Teams should compare current login activity, last-use timestamps, and business ownership against the paid entitlement. If the app is not used, the owner cannot justify the seat, or the entitlement survives a mover or leaver event, the license is not defensible and should be reclaimed or downgraded.
Why This Matters for Security Teams
SaaS license need is not just a procurement question; it is an identity and access question. A seat that remains assigned after the user stops logging in, changes role, or leaves the business becomes dead spend at best and an unmanaged access path at worst. Current guidance in NIST Cybersecurity Framework 2.0 pushes teams toward continuous governance, which is the right mindset here: entitlement decisions should reflect actual use, business ownership, and risk, not assumptions made at purchase time.
The same logic shows up in real breach investigations. When tenants or SaaS accounts remain active without clear ownership, attackers can abuse stale access, especially where OAuth grants, API keys, and service integrations are still trusted. NHIMG has documented how unmanaged non-human access becomes persistent attack surface in incidents such as the Salesloft OAuth token breach and the Snowflake breach. In practice, many security teams discover a license was never really needed only after renewal has already locked in the spend and the stale access has already widened the blast radius.
How It Works in Practice
Teams know a SaaS license is actually needed by testing for three conditions at the same time: recent use, identifiable business ownership, and a current operational reason to keep the entitlement. If one of those is missing, the license is usually a reclaim or downgrade candidate. The most reliable approach is to treat each seat like a governed entitlement rather than a static asset.
A practical review usually combines:
- Login and activity telemetry, including last-use timestamps and feature-level usage where the vendor exposes it.
- Manager or application owner attestation that the user still needs the paid tier.
- Lifecycle checks for mover, leaver, contractor expiry, and team reorg events.
- Comparison of the paid tier against the minimum access required to do the job.
This is where entitlement hygiene intersects with broader NHI governance. A license that exists to support an integration, automation, or delegated workflow should be validated like any other non-human access path, not exempted because it is packaged as SaaS. NHIMG research shows why this matters: only 5.7% of organisations have full visibility into their service accounts, and that same visibility gap often affects SaaS seats tied to scripts, bots, and shared operational mailboxes. The broader lesson aligns with the Ultimate Guide to NHIs: if the organisation cannot explain who or what is using access, it cannot defend the entitlement.
In operational terms, teams should build a reclaim workflow that flags unused or unjustified licenses, routes them for owner confirmation, and removes or downgrades them before renewal. Where the application supports it, usage-based tiering is preferable to blanket enterprise assignment because it keeps procurement tied to evidence. These controls tend to break down when the SaaS app is shared across departments and the vendor only exposes coarse tenant-level usage data, because the business owner cannot prove which specific seat is actually needed.
Common Variations and Edge Cases
Tighter license control often increases review overhead, requiring organisations to balance savings against administrative friction. That tradeoff is real, especially in fast-moving environments where people temporarily need premium features for one project and then no longer need them.
There is also no universal standard for this yet. Current guidance suggests treating these cases differently:
- Shared team licenses may be justified if the work is seasonal or bursty, but they still need an owner and a refresh cadence.
- Power users may appear inactive in login logs while still being legitimate if they use offline exports, API-driven workflows, or SCIM-managed automation.
- Contractors and vendors should be revalidated more aggressively because their need is often time-bound.
- Licenses attached to service accounts, bots, or OAuth integrations should be reviewed as access entitlements, not employee perks.
For teams trying to separate real need from stale assignment, the safest pattern is to combine usage data with business attestation and expiration logic, then revisit the seat on a fixed schedule. That approach is more defensible than assuming every purchased license remains necessary until renewal. NHIMG case studies like the BeyondTrust API key breach and the Dropbox Sign breach show how stale access paths linger long after their original purpose has faded.
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 |
|---|---|---|
| NIST CSF 2.0 | PR.AC-4 | Access rights should match current business need and actual use. |
| OWASP Non-Human Identity Top 10 | NHI-02 | Stale SaaS access mirrors unmanaged non-human entitlement sprawl. |
| NIST AI RMF | Governance requires ongoing monitoring of use and accountability. |
Review SaaS entitlements regularly and remove or downgrade seats that no longer support an active business function.
