Security teams should use identity discovery to find accounts and access paths that are missing from the PAM inventory, then pass that context into the existing review queue. The goal is to extend visibility, not replace control. Keep vaulting, rotation, onboarding, and approval decisions inside the PAM program so governance stays consistent while unmanaged privilege is surfaced and assessed.
Why This Matters for Security Teams
Hidden privileged identities are a control gap, not just an inventory problem. If service accounts, API keys, automation tokens, and vendor-created access paths are missing from PAM, then review, rotation, and approval workflows cannot protect them. That leaves teams with blind spots in the very places attackers and over-permissioned automation tend to exploit, as reflected in the Ultimate Guide to NHIs and the OWASP Non-Human Identity Top 10.
NHIMG research shows that only 5.7% of organisations have full visibility into their service accounts, and 97% of NHIs carry excessive privileges. Those figures matter because PAM works best when the inventory is complete and the control plane is consistent. The objective is not to create a second privilege system, but to surface unmanaged identities into the same governance model that already handles vaulting, rotation, and approvals. In practice, many security teams encounter the breach before they ever complete the discovery exercise, rather than through intentional control coverage.
How It Works in Practice
The safest pattern is to treat discovery as an intake layer for PAM, not as a replacement for it. Teams first identify hidden privileged identities across cloud accounts, CI/CD systems, SaaS apps, endpoints, and infrastructure automation, then classify each finding by owner, privilege level, rotation state, and business function. That context is passed into the existing PAM review queue so approvers can decide whether the identity should be vaulted, rotated, re-owned, or retired.
This approach aligns with the governance model described in the State of Non-Human Identity Security, where visibility gaps and over-privileged accounts remain common. It also matches current guidance in the OWASP Non-Human Identity Top 10: discovery, ownership, secret hygiene, and lifecycle control are all part of the same risk chain.
- Map every discovered identity to an owner and a system of record before any remediation decision.
- Preserve current PAM workflows for onboarding, vaulting, rotation, approval, and attestation.
- Prioritise privileged identities with standing access, long-lived secrets, or no clear business owner.
- Feed discovery results into ticketing or review queues so remediation is auditable and repeatable.
Where possible, use evidence from secret scanners, cloud IAM logs, and workload inventories to distinguish legitimate automation from abandoned access. This is especially important when identities are embedded in code, scripts, or pipeline variables, because those cases often evade human-centric review paths. These controls tend to break down when discovery cannot reliably attribute ownership in multi-account cloud estates and shared CI/CD platforms because the review queue fills with ambiguous findings.
Common Variations and Edge Cases
Tighter discovery and review often increases operational overhead, requiring organisations to balance faster exposure of hidden privilege against false positives and workflow fatigue. That tradeoff is real, especially when legacy systems, managed service accounts, or third-party integrations cannot be safely rotated on a standard cycle. In those cases, current guidance suggests documenting exception handling inside the PAM program rather than bypassing it.
One common edge case is an identity that is technically privileged but operationally embedded in a critical service. Another is a vendor account that is hidden from central inventory but still needs just enough access to function. In both situations, the control objective is the same: keep the identity visible, owned, and reviewable. The Ultimate Guide to NHIs — Standards is useful here because it reinforces that lifecycle governance and Zero Trust-style visibility should extend to non-human access, not sit beside it.
Best practice is evolving, but the safest operational rule is simple: do not allow newly discovered privilege to remain outside PAM just because it was not there at onboarding. If an identity cannot enter the standard workflow immediately, it should enter an exception track with explicit expiry, owner sign-off, and compensating control. That keeps hidden privilege from becoming permanently unmanaged.
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, OWASP Agentic AI Top 10 and CSA MAESTRO 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 |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Discovery and inventory gaps are central to hidden privileged identities. |
| OWASP Agentic AI Top 10 | Autonomous workloads often create hidden privilege outside normal human processes. | |
| CSA MAESTRO | IAM-02 | MAESTRO addresses identity governance for agentic and automated workloads. |
| NIST CSF 2.0 | PR.AC-1 | Identity management must cover all privileged accounts, including unknown ones. |
| NIST AI RMF | GOVERN | Governance is needed to assign accountability for unmanaged AI and automation access. |
Apply runtime identity governance so hidden automation is reviewed before it gains standing access.
