They treat catalogue support as the end of the governance problem. In reality, the catalogue only defines the initial boundary of visibility. The harder task is keeping every source accurate over time, especially where legacy apps, databases, and custom feeds do not fit standard integration patterns.
Why Security Teams Misread Connector Catalogues
Connector catalogues are often treated like a complete inventory, but they are really only a product boundary: what is supported, discoverable, and easy to onboard. That framing misses the operational problem, which is drift. The real risk sits outside the catalogue in legacy systems, custom feeds, shadow integrations, and permissions that change after the initial connection is approved.
This is why visibility gaps persist even after a platform is “covered.” NHI governance is still about the full lifecycle of credentials, entitlements, and revocation, not just whether an integration appears in a menu. NHIMG’s Ultimate Guide to NHIs notes that only 5.7% of organisations have full visibility into their service accounts, which shows how quickly catalogue confidence can outrun operational reality. The same pattern appears in broader identity programmes where tooling coverage is mistaken for control maturity.
Security teams also overestimate what “supported” means. A connector may authenticate successfully while still failing to surface effective privileges, secret sprawl, or stale access paths. In practice, many security teams encounter exposure only after a connector has already drifted out of policy, rather than through intentional governance reviews.
How Catalogue Governance Actually Works in Practice
Effective catalogue governance starts with treating the catalogue as a starting point for control mapping, not the control itself. Teams should maintain a source-of-truth register that links each connector to the real system owner, the credentials in use, the data touched, and the revocation path. That register needs periodic reconciliation against actual activity, because integration state changes faster than most review cycles.
Current guidance from NIST Cybersecurity Framework 2.0 supports this by emphasizing continuous identification, protection, detection, and response across assets and relationships. For catalogues, that means tracking not just which apps are present, but whether each connection still matches an approved business purpose, acceptable privilege set, and monitored ownership.
- Classify each connector by system type: SaaS, database, file transfer, custom API, or legacy batch job.
- Record the credential form used: API key, OAuth token, service account, certificate, or delegated admin path.
- Verify whether the catalogue reflects effective permissions or only the initial onboarding scope.
- Reconcile catalogue entries with logs, secret stores, and IAM records on a fixed cadence.
- Require explicit offboarding steps for connectors that are retired, replaced, or no longer monitored.
This is where NHIMG’s research on the State of Non-Human Identity Security is especially relevant: organisations often lack full visibility into third-party connections, which is exactly the kind of blind spot catalogue-only thinking leaves behind. The practical test is simple: can the team prove what is connected, why it is connected, and how it is removed when the business case ends?
These controls tend to break down in hybrid environments with custom integrations and unmanaged legacy services because ownership is unclear and telemetry is incomplete.
Common Failure Modes and Edge Cases
Tighter catalogue control often increases operational overhead, so teams must balance completeness against the cost of maintaining accurate metadata across many systems.
The hardest edge cases are the ones that do not fit neat connector templates. Legacy databases, bespoke ETL jobs, embedded scripts, and vendor-managed integrations may authenticate in ways the catalogue cannot fully describe. Best practice is evolving here, and there is no universal standard for how much metadata a catalogue must carry to be considered “governed.”
Two practical rules help reduce ambiguity. First, do not treat a connector as low risk simply because it is familiar or long-lived. Older integrations often have the least monitoring and the weakest revocation discipline. Second, avoid assuming that a connector catalogue can replace identity governance or secret management. A catalogue can name the integration, but it cannot prove rotation, effective privilege, or offboarding unless those controls are enforced elsewhere.
Security teams also need to watch for false confidence created by partial automation. A connector that auto-discovers new sources may still miss human-created exceptions, service accounts created outside standard workflows, or credentials embedded in scripts. The right operating model is continuous reconciliation, not one-time approval.
NHIMG’s Ultimate Guide to NHIs is useful here because it frames visibility, rotation, and offboarding as lifecycle issues rather than tooling features. That distinction matters most when catalogues become crowded with inherited integrations, where support status says little about whether the connection still belongs in production.

| OWASP Non-Human Identity Top 10 | NHI-01 | Connectors often hide unmanaged non-human identities and stale access paths. |
| NIST CSF 2.0 | ID.AM-01 | Catalogue accuracy is an asset inventory problem, not just a tooling problem. |
