How should organisations evaluate whether an extended access management approach is actually improving security?

Organisations should look for fewer unmanaged credentials, better visibility into where access lives, and stronger adoption of approved workflows. Useful signals include reduced password sharing, faster revocation, cleaner compliance evidence, and fewer exceptions for high-risk access. If controls are not changing daily behaviour, the programme is probably not working as intended.

Why This Matters for Security Teams

extended access management can reduce exposure, but it is only improving security if it changes where access exists, how long it lasts, and how quickly it can be removed. Security teams often mistake more policy coverage for better control, when the real test is whether privileged access becomes easier to find, harder to abuse, and faster to revoke. That is why control evaluation must focus on operational outcomes, not just deployment counts.

The current guidance in NIST Cybersecurity Framework 2.0 and the OWASP Non-Human Identity Top 10 points toward measurable governance, visibility, and least-privilege enforcement. NHIMG research reinforces the gap: in the State of Non-Human Identity Security, only 1.5 out of 10 organisations reported high confidence in securing NHIs, showing that many programmes still lack proof that access controls are working as intended.

In practice, many security teams discover that their access programme looks mature on paper only after an audit exception, a leaked secret, or a failed revocation exposes the control gap.

How It Works in Practice

To evaluate whether an extended access management approach is actually improving security, organisations should track control effects across the full access lifecycle: request, approval, issuance, use, revocation, and review. The important question is not whether access was “managed,” but whether the control reduced standing privilege, improved traceability, and shortened the time access remains usable.

A useful evaluation model combines evidence from identity systems, secret stores, and workload logs. For human access, check whether privileged sessions are becoming shorter, approvals are cleaner, and exceptions are declining. For machine and NHI access, check whether credentials are being rotated, secrets are stored centrally, and stale tokens are being retired quickly. NHIMG’s Ultimate Guide to NHIs notes that poor rotation and weak visibility remain major failure points, so a programme that does not reduce those conditions is not improving real security.

• Measure reduction in unmanaged credentials, not just total credentials enrolled.
• Track mean time to revoke access after role change, offboarding, or incident response.
• Compare the number of standing exceptions before and after rollout.
• Review whether audit evidence is generated automatically, not reconstructed manually.
• Validate that approvals map to actual entitlement use, not broad overprovisioning.

Security leaders should also compare control outcomes against the specific risks called out in the Top 10 NHI Issues, especially credential sprawl, weak rotation, and poor offboarding. If the programme is working, the environment should show fewer long-lived secrets, clearer ownership, and less reliance on manual exceptions. These controls tend to break down in highly automated CI/CD environments because access changes faster than review cycles and stale permissions accumulate between releases.

Common Variations and Edge Cases

Tighter access control often increases process overhead, so organisations have to balance stronger assurance against developer friction, operational speed, and support load. That tradeoff is real, especially where teams manage both human access and NHIs across cloud, SaaS, and pipeline tooling.

There is no universal standard for how quickly every entitlement must be revoked, but best practice is evolving toward context-aware review of high-risk access and shorter TTLs for sensitive secrets. In mature environments, the evaluation should include whether extended access management is reducing over-privileged accounts, improving third-party visibility, and making exceptions rare enough to be explainable. The NIST Cybersecurity Framework 2.0 and NIST SP 800-53 Rev 5 Security and Privacy Controls both support this outcome-based view, where control effectiveness is tied to measurable risk reduction.

One important edge case is automation-heavy organisations where secrets and entitlements are created and discarded continuously. In those environments, progress can be hidden if teams only look at quarterly reviews. The better indicator is whether runtime access is becoming more ephemeral and better governed over time. If exceptions remain high, revocation is slow, or access visibility still depends on manual spreadsheets, the programme is probably creating process, not security.
