Ownership should sit with the identity governance function, with clear input from application, infrastructure, and security teams. If no single function can prove who approves, reviews, and revokes access for each non-human identity, then accountability is already split and control gaps are likely to persist.
Why This Matters for Security Teams
When identity platforms expand across engineering, cloud, DevOps, and application teams, NHI ownership often becomes the gap between policy and control. Service accounts, API keys, certificates, and tokens are easy to create but hard to assign clear accountability for across teams. That is why governance cannot be treated as a background platform function. It needs an owning function that can define approval, review, rotation, and revocation decisions consistently.
The risk shows up in scale and ambiguity. NHIs outnumber human identities by 25x to 50x in modern enterprises, and the Ultimate Guide to NHIs notes that only 5.7% of organisations have full visibility into their service accounts. In that environment, “shared ownership” usually means no one is accountable when credentials linger, are over-permissioned, or are never decommissioned. Security teams also need a governance model that aligns with broader control objectives in the NIST Cybersecurity Framework 2.0, especially around access control, asset visibility, and risk management.
In practice, many security teams only discover the ownership problem after an audit finding, a leaked secret, or a production incident has already exposed the absence of a clear approval path.
How It Works in Practice
Ownership should sit with the identity governance function because it is the only team positioned to define policy once and apply it across all NHI types. That does not mean identity governance acts alone. Application teams know usage context, infrastructure teams know deployment patterns, and security teams know risk tolerance. The governance owner translates that input into enforced lifecycle rules for provisioning, exception handling, review, and offboarding.
A practical model usually has three layers. First, identity governance sets policy for who can approve an NHI, what evidence is required, and when reviews must occur. Second, platform teams implement the technical controls, such as secret issuance workflows, certificate rotation, and revocation hooks. Third, application owners attest to business need and validate that each NHI still maps to a current workload or integration. The Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs is useful here because it frames NHI governance as a lifecycle, not a one-time onboarding exercise.
In mature environments, this ownership model is supported by a formal inventory, expiration dates, and an explicit approver chain. Current guidance suggests treating NHI ownership like any other control with evidence: who approved it, what it accesses, how long it lives, and who can revoke it. Mapping this operating model to the NIST Cybersecurity Framework 2.0 helps keep the discussion grounded in governance, detection, and recovery rather than platform convenience. It also aligns with the NHI management principle that access without revocation authority is not ownership. These controls tend to break down when multiple teams can create secrets independently, because no single function can enforce review or retirement at the point of use.
Common Variations and Edge Cases
Tighter central ownership often increases process overhead, requiring organisations to balance governance consistency against delivery speed. That tradeoff becomes most visible in federated platform models, where product teams want autonomy but still rely on shared identity infrastructure.
There is no universal standard for this yet, but best practice is evolving toward a federated operating model: identity governance owns the control framework, while local teams provide delegated approval and technical implementation. This is especially important where CI/CD pipelines, third-party integrations, and cloud-native workloads create large volumes of short-lived credentials. The Top 10 NHI Issues highlights that weak visibility and excessive privileges are recurring failure points, which is why ownership needs enforcement authority, not just advisory influence.
One common edge case is M&A or shared-services environments, where identity platforms span multiple business units with different approval norms. Another is regulated environments where audit evidence must show who owns the exception, not just who created the secret. In both cases, organisations should document a single accountable owner for the control, even if execution is distributed. The governance model fails when “platform team owns the tooling” is mistaken for “platform team owns the NHI risk.”
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 CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Ownership and accountability are foundational to NHI governance. |
| NIST CSF 2.0 | GV.OV-01 | Clarifies who governs cybersecurity outcomes across shared teams. |
| CSA MAESTRO | GOV-01 | MAESTRO emphasizes clear governance for agent and workload identities. |
Assign one accountable owner per NHI control domain and enforce approval, review, and revocation responsibility.
