They often confuse tool adoption with control coverage. A strong IdP, PAM, or IGA stack does not guarantee that every application is enforcing the same controls. Maturity must be measured by real enforcement, continuous drift detection, and evidence that local identity paths are governed.
Why Organisations Misread IAM Maturity
IAM maturity is often judged by platform adoption rather than by what is actually enforced at the application, workload, and secret level. A mature-looking stack can still leave local accounts, stale API keys, and bypass paths untouched. That is why NHI Management Group emphasises governance evidence, not product count, in its Ultimate Guide to NHIs. The same pattern appears in enterprise control frameworks such as NIST SP 800-53 Rev 5 Security and Privacy Controls, which focus on operational control implementation, not just tooling.
The practical problem is that identity programs get measured on centralised coverage while risk accumulates in exceptions: legacy applications, machine accounts, CI/CD secrets, partner integrations, and cloud-native services. In those areas, the question is not whether an IdP exists, but whether every access path is bound to policy, logged, rotated, and revoked. NHIs often outnumber human identities by 25x to 50x in modern enterprises, so even small gaps scale quickly. In practice, many security teams encounter maturity failures only after a leaked secret or privilege escalation has already exposed the local control gap, rather than through intentional testing.
How Maturity Should Be Measured in Practice
Real IAM maturity is visible in enforcement consistency. A strong program proves that access decisions, credential lifecycle rules, and revocation logic work across all identity types, not only through the primary IdP. That includes service accounts, workload identities, tokens, certificates, and application-local accounts. Current guidance from NIST and NHI practitioners suggests assessing controls by evidence: can the team show who has access, why it exists, how long it lasts, and whether it is removed on time?
For non-human identities, the operational questions are sharper because secrets and permissions tend to spread. The Azure Key Vault privilege escalation exposure case illustrates how a control can appear sound centrally while still allowing privilege growth through adjacent roles and mis-scoped permissions. A mature IAM program therefore needs continuous drift detection, secrets inventory, automated rotation, and evidence that local identity paths are governed. That is especially important when organisations still store long-term credentials in code or rely on manual revocation. In one recent NHIMG research finding, 88.5% of organisations said their non-human IAM practices lag behind or are only on par with human IAM, which shows how common this measurement gap remains.
Practically, teams should validate maturity with questions like:
- Are all application and workload identities mapped to an owner and a purpose?
- Are credentials short-lived where possible, and revoked automatically when the task ends?
- Are local accounts and shadow access paths discovered, monitored, and reduced?
- Can auditors trace enforcement evidence across cloud, SaaS, CI/CD, and legacy systems?
These controls tend to break down in hybrid environments with embedded secrets and independently managed application stacks because the enforcement model fragments across too many administrative domains.
Where the Maturity Model Breaks Down
Tighter governance often increases operational overhead, requiring organisations to balance visibility against deployment friction. That tradeoff becomes real when teams try to apply a uniform maturity score to very different identity surfaces. A zero-trust policy for workforce access is not the same thing as governance for ephemeral workload credentials, and neither is equivalent to partner API access. Best practice is evolving, but there is no universal standard for treating every identity path as if it followed the same lifecycle.
One common mistake is treating exceptions as temporary when they are actually structural. If a legacy system cannot integrate with the central IAM stack, the organisation still needs compensating controls, but maturity should not be overstated simply because the exception is documented. Another mistake is assuming that audit pass equals control health. An access review can look complete while stale secrets remain valid for days, as NHIMG research has shown in secret-remediation lag. That is why evidence must include actual revocation timing, drift alerts, and failed-access tests, not just policy documents.
For modern identity programs, the question is not whether IAM tools exist. It is whether the organisation can prove that identity controls are enforced where risk is created, especially in applications and workloads that never touch the main console. In practice, many teams discover that gap after a credential leak or privilege escalation, not during the maturity assessment itself.
