Treat them as first-class governance exceptions, not as edge cases. Define who can approve access, how provisioning is executed, how verification happens, and how revocation is proven. If the application cannot participate in the normal lifecycle workflow, add compensating controls that close the loop on access state and accountability.
Why This Matters for Security Teams
Applications without a native IGA connector are not a tooling inconvenience, they are a governance gap. If access cannot flow through normal joiner-mover-leaver workflows, security teams lose reliable proof of who approved it, who provisioned it, whether it was actually applied, and whether it was later revoked. That breaks auditability, weakens least privilege, and often leaves orphaned access behind. Current guidance in NIST Cybersecurity Framework 2.0 still points to accountable access management, but for disconnected applications the control has to be built with compensating evidence rather than connector automation. NHI Management Group’s Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs frames this as a lifecycle problem, not a directory problem. In practice, many security teams encounter access sprawl only after an audit exception, privilege review failure, or offboarding incident has already exposed the lack of connector coverage.
When a platform cannot participate in the identity governance plane, the team should still force it into a documented control path. That means defining an approver, a provisioning method, a verification step, and a revocation test. The application is not exempt because it is awkward to integrate.
Strong programs also distinguish between workflow automation and control assurance. A manual ticket may be acceptable, but only if there is evidence that the change occurred, who made it, and how the result was checked. NHI governance usually fails when teams assume “approved” and “implemented” mean the same thing.
For broader context on lifecycle and control ownership, Top 10 NHI Issues highlights how unmanaged access and weak lifecycle discipline create recurring exposure across environments.
How It Works in Practice
The practical answer is to create an exception workflow that behaves like a governed access service, even when the target application has no connector. Security teams typically define a minimum control set:
- Named business and technical owners for the application and its accounts.
- Approved request paths for access creation, change, and revocation.
- Evidence requirements for provisioning, such as screenshots, API response logs, or admin audit trails.
- Periodic verification that the requested access still exists and still matches the approved purpose.
- Revocation testing, so removal is proven rather than assumed.
This aligns with the governance intent in Ultimate Guide to NHIs — Regulatory and Audit Perspectives: auditors care less about whether the application had a connector and more about whether the organisation can demonstrate control, ownership, and repeatability. If the application supports API-based administration, use that path for provisioning and deprovisioning before falling back to manual action. If it does not, a ticketing workflow plus independent verification is the baseline.
Teams should also align the exception with their broader identity controls from NIST Cybersecurity Framework 2.0, especially access control, logging, and governance functions. Where possible, attach compensating controls such as short-lived access, approval expiry dates, and explicit re-certification dates. Manual does not have to mean uncontrolled, but it does mean the control owner must prove every step.
These controls tend to break down when the application has shared admin accounts, no audit log export, and no reliable way to confirm that access removal actually took effect.
Common Variations and Edge Cases
Tighter exception governance often increases operational overhead, so organisations have to balance access speed against verification depth. That tradeoff is unavoidable when the application cannot join the normal IGA lifecycle.
Some edge cases need different treatment. Vendor-managed SaaS tools may require delegated administration, while legacy on-prem systems may only support OS-level or database-level account controls. In those cases, current guidance suggests governing the real access surface, not just the application login. If the privilege actually lives in a backend service account, that service account becomes the governance object.
Another common gap is temporary access. If teams issue access for troubleshooting or break-glass use, the exception should have an expiry, an owner, and a post-use review. Otherwise, temporary access becomes standing access by default. For organisations with large application portfolios, the best practice is evolving toward tiered governance: high-risk apps get full manual evidence and re-certification, while low-risk apps may use lighter checks if compensating logging is strong.
Where no connector exists and no reliable admin evidence is available, the honest answer is to treat the application as a high-risk exception until the vendor improves its integration model. The control objective is not perfect automation, it is provable accountability.
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-02 | Manual app governance prevents orphaned non-human access and weak lifecycle control. |
| NIST CSF 2.0 | PR.AC-4 | Access approvals and revocation proof map directly to governed access enforcement. |
