Benchmark maturity by asking whether the programme can discover access, assign ownership, review it, and remove it across the full identity estate. A useful benchmark measures outcomes such as certification closure, revocation completion, and privileged access accountability. Tool coverage alone does not prove governance maturity if access can still persist outside review cycles.
Why This Matters for Security Teams
identity governance maturity is not measured by how many accounts a platform can ingest. It is measured by whether access can be discovered, owned, reviewed, and removed across human, service, machine, and vendor identities before exceptions turn into standing risk. That distinction matters because identity sprawl is where control gaps hide, especially in SaaS, cloud, and automation-heavy environments. NIST Cybersecurity Framework 2.0 provides the right orientation: outcomes, not tooling, define maturity.
NHIMG research shows the operational gap is still wide. In The State of Non-Human Identity Security, only 1.5 out of 10 organisations reported high confidence in securing NHIs, while the 2024 ESG report on non-human identities found that 72% of organisations have experienced or suspect an NHI breach. Those are maturity signals, not just incident statistics.
In practice, many security teams discover governance failures only after a dormant account, stale token, or unowned integration has already been abused rather than through intentional control testing.
How It Works in Practice
A useful maturity benchmark starts with the full identity estate, not only directory-managed users. That means measuring whether the programme can discover identities across IAM, SaaS, cloud workloads, CI/CD, APIs, service accounts, bots, and delegated third-party access. If discovery is incomplete, every later metric is distorted.
From there, benchmark the control lifecycle. A mature programme can show who owns each identity, what it is allowed to do, when access was last reviewed, and how quickly excess access is removed. Current guidance suggests treating these as outcome metrics:
- Discovery coverage across all identity classes
- Named ownership for each high-risk identity
- Certification completion and closure rates
- Revocation completion time after role change, task end, or decommissioning
- Privileged access accountability for break-glass, admin, and shared accounts
Use NIST Cybersecurity Framework 2.0 to organise those outcomes under Identify, Protect, Detect, Respond, and Recover. Then map them to lifecycle guidance in Ultimate Guide to NHIs, which emphasises that governance must follow the identity from creation through retirement. For NHI-heavy estates, benchmark separately for secrets rotation, token expiry, and ownership of machine-issued access because those controls behave differently from human access reviews.
A practical maturity scorecard should also test whether exceptions are time-bound, whether orphaned identities are automatically escalated, and whether reporting can prove not just coverage but closure. Tool coverage alone does not indicate maturity if a platform cannot enforce removal outside the review cycle. These controls tend to break down in highly federated organisations because ownership, provisioning, and revocation are split across multiple teams and systems.
Common Variations and Edge Cases
Tighter governance often increases operational overhead, requiring organisations to balance assurance against delivery speed. That tradeoff becomes visible in environments with DevOps autonomy, high API churn, or large partner ecosystems, where manual review cycles can lag behind real access changes.
Best practice is evolving for how to benchmark these edge cases. For cloud workloads and service identities, maturity is less about annual attestations and more about whether access is short-lived, automatically revoked, and tied to workload identity rather than a reusable secret. For third-party access, benchmark visibility into OAuth grants, delegated permissions, and vendor-owned service accounts. NHIMG notes that 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, which makes this a common blind spot.
Some environments also need separate maturity bands for privileged access, production automation, and emergency access. A mature programme should not force every identity into the same review cadence. Instead, it should classify identities by risk, enforce different revocation windows, and prove that high-impact access is continuously governed. Where that discipline is missing, certification completion rates can look healthy even while risky access persists between cycles.

Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0 and NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | ID.AM | Maturity benchmarking starts with complete identity asset discovery. |
| OWASP Non-Human Identity Top 10 | NHI-01 | Identity inventory and ownership are core to NHI governance maturity. |
| NIST AI RMF | GOVERN | Benchmarking needs accountable oversight, metrics, and control ownership. |
Measure identity coverage across the estate before scoring any downstream governance controls.
