They often treat non-human identities as technical plumbing rather than governed identities. That leads to stale access, unclear ownership, and weak offboarding when applications or vendors change. The result is privilege that persists long after the original purpose has ended.
Why This Matters for Security Teams
Privileged Access Management is often built around human workflows, yet non-human identities do not request access, change roles, or leave the organisation on a predictable schedule. That mismatch is why PAM controls that work for administrators can fail for service accounts, API keys, pipelines, and application secrets. NHI Management Group research shows that 97% of NHIs carry excessive privileges, which turns a control meant to reduce risk into a storage layer for standing access. See the Ultimate Guide to NHIs and the NIST Cybersecurity Framework 2.0 for the governance lens that PAM programs need.
The common mistake is to treat PAM as a vault problem instead of an identity governance problem. If ownership is unclear, rotation is inconsistent, and offboarding is not tied to application or vendor lifecycle events, privilege persists long after the business need ends. That creates blind spots in audit evidence, incident response, and third-party risk management. In practice, many security teams discover NHI privilege sprawl only after a breach, a failed rotation, or a vendor exit exposes how much access was never truly governed.
How It Works in Practice
For NHIs, PAM should manage the full identity lifecycle, not just secret storage. That means knowing what the identity is, who owns it, what it can access, when it was last rotated, and when it must be revoked. Static roles are often too coarse for machine workloads because applications and automations follow event-driven patterns rather than stable human job functions. Current guidance suggests pairing PAM with workload identity, policy enforcement, and automated secret rotation so access is granted only when the workload is running and the task is legitimate.
In mature environments, PAM for NHIs usually includes:
- Inventory of service accounts, API keys, certificates, tokens, and CI/CD secrets.
- Business ownership and technical ownership assigned to each identity.
- Short-lived credentials and rotation tied to usage, not calendar convenience.
- Revocation workflows connected to decommissioning, vendor termination, and pipeline changes.
- Continuous review of effective permissions, not just vault presence.
That approach aligns with the governance intent behind NIST CSF, but it also needs practical evidence from real incidents. NHI Management Group documents how secret exposure often persists in repositories and automation systems, as illustrated by the JetBrains GitHub plugin token exposure and the BeyondTrust API key breach. Those cases show that secrets are rarely lost in one place only; they spread across code, config, and tooling. PAM that cannot follow those dependencies breaks down when credentials are embedded in build systems, third-party integrations, or service meshes because revocation becomes operationally risky and incomplete.
Common Variations and Edge Cases
Tighter PAM often increases operational overhead, requiring organisations to balance stronger control against deployment speed and application stability. That tradeoff is real for legacy systems, shared service accounts, and third-party managed integrations where rotating a secret can break production if dependencies are not mapped first. Guidance is still evolving on how aggressively to replace long-lived machine credentials with ephemeral issuance in every environment, so best practice is to start with the highest-risk identities rather than force a universal pattern.
Common edge cases include break-glass accounts, embedded secrets in older applications, and vendor-owned automations. These often need compensating controls such as tighter monitoring, segmented access, and documented exception expiry dates. PAM also tends to fail when teams assume a vault alone equals governance. A stored credential is not a controlled identity if nobody can answer who owns it, what it protects, or when it should be removed. Organisations should treat those exceptions as temporary risk decisions, not permanent architecture.
Where PAM programs for NHIs most often fall short is in environments with rapid CI/CD churn and shared infrastructure, because the identity changes faster than the review and revocation process can keep up.
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 and CSA MAESTRO address the attack and risk surface, while NIST AI RMF set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-03 | Rotation and lifecycle control are central to PAM misuse for NHIs. |
| CSA MAESTRO | M2 | Agent and workload governance requires identity lifecycle controls beyond vaulting. |
| NIST AI RMF | Governance and accountability are needed when automated systems use privileged access. |
Assign accountability for machine privilege decisions and review them continuously.
