Accountability should sit with the system owner, the approving security team, and the identity governance function together. The marketplace is the distribution channel, not the control owner. Organisations should define who approves scope, who reviews ongoing use, and who must revoke access when the integration no longer fits the business need.
Why This Matters for Security Teams
Marketplace-delivered integrations often arrive with a trust signal that exceeds the actual control boundary. That is the risk: a marketplace can distribute an integration, but it cannot own the approval, scope, or lifecycle decisions that make the integration safe. In NHI governance, accountability must stay with the system owner and the functions that can actually constrain access, not with the storefront that advertised the app.
This matters because integrations frequently request broad API access, long-lived secrets, and permissions that outlast the business need. NHI Mgmt Group notes that 97% of NHIs carry excessive privileges, and 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, which shows how quickly a convenient integration can become an enterprise exposure. The governance lesson is reinforced in Ultimate Guide to NHIs — The NHI Market and in NIST Cybersecurity Framework 2.0, which both point toward explicit ownership and ongoing control.
In practice, many security teams encounter overreach only after an integration has already expanded data access or automated actions beyond the original approval.
How It Works in Practice
The practical answer is to treat marketplace integrations as third-party enabled NHIs with explicit ownership, scope, and revocation duties. The marketplace may publish metadata, reviews, or permissions prompts, but it does not replace internal governance. Security teams should require a named business owner, a technical owner, and an approving security function before any token, OAuth grant, service account, or API key is issued.
Operationally, the strongest pattern is to approve the integration at runtime against the exact scope requested, then continuously re-check whether that scope still matches the business use case. That aligns with the control logic in NIST CSF 2.0, especially identity and access oversight, and with NHI lifecycle guidance in Ultimate Guide to NHIs. Where possible, teams should prefer short-lived tokens, scoped OAuth grants, and just-in-time access over static secrets that persist after the original request is forgotten.
- Assign accountability to the system owner for use-case approval and business justification.
- Assign accountability to security for pre-approval, scope review, and exception handling.
- Assign accountability to identity governance for periodic recertification and revocation.
- Require logging that shows which integration used which permissions, and when.
- Revoke access immediately when the integration no longer matches the approved need.
For marketplace-delivered tools, the key question is not whether the app was listed in an approved catalog, but whether the organisation can prove who accepted the risk and who can remove it. These controls tend to break down when integrations are installed by business users directly into SaaS platforms because the approval path, ownership record, and revocation workflow are often split across different teams.
Common Variations and Edge Cases
Tighter control over marketplace integrations often increases operational overhead, requiring organisations to balance faster adoption against stronger review and revocation discipline. That tradeoff becomes visible when low-risk productivity apps and high-risk data integrations are treated the same.
Current guidance suggests three common exceptions need special handling. First, self-service marketplaces inside a SaaS platform can still create enterprise-wide risk if a user grants access to shared data or production systems. Second, pre-approved vendor integrations may still overreach when product updates add new permissions without a fresh review. Third, delegated administration can blur ownership if the line-of-business team believes the vendor owns the risk, while security assumes the business owner does.
There is no universal standard for this yet, but best practice is evolving toward continuous approval instead of one-time approval. That means keeping an inventory of marketplace-installed integrations, mapping each one to an accountable owner, and rescinding standing access when the integration is idle, unverified, or no longer aligned to the business purpose. In NHI terms, the control objective is simple: distribution can be external, but authority must remain internal.
