Unused licenses often indicate more than wasted spend. They can signal orphaned access, poor offboarding, duplicate tools, or incomplete ownership records. IAM and governance teams should use license utilisation as an evidence source for access review, because persistent underuse often means the entitlement model no longer matches how the application is actually used.
Why This Matters for Security Teams
Unused SaaS licenses are not just a procurement cleanup item. For IAM and governance teams, they are often an early signal that identity data, access decisions, and application ownership are out of sync. A license that sits idle may belong to a terminated user, a contractor who was never fully removed, or a duplicate entitlement that was granted outside normal workflow. Current guidance suggests treating utilisation as an access signal, not only a cost metric.
This matters because SaaS estates are frequently the place where orphaned access hides. A license can remain assigned long after the business owner has changed, and the access review may still pass if the record only checks whether the account exists. NHIMG’s Ultimate Guide to NHIs — Regulatory and Audit Perspectives frames this as a governance issue, while the NIST Cybersecurity Framework 2.0 pushes teams toward better asset, access, and continuous monitoring discipline. In practice, many security teams encounter license waste only after an audit finding, a renewal dispute, or an access incident has already exposed the control gap.
How It Works in Practice
The practical value of unused SaaS licenses comes from correlating three things: entitlement assignment, actual usage, and business ownership. If a user has been assigned a paid seat but has no recent activity, that should trigger an investigation, not an automatic assumption that the license is safe to keep. Teams should separate low-use cases from truly unused ones, then verify whether the account is dormant, shadow IT, or a shared login that should never have been licensed in the first place.
Strong programmes use licence utilisation as one input to joiner-mover-leaver controls, access recertification, and vendor risk review. That means security, IT, and procurement need a shared view of:
- Which identities are entitled to the application
- Which identities have actually used the application within the review window
- Whether the licence maps to an active employee, contractor, or service account
- Whether removal of the licence should also remove API tokens, admin roles, or connected OAuth grants
That last point is important because SaaS licensing and identity governance often diverge. A user may no longer need the seat, yet still hold linked access paths such as delegated tokens or app-specific permissions. NHIMG’s Top 10 NHI Issues is useful here because many “unused” licences are actually stale identity relationships, not just procurement inefficiencies. When organisations review these records alongside controls from frameworks such as NIST CSF and access governance policy, they usually uncover incomplete offboarding, duplicate subscriptions, or ownership drift. These controls tend to break down when SaaS administration is decentralised across business units because usage data, entitlement data, and approver data live in different systems.
Common Variations and Edge Cases
Tighter licence governance often increases operational overhead, requiring organisations to balance clean entitlement records against user experience and renewal pressure. A licence that appears unused may still be required for seasonal work, infrequent executive use, or emergency access, so there is no universal standard for this yet. Best practice is evolving toward risk-based thresholds rather than a single inactivity rule.
Edge cases matter. Shared accounts can distort utilisation metrics, automation accounts may appear idle by design, and some SaaS platforms only expose partial activity telemetry. In those environments, current guidance suggests combining licence utilisation with login history, role assignments, and owner attestation rather than making removal decisions from one metric alone. NHIMG’s Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs is especially relevant where licences are tied to service identities, integrations, or automated workflows. The operational rule is simple: if a licence is idle, it should be explained, revalidated, or removed, but not ignored.
Standards & Framework Alignment

OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0 and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | ID.AM-01 | Unused licenses expose mismatched asset and entitlement inventories. |
| NIST CSF 2.0 | PR.AA-01 | Idle licenses can signal stale or excessive access privileges. |
| OWASP Non-Human Identity Top 10 | NHI-03 | Stale SaaS access often reflects poor lifecycle and rotation discipline. |
