially fragile in these cases because urgency encourages shortcuts.
Third-party and outsourced access needs extra care. Ownership may sit outside the organisation, but accountability does not. If approvers cannot identify the business owner, the access request should not move forward. NHIMG’s 52 NHI Breaches Analysis is a useful reminder that weak lifecycle discipline and poor visibility frequently show up together. The practical goal is not perfect elimination of manual review, but making sure manual steps only handle exceptions that the workflow cannot safely automate.
