They should stop tying governance maturity to per-user licence models and focus on entitlement lifecycle, access review, and revocation for every identity type. Service accounts, API keys, and AI agents still require policy enforcement even when billing is based on compute or usage rather than seats.
Why This Matters for Security Teams
When SaaS pricing shifts from seat-based licensing to usage-based, compute-based, or event-based billing, many teams mistakenly assume NHI governance can be relaxed because the vendor no longer counts “users” the same way. That is a category error. Service accounts, API keys, CI/CD tokens, and AI agents still create access paths, still inherit privilege, and still need ownership, review, and revocation regardless of how the platform is sold. The governance problem is the identity lifecycle, not the invoice.
NHIs are already a dominant security surface, with NHI Mgmt Group reporting that NHIs outnumber human identities by 25x to 50x in modern enterprises in its Ultimate Guide to NHIs. That scale makes pricing changes dangerous if procurement signals are used as a proxy for risk. Security programs should anchor their controls to lifecycle and entitlement evidence, not to whether a vendor labels access as a seat, a workload, or a metered resource. The NIST Cybersecurity Framework 2.0 remains relevant here because it frames identity and access as continuous risk management, not a billing artifact. In practice, many security teams discover this gap only after an orphaned token or overprivileged service account is exploited, rather than through intentional governance.
How It Works in Practice
Governance should begin by classifying every non-human identity by function, owner, data access, and revocation path. Pricing changes do not alter those requirements. A metered SaaS app may remove the obvious “seat” concept, but it still depends on long-lived secrets, OAuth grants, and service-to-service trust chains that must be reviewed on a schedule. NHI Mgmt Group’s lifecycle guidance for managing NHIs is the practical anchor: assign an accountable owner, define the business purpose, record where the identity is used, and automate offboarding when the workload is retired.
For organisations adjusting to new SaaS pricing, the control model should shift from procurement-led inventory to entitlement-led governance:
- Maintain a complete register of service accounts, API keys, certificates, and agent credentials.
- Link each identity to a business service, human owner, and explicit approval path.
- Review entitlements on a fixed cadence, not only at contract renewal.
- Revoke or rotate credentials when the workload changes, not when billing changes.
- Use the same access review standard for NHIs as for privileged human access.
This matters because pricing models can obscure sprawl. A vendor may no longer expose “user count,” but your organisation can still accumulate dormant API keys, unmanaged OAuth apps, and service accounts with broad permissions. The most common failure mode is assuming that usage-based SaaS is naturally self-governing. It is not. NHI risks remain visible in real incidents such as the Snowflake breach and the BeyondTrust API key breach, where credential handling and entitlement scope mattered more than commercial packaging. These controls tend to break down when ownership is ambiguous across procurement, platform, and application teams because revocation authority becomes unclear.
Common Variations and Edge Cases
Tighter entitlement governance often increases operational overhead, requiring organisations to balance auditability against developer and platform-team speed. That tradeoff is real, especially when SaaS billing changes from seat-based to usage-based and teams fear extra process will slow adoption. Best practice is evolving, but there is no universal standard for how to map commercial pricing to NHI control ownership, so organisations should treat pricing as a finance input, not a governance boundary.
Two edge cases deserve special attention. First, embedded SaaS integrations can hide NHIs inside vendor-managed workflows, where access may not appear in traditional admin consoles. Second, AI-enabled SaaS features can create ephemeral or semi-autonomous identities that behave more like workloads than users. In those cases, the practical control is not “does this have a seat” but “can this identity be traced, reviewed, and revoked on demand.” NHI Mgmt Group’s regulatory and audit perspectives are useful when auditors ask for evidence that governance applies consistently across all identity types. Organisations should also monitor Top 10 NHI Issues for recurring failure patterns, especially around stale secrets and overprivileged accounts. The governance rule is simple: if the identity can act, it must be inventoried, owned, reviewed, and revocable, even when the SaaS bill no longer mentions users.
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-01 | Governance must inventory and own every non-human identity, not just billed users. |
| NIST CSF 2.0 | PR.AC-1 | Identity governance still requires access control regardless of SaaS pricing model. |
| NIST AI RMF | AI-enabled SaaS can introduce autonomous identities that need lifecycle oversight. |
