They optimise for evidence at the end of the cycle instead of control throughout the cycle. That usually produces reports, not governance. Sustainable SAM requires operational triggers, clear owners and lifecycle events that happen before audit pressure arrives.
Why This Matters for Security Teams
When SAM is framed as an audit project, teams tend to collect evidence, then discover too late that the underlying control weaknesses never changed. That approach is especially risky for non-human identities because service accounts, API keys and automation tokens live inside systems that keep running after the audit closes. NHI Management Group’s Ultimate Guide to NHIs — Regulatory and Audit Perspectives shows why audit readiness must be tied to lifecycle control, not just documentation.
Good SAM is part of daily identity governance, aligned to operational controls such as ownership, expiry, rotation and revocation. That is closer to NIST Cybersecurity Framework 2.0 thinking than a one-time evidence exercise, because it treats identity risk as something to manage continuously. The practical failure mode is simple: if the team only proves that a record exists, it may still be possible for the associated secret to be stale, over-privileged or never removed after the workload changed. In NHI Management Group research, one of the clearest indicators of this gap is that only 20% of organisations have formal processes for offboarding and revoking API keys. In practice, many security teams encounter compromised or orphaned access only after an audit finding, incident or production change has already exposed the gap.
How It Works in Practice
SAM becomes sustainable when it is wired into the same systems that create and change access. Instead of waiting for an audit sample, teams should tie approval, provisioning, rotation and deprovisioning to lifecycle events such as application onboarding, ownership change, environment promotion, certificate expiry and service retirement. The operating model should answer four questions at all times: who owns the identity, what system uses it, what it can access, and when it must be reviewed or revoked.
That usually means separating evidence generation from control execution. Evidence can still be exported for auditors, but the control itself should live in policy, workflow and automation. The NHI Lifecycle Management Guide is useful here because it frames lifecycle events as governance triggers rather than cleanup tasks. For standards alignment, teams can map the program to the NIST Cybersecurity Framework 2.0 functions of Identify, Protect and Detect by making every identity record actionable.
- Assign an accountable owner to every service account, key and token.
- Define expiry, rotation and review intervals based on risk, not audit cadence.
- Require revocation when a workload, pipeline or vendor relationship ends.
- Use inventory reconciliation to find orphaned or unused identities before auditors do.
NHIs are not static assets, so the control model should not assume static behaviour either. NHI Management Group notes in its Ultimate Guide to NHIs — Key Challenges and Risks that 71% of NHIs are not rotated within recommended time frames, which is exactly the kind of operational drift that audit-only programs miss. These controls tend to break down when ownership is ambiguous across DevOps, platform and security teams because no single function feels responsible for timely change.
Common Variations and Edge Cases
Tighter lifecycle control often increases operational overhead, so organisations have to balance audit certainty against automation cost and application friction. That tradeoff becomes especially visible in legacy systems, shared service accounts and vendor-managed integrations, where full per-identity ownership may be hard to establish immediately.
Current guidance suggests prioritising the highest-risk identities first rather than trying to rebuild every entitlement at once. A practical sequence is to start with internet-facing services, privileged automation and credentials that never expire, then expand to lower-risk accounts. The Top 10 NHI Issues reinforces that poor visibility and excessive privilege are persistent drivers of SAM failure, not one-off exceptions.
There is no universal standard for every edge case yet, especially where a single identity supports multiple environments or where shared keys are embedded in CI/CD tooling. In those environments, best practice is evolving toward stronger segmentation, shorter-lived credentials and documented exceptions with expiry dates. The key is to avoid turning exceptions into permanent policy. If a control cannot trigger action when a workload changes, it is not real SAM governance, only audit evidence waiting to be collected.
Standards & Framework Alignment

OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0, 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 | GV.OC-01 | SAM needs clear ownership and accountability, not just audit evidence. |
| NIST CSF 2.0 | PR.AA-01 | Identity proofing and access control should be tied to active lifecycle events. |
| OWASP Non-Human Identity Top 10 | NHI-03 | Stale or unrotated secrets are a core SAM weakness in audit-only programs. |
| NIST AI RMF | SAM governance should account for lifecycle risk and continuous monitoring. |
