How can IT and IAM teams reduce SaaS sprawl without slowing the business?

Why This Matters for Security Teams

saas sprawl is not just a cost problem. Every new application creates another identity surface, another consent path, another set of secrets, and another offboarding burden for IT and IAM. When ownership is vague, duplicate tools accumulate and access reviews become performative instead of effective. NIST Cybersecurity Framework 2.0 frames this as a governance and asset-management issue, not a one-time cleanup exercise.

The security risk is that unused or redundant SaaS often retains active integrations, service accounts, and delegated permissions long after the business has moved on. That creates persistence for attackers and hidden operational coupling for the business. NHIMG research also shows how often identity risk is underestimated: in the 2024 Non-Human Identity Security Report, 88.5% of organisations said their non-human IAM practices lag behind or merely match their human IAM maturity.

For teams trying to reduce SaaS sprawl without slowing delivery, the real task is to make software removal routine, evidence-based, and low-friction. In practice, many security teams discover the hardest app to retire is the one that still has a valid token, a forgotten owner, and an invisible dependency chain.

How It Works in Practice

The most effective approach is to treat SaaS rationalisation as an identity and lifecycle control, not just a procurement exercise. Start with a canonical inventory of apps, then group tools by function so duplicate products can be compared on actual usage, support burden, and access complexity. Ownership needs to be explicit: every SaaS app should have a business owner, an IT owner, and a revocation path for accounts, API keys, and OAuth grants.

This matters because redundant apps often keep running through delegated access, automation accounts, and stale integrations even after users stop logging in. The Ultimate Guide to NHIs — Key Challenges and Risks notes that 97% of NHIs carry excessive privileges and only 20% of organisations have formal offboarding and revocation processes for API keys. That makes software retirement a direct NHI control point, not a soft hygiene task. Where possible, pair app review with centralised consent management, secrets inventory, and log-based usage signals so teams can distinguish real demand from historical drift.

• Use usage telemetry to identify dormant or overlapping tools before renegotiating licenses.
• Require a named owner and a documented offboarding checklist for each app.
• Review service accounts, OAuth consents, and API keys as part of decommissioning.
• Prefer short-lived access and revocable tokens for integrations that must remain.

For high-risk integrations, NIST CSF 2.0 and access governance should be paired with credential hygiene. NHIMG case material such as the Salesloft OAuth token breach shows how third-party access can persist beyond the business need if revocation is not tightly managed. These controls tend to break down in environments with decentralised app purchasing and shadow IT because no single team can see the full dependency chain.

Common Variations and Edge Cases

Tighter SaaS governance often increases review overhead, so organisations need to balance speed of adoption against the cost of uncontrolled duplication. The best practice is evolving toward lighter-weight approval for low-risk tools and stronger review for apps that hold data, integrate deeply, or mint credentials. That avoids forcing every request through the same slow path.

There is no universal standard for SaaS rationalisation maturity yet, but current guidance suggests a tiered model: low-risk productivity tools can be fast-tracked, while finance, HR, customer data, and admin platforms need stricter ownership, logging, and offboarding controls. The NIST Cybersecurity Framework 2.0 supports this kind of risk-based governance, and the same logic applies to cloud-connected SaaS.

Edge cases appear when a duplicate app is technically redundant but operationally embedded in a workflow, or when one business unit relies on a niche tool that central IT barely sees. In those cases, reduction should be staged: freeze new sign-ups, migrate integrations first, then retire user access once dependencies are cleared. That approach preserves business continuity while still shrinking the attack surface. Teams that skip the dependency review usually find the real sprawl only after an integration breaks or an audit exposes unowned access.
