Teams should validate ownership, review who still has access, and fold the app into a rationalisation decision that includes entitlement cleanup and offboarding. The goal is not just to reduce spend. It is to eliminate orphaned access paths before they become long-lived governance blind spots.
Why This Matters for Security Teams
Duplicate or unused SaaS apps are rarely just a finance problem. They often indicate overlapping ownership, stale integrations, and forgotten admin paths that still reach sensitive data. When teams treat rationalisation as a licence cleanup exercise, they miss the more important risk: dormant access that was never fully inventoried or revoked. That is exactly how governance blind spots persist across the application stack, especially when multiple teams can create and approve SaaS tools independently. NIST’s Cybersecurity Framework 2.0 reinforces that visibility and access control are operational requirements, not optional hygiene.NHI Management Group’s Ultimate Guide to NHIs — Key Challenges and Risks notes that only 5.7% of organisations have full visibility into their service accounts, which is a useful signal for why unused apps often hide non-human access paths as well. In practice, many security teams uncover the real issue only after an offboarding event, an audit, or a breach reveals that the “unused” app still had valid tokens, delegated permissions, or privileged integrations.
How It Works in Practice
A sound response starts with ownership validation. Teams should confirm who approved the app, who uses it, what data it touches, and whether it is connected to service accounts, API keys, or delegated OAuth grants. Then the app should be classified into one of three outcomes: retire, consolidate, or retain with controls. The key is to make entitlement cleanup part of the decision, not a separate afterthought.The NHI Lifecycle Management Guide is relevant here because SaaS tools often act as identity and access brokers for both people and workloads. If an app is duplicated, the associated NHIs may also be duplicated, which creates parallel credential paths that outlive the business need. That is especially important for applications tied to CI/CD, ticketing, analytics, and collaboration platforms where access is granted through integrations rather than direct login.
Practical steps usually include:
- Identify all users, admins, service accounts, and external connectors.
- Check for active OAuth grants, API keys, tokens, and shared secrets.
- Reassign data ownership before decommissioning the app.
- Revoke unused entitlements and rotate any credentials tied to the app.
- Confirm offboarding with logs, not just application deletion.
Current guidance suggests that unused saas discovery should be paired with access review and NHI cleanup because deleting the subscription does not necessarily remove downstream permissions. That lesson is reinforced by real-world breaches such as the Snowflake breach, where credential exposure and weak lifecycle controls were central themes. These controls tend to break down in federated SaaS environments where business units manage their own apps and identity teams do not have authoritative visibility into every integration path.
Common Variations and Edge Cases
Tighter SaaS rationalisation often increases short-term operational overhead, requiring organisations to balance clean-up speed against business continuity. Some apps are “unused” only from the perspective of the original owner, while another team still depends on a hidden workflow, webhook, or shared mailbox. Others are duplicate in function but not in risk, because one instance may contain regulated data or privileged integrations that make immediate retirement unsafe.There is no universal standard for this yet, but best practice is evolving toward context-based decisions rather than simple duplication counts. That means preserving apps that have validated ownership and clean entitlements, while forcing remediation on apps with no accountable owner. The Top 10 NHI Issues is a useful reference when teams need to distinguish true lifecycle decay from ordinary application sprawl. For organisations with many third-party integrations, unused SaaS often becomes the place where orphaned tokens and over-privileged NHIs accumulate fastest, especially when the app is not formally offboarded. The safest decision is the one that removes access paths, not merely software licenses.
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 CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-03 | Duplicate apps often leave stale NHI credentials and unused access paths behind. |
| NIST CSF 2.0 | PR.AC-4 | Unused SaaS still requires access review and entitlement cleanup. |
| NIST CSF 2.0 | ID.AM-1 | Discovery depends on knowing which applications and assets are actually in use. |
