Accountability should sit with the system or service owner, supported by identity and security teams that provide policy and enforcement. The important test is whether someone can prove the identity was retired or rotated when the business need ended, especially for third-party and automated access.
Why This Matters for Security Teams
nhi offboarding and rotation are not just administrative cleanup. They are the control points that determine whether a retired service, pipeline, integration, or vendor token can still act inside production. When accountability is unclear, teams often discover stale access only after an incident, audit finding, or failed cleanup. NHIMG’s NHI Lifecycle Management Guide treats lifecycle ownership as a core security function, not an optional hygiene task.
The practical issue is that NHIs rarely live in one system. They span app owners, cloud teams, DevOps pipelines, and third parties, while rotation requirements may be enforced by identity, secret, or platform tooling. The OWASP Non-Human Identity Top 10 highlights lifecycle failures as a major risk area because credentials that are never retired remain valid long after the business need ends. In the 2025 State of NHIs and Secrets in Cybersecurity, 91% of former employee tokens were still active after offboarding, which is a useful warning sign for broader lifecycle discipline.
In practice, many security teams encounter stale NHI access only after a service outage, vendor change, or breach has already exposed the gap.
How It Works in Practice
Accountability should rest with the system or service owner because that role has the clearest knowledge of business need, technical dependency, and retirement timing. Security and identity teams should define the control plane, but they should not be expected to guess when an integration is no longer needed. Best practice is to assign a named owner for each NHI, define the trigger for offboarding or rotation, and require evidence that the identity was revoked, replaced, or confirmed dormant.
Operationally, the process works best when it is tied to lifecycle events such as application decommissioning, vendor contract end dates, pipeline teardown, or access review findings. A strong workflow usually includes:
- an asset or service inventory that maps each NHI to a business owner
- rotation rules based on risk and credential type
- revocation steps for secrets, tokens, certificates, and API keys
- logging that proves who approved the change and when it completed
- backup checks to confirm the NHI is not reused by another workload
NHIMG’s Top 10 NHI Issues and Guide to the Secret Sprawl Challenge both point to the same failure mode: if secrets are duplicated or shared across teams, rotation and offboarding become partial, not complete. In implementation terms, teams should align this with guidance from the NIST Zero Trust Architecture and make revocation visible in the same systems used for access governance.
These controls tend to break down in shared platform environments where one service account supports multiple applications because no single owner can safely declare the identity ready for retirement.
Common Variations and Edge Cases
Tighter accountability often increases operational overhead, requiring organisations to balance clean ownership against the reality of shared services, outsourced operations, and rapid DevOps delivery. In mature environments, that tradeoff is usually worth it, but the ownership model has to reflect how the NHI is actually used.
There is no universal standard for this yet, but current guidance suggests three common patterns. For internally owned workloads, the application or service owner should own offboarding and rotation decisions. For platform-managed identities, the platform or SRE owner may execute the change, while the business owner remains accountable for the lifecycle decision. For third-party access, vendor management and security should require the contract owner or system owner to confirm retirement, because external integrations often survive long after the business case has ended.
The hardest edge case is emergency rotation. If a secret is suspected exposed, identity teams may rotate immediately, but the service owner still needs to validate downstream impact and confirm replacement credentials are working. That is why accountability and execution can be different roles, but they should never be different sources of truth. The Guide to NHI Rotation Challenges is especially relevant here, since rotation without dependency awareness can break production faster than a delayed change.
For organisations adopting more automated lifecycle controls, the Ultimate Guide to NHIs — Static vs Dynamic Secrets is a useful reference for deciding when short-lived credentials reduce offboarding risk. The reality is simple: ownership must be explicit before rotation can be reliable.
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 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-03 | Covers lifecycle and credential rotation failures for non-human identities. |
| NIST CSF 2.0 | PR.AC-1 | Access control governance depends on clear identity ownership and revocation. |
| NIST AI RMF | GOVERN | Accountability for automated entities requires defined governance and oversight. |
Assign each NHI an owner and verify rotation or retirement is completed and logged.
