Accountability should sit with a clearly named owner, even if several teams execute parts of the work. Larger organisations often place this under IAM or cybersecurity, while smaller teams may combine it with IT leadership and compliance. The key is cross-functional governance, because inventory, rotation, detection, and audit readiness all depend on shared control.
Why This Matters for Security Teams
When NHI risk is shared across security, IT, and compliance, the failure mode is usually not lack of effort. It is ambiguity. Credentials get created, rotated, logged, and audited by different groups, but no single owner is accountable when an API key, token, or service account is over-privileged or left exposed. Current guidance from NIST Cybersecurity Framework 2.0 and NHIMG’s own research on Top 10 NHI Issues points to the same practical need: clear governance, named ownership, and measurable control outcomes.
This is especially important because NHI risk is cross-functional by design. IT may provision the workload, security may monitor exposure, and compliance may need evidence for audit, but none of those roles alone can ensure lifecycle discipline end to end. The organisation needs a single accountable owner who can force decisions on inventory, rotation, exception handling, and remediation timelines. In practice, many security teams encounter NHI sprawl only after an incident, a failed audit, or a third-party integration review has already exposed the gap.
How It Works in Practice
Accountability works best when one function owns the policy and the operating model, while other teams execute defined parts of the process. In larger organisations, that owner is often IAM, cybersecurity, or platform security; in smaller organisations, it may sit with IT leadership, with compliance acting as a control verifier rather than a co-owner. The important point is that ownership must be explicit, documented, and tied to outcomes. Frameworks such as NIST SP 800-53 Rev. 5 Security and Privacy Controls and ISO/IEC 27001:2022 Information Security Management both support this model through defined control ownership, evidence collection, and ongoing review.
In operational terms, the accountable owner should be able to answer five questions at any time: what NHIs exist, who approved them, where secrets are stored, how access is reviewed, and what happens when an exception is found. That owner does not need to perform every task, but they do need authority to demand completion. NHIMG’s Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs is useful here because it frames NHI governance as a lifecycle discipline, not a one-time inventory exercise. The same logic appears in the vendor-neutral guidance from ISO/IEC 27002:2022 Information Security Controls, where controls are only effective when ownership, monitoring, and corrective action are assigned.
- Assign one accountable owner for the programme, not one per team.
- Document RACI boundaries for provisioning, rotation, detection, and audit evidence.
- Make compliance the reviewer of control effectiveness, not the substitute owner.
- Track exceptions with expiry dates and named approvers.
These controls tend to break down in federated organisations with many autonomous product teams because local tooling, shadow service accounts, and inconsistent exception handling quickly outrun central oversight.
Common Variations and Edge Cases
Tighter accountability often increases coordination overhead, requiring organisations to balance speed of delivery against control consistency. That tradeoff is real, especially when platform engineering, application teams, and governance functions all believe they own part of the NHI lifecycle. Current guidance suggests the best answer is not shared accountability in the abstract, but a clearly named primary owner with delegated responsibilities and escalation paths.
There is no universal standard for this yet, but mature programmes usually separate operational execution from governance accountability. For example, IT may own provisioning, security may own detection engineering, and compliance may own evidence standards, while one executive sponsor owns the programme risk. NHIMG’s Ultimate Guide to NHIs — Regulatory and Audit Perspectives is relevant because audit teams rarely accept diffuse ownership when a control gap surfaces. When organisations need a broader maturity benchmark, The State of Non-Human Identity Security shows why this matters: only 1.5 out of 10 organisations are highly confident in securing NHIs, which usually reflects governance confusion as much as technical weakness.
For regulated environments, the accountable owner should also understand how NHI risk maps to third-party access, audit evidence, and incident response. In highly distributed estates, the role may sit in cybersecurity but report through risk management so that remediation deadlines, policy exceptions, and board reporting are enforceable.
