Yes. Integrations, service accounts, and automation tokens often depend on the same SaaS relationship as human users, so they must be covered in renewal, termination, and offboarding planning. Otherwise, machine access can survive after user access has been revoked.
Why SaaS Contract Reviews Must Cover Non-Human Identities
SaaS contracts are not just about named employees. They also define how integrations authenticate, what happens to connected apps when a subscription ends, and whether tokens, service accounts, or delegated access remain valid. If contract review ignores those mechanics, organisations can lose control of machine access even when human access has been formally terminated.
That matters because SaaS is often the control point for both business function and security boundary. A contract that says nothing about non-human identities can leave renewal, termination, export, and offboarding responsibilities unclear, which creates avoidable exposure at the moment the vendor relationship changes.
What to Check in Renewal, Termination, and Offboarding Clauses
Start by treating integrations as first-class assets in the agreement. The contract should reflect who owns the connection, how access is revoked, what evidence of deletion or disablement is provided, and whether the vendor supports token invalidation, connector removal, or scoped access review. NHIMG’s Service Account Security Guide is useful here because the same lifecycle issues apply when a SaaS app depends on service accounts or integration users.
Also verify the practical offboarding path, not just the legal wording. If a SaaS application is replaced, suspended, or terminated, you want a clear decision on whether the customer or the vendor is responsible for revoking API keys, rotating shared secrets, and disabling OAuth grants. The SaaS-to-SaaS and OAuth App Governance Guide is a strong companion because many SaaS dependencies are really consent and token-governance problems in contract form.
Finally, check whether the contract distinguishes human access from machine access in the service exit plan. If only employee accounts are covered, the organisation may believe it has offboarded the relationship while background automation still reaches the tenant, mailbox, or data store.
Where the Risk Shows Up in Practice
The main risk is residual access. A terminated SaaS relationship can still leave behind active tokens, long-lived credentials, connected apps, or background jobs that continue to authenticate after business owners think the vendor is gone. That can create data exposure, unauthorized transactions, or shadow dependencies that are hard to detect during a normal vendor review.
There is also a governance risk. If no one is explicitly accountable for non-human access in the contract, ownership often fragments between procurement, legal, security, and application teams. NHIMG’s NHI Ownership and Accountability Guide is relevant because orphaned access usually persists where ownership is unclear, not where the technical control is absent.
One more failure mode is scope drift. Teams may review the SaaS license count and forget the adjacent automation layer: sync jobs, webhooks, bot accounts, CI/CD hooks, and customer support integrations. Those dependencies may not be visible in the commercial contract unless they are explicitly named.
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 and OWASP API Security Top 10 address the attack and risk surface, while NIST CSF 2.0 sets the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 — Improper Offboarding | SaaS exit clauses must revoke non-human access and connected tokens. |
| NHI-07 — Long-Lived Secrets | Contract review should address tokens and credentials that outlive the SaaS relationship. | |
| NHI-05 — Overprivileged NHI | Integrated SaaS accounts and automation often exceed the access needed for the service. | |
| Recommendation — Require documented revocation of all non-human access during SaaS offboarding. Set expiry and rotation expectations for SaaS-issued secrets and tokens. Limit SaaS-connected identities to the minimum scopes needed. | ||
| OWASP API Security Top 10 | API2 — Broken Authentication | Many SaaS integrations rely on API and token authentication that must be revoked cleanly. |
| Recommendation — Validate how API and token authentication is disabled at contract end. | ||
| NIST CSF 2.0 | PR.AA-05 — Identity Management, Authentication, and Access Control | The question concerns access governance for human and non-human SaaS access. |
| Recommendation — Extend access control reviews to all SaaS-connected identities. | ||
Practitioner Guidance
What to prioritise: Treat every SaaS renewal or termination as both a commercial event and an access-revocation event. If the vendor relationship changes, assume that any connected credential or delegated app must be reviewed before the contract is signed, renewed, or exited.
What to verify: Confirm that the contract or offboarding runbook answers four questions: who owns the integration, how access is revoked, how the vendor proves revocation, and what happens to tokens or secrets that were issued outside the normal user lifecycle. If any one of those is vague, the review is incomplete.
Common mistake: Reviewing only named-user seats and ignoring non-human access because it is “technical” rather than contractual. In practice, the contract is often the only place where revocation responsibility is made explicit enough to enforce.
Practitioner takeaway: If a SaaS service can authenticate on your behalf, it belongs in the contract review on the same day as human access, because offboarding is only complete when both are removed.
