How should security teams govern credentials that live outside SSO and PAM?

Why This Matters for Security Teams

Credentials that live outside SSO and PAM are often the exact assets attackers target first because they bypass the central controls security teams trust most. These secrets may sit in application configs, CI/CD variables, cloud consoles, scripts, and vendor integrations, where they are easy to miss and hard to prove inactive. The risk is not just exposure, but persistence: once a token, key, or certificate is copied, it can survive long after the business need has changed.

This is why NHI governance has to treat secrets as managed identities, not one-off exceptions. NHIMG research on the Guide to the Secret Sprawl Challenge shows how unmanaged distribution creates blind spots across teams and environments. The industry consensus aligns with OWASP Non-Human Identity Top 10 and the NIST Cybersecurity Framework 2.0, both of which emphasise inventory, access control, and lifecycle discipline. In practice, many security teams discover secret abuse only after a leaked credential has already been used to move laterally or exfiltrate data.

How It Works in Practice

Governance starts by building a complete inventory of every credential outside SSO and PAM, including where it lives, which workload or user consumes it, who approved it, and what event should end its validity. That inventory should cover cloud access keys, service account secrets, API tokens, certificates, webhook credentials, and embedded secrets in code or pipelines. The next step is to assign an owner and a revocation path for each item so no credential exists without a named business purpose.

From there, teams should apply lifecycle controls that mirror the sensitivity of the workload. Current guidance suggests using short-lived credentials where possible, with rotation, expiration, and logging enforced at the storage location rather than only at the application layer. The Ultimate Guide to NHIs — Static vs Dynamic Secrets is useful here because static secrets create a larger recovery burden when they are copied into multiple environments. For implementation baselines, the NIST Cybersecurity Framework 2.0 and NIST SP 800-63 Digital Identity Guidelines reinforce proofing, authentication, and traceability, while NHIMG’s Top 10 NHI Issues highlights how rotation gaps and overprivilege compound each other.

• Use secrets scanning to find hard-coded credentials in repos, pipelines, and ticket attachments.
• Tag each credential with owner, purpose, and expiry so revocation is operational, not ad hoc.
• Prefer dynamic issuance or brokered access for systems that can tolerate it.
• Log creation, use, rotation, and revocation events in a way that can be audited later.

These controls tend to break down in legacy batch jobs, vendor-managed integrations, and embedded devices because the credentials cannot be rotated or reissued without downtime or code changes.

Common Variations and Edge Cases

Tighter secret governance often increases operational overhead, requiring organisations to balance faster rotation against application stability and support burden. That tradeoff is real, especially when credentials are shared across multiple services or when a third party controls part of the stack. There is no universal standard for every environment yet, so best practice is evolving toward risk-based treatment rather than one-size-fits-all rotation schedules.

For high-change environments, adopt shorter TTLs, stronger monitoring, and more frequent validation of who still needs access. For low-change or embedded environments, compensating controls may be necessary, such as segmentation, stricter vault access, and explicit renewal workflows. NHIMG’s Shai Hulud npm malware campaign illustrates how quickly exposed secrets can be harvested once they leave controlled storage, and the Cisco Active Directory credentials breach shows why access paths outside central IAM deserve the same scrutiny as privileged accounts. In these edge cases, the right answer is usually narrower scope, shorter life, and stronger detection rather than assuming the credential is acceptable because it is inconvenient to replace.
