Who should own the gap between SSO, PAM, and unmanaged credentials?

Ownership should sit with identity governance, but execution must be shared with application, department, and security teams. The key is to make every credential accountable to a named business and technical owner, because no single tool can close the gap if the organisation has not defined responsibility for it.

Why This Matters for Security Teams

The gap between SSO, PAM, and unmanaged credentials is where accountability breaks down. SSO governs interactive users, PAM protects a subset of privileged access, and neither natively covers the long tail of service accounts, API keys, tokens, and certificates that power application-to-application work. When those credentials have no named owner, they become invisible risk, especially during incident response, cloud migrations, or app modernisation.

This is not just an access-control problem. It is an identity governance problem that spans business ownership, technical stewardship, and security oversight. Current guidance suggests treating every credential as a managed asset with an accountable owner, rather than assuming a tool stack will infer responsibility. The Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs and the OWASP Non-Human Identity Top 10 both reinforce that unmanaged NHI sprawl is a governance failure before it becomes a technical one.

NHIMG research shows the scale of the problem: 88.5% of organisations acknowledge their non-human IAM practices lag behind or are merely on par with human IAM, and 23.7% still share secrets through insecure methods such as email or messaging applications, according to the 2024 Non-Human Identity Security Report by Entro Security. In practice, many security teams encounter this gap only after a credential is exposed, rather than through intentional ownership design.

How It Works in Practice

Ownership should be assigned at the point a credential is created or discovered, not later during review. The business owner is responsible for why the credential exists, while the technical owner is responsible for how it is issued, rotated, monitored, and retired. Security or identity governance then sets the control standard, validates exceptions, and escalates risk when no owner can be identified.

Practically, that means building a credential inventory that includes service accounts, CI/CD secrets, API keys, OAuth tokens, certificates, and machine-to-machine trust relationships. Each record should map to an application, environment, and accountable team. Where possible, tie ownership to system-of-record metadata such as CMDB entries, cloud tags, repository references, or IAM directories. The goal is not only visibility but enforceable responsibility.

For teams modernising access, the best path is to reduce dependence on static secrets and move toward short-lived, just-in-time credentials. The Ultimate Guide to NHIs — Static vs Dynamic Secrets aligns with the broader direction in NIST Cybersecurity Framework 2.0, where asset accountability and risk treatment are central. For operational teams, this usually means:

• define one business owner and one technical owner for each credential class;
• require renewal, rotation, or re-approval on a fixed cadence;
• block orphaned credentials from remaining active beyond their service purpose;
• route exceptions through identity governance rather than informal team-level approval;
• measure ownership coverage alongside secret age, privilege, and exposure.

That model works best when application teams can update ownership metadata automatically and security can enforce policy through scanning and remediation workflows. These controls tend to break down in highly decentralised environments where secrets are created in pipelines, copied between teams, and never registered in a central inventory.

Common Variations and Edge Cases

Tighter ownership controls often increase operational overhead, requiring organisations to balance faster delivery against better accountability. That tradeoff is real, especially in cloud-native and developer-led environments where credentials are created frequently and discarded informally. Best practice is evolving, but there is no universal standard for this yet on exactly how ownership should be represented across every platform.

Some organisations place primary ownership with the application team, while others route it through identity governance or platform engineering. The practical answer depends on who can actually remediate a broken credential fastest. For shared services, the owner may be a platform team; for business applications, it is usually the product or service owner. For third-party integrations, the contract owner and the technical integrator may both need to sign off.

Edge cases include ephemeral CI/CD tokens, break-glass credentials, and inherited access in acquisitions. Those cases still need named accountability, even if the credential is short-lived or inherited. The Guide to the Secret Sprawl Challenge is useful here because it shows how quickly unmanaged credentials proliferate when no team is clearly accountable. For standards context, the control intent also maps cleanly to NIST SP 800-63 Digital Identity Guidelines and the governance emphasis in OWASP NHI guidance.
