How should security teams use maturity benchmarks without creating false confidence?

Why This Matters for Security Teams

Maturity benchmarks are useful because they turn a vague programme discussion into a concrete gap assessment, but they are easy to misread as proof that controls are actually working. That confusion is common in NHI and access governance, where a scorecard can look healthy while long-lived secrets, unused entitlements, and third-party access remain unchanged. Benchmarks should therefore be treated as triage, not evidence.

The confidence gap is real. NHIMG research in The State of Non-Human Identity Security found that only 1.5 out of 10 organisations are highly confident in securing NHIs, even though many already have some form of programme in place. That gap matters because benchmark-led reporting can create a false sense of progress unless it is tied to live identity data, ownership, and verification. For baseline identity assurance concepts, teams can also compare their approach with NIST SP 800-63 Digital Identity Guidelines.

In practice, many security teams discover benchmark inflation only after an audit, incident, or access review reveals that the underlying entitlements never changed.

How It Works in Practice

A sound maturity process starts by separating measurement from control effectiveness. A benchmark can tell a team whether it has a secret inventory, rotation policy, ownership mapping, and monitoring process. It cannot tell the team whether those controls are enforced, current, or materially reducing risk. Current guidance suggests mapping each benchmark domain to a live signal: secret age, last rotation date, active service accounts, privileged entitlements, and vendor connections.

That is where the benchmark becomes operational. For example, if a programme scores well on credential rotation, the next question is whether rotation happens automatically, whether exceptions are tracked, and whether revoked credentials are still accepted downstream. NHIMG’s Ultimate Guide to NHIs — Key Research and Survey Results is useful here because it reinforces the scale of the maturity gap and shows why static reporting is not enough. The practical test is simple: if the benchmark cannot be tied to evidence in identity telemetry, it should not be treated as assurance.

• Assign each benchmark item to a control owner, not just a programme owner.
• Link every gap to a remediation action with a due date and a verification step.
• Validate against live access data, not screenshots or policy documents alone.
• Retest after changes to ensure entitlements, privilege, or data reach actually moved.

This approach aligns well with CISA Zero Trust Maturity Model thinking, because maturity is only meaningful when it results in measurable enforcement. These controls tend to break down when identity data is fragmented across clouds and SaaS platforms because the benchmark has no reliable way to verify what is still active.

Common Variations and Edge Cases

Tighter benchmarking often increases reporting overhead, so organisations have to balance comparative visibility against the risk of turning maturity into theatre. In mature environments, a benchmark may be useful for board reporting or prioritisation, while operational teams need something stricter: continuous verification of secret age, access scope, and revocation success.

There is no universal standard for this yet. Some teams score themselves against policy presence, others against control outcomes, and others against observed reduction in exposure. The best practice is evolving toward outcome-based maturity, where a higher score must correlate with less standing access, fewer stale secrets, and faster remediation. NHIMG’s Ultimate Guide to NHIs — Standards is a useful reference point when a team needs to distinguish between framework coverage and actual enforcement.

One common edge case is third-party access. A programme can look mature internally while still having limited visibility into OAuth apps, partner credentials, or delegated tokens. Another is M&A or multi-cloud sprawl, where benchmark scores lag reality because identity ownership is unclear. In those environments, the score should be treated as directional only, and control validation must be based on live entitlement and telemetry evidence.
