Start with duplicated function, then compare identity complexity. The better consolidation candidate is the application that creates the most separate admin roles, access paths, and renewal exceptions, because those hidden governance costs often exceed the subscription line item.
Why This Matters for Security Teams
Consolidating SaaS tools is not only a cost exercise. Every overlapping application also brings its own admin model, SCIM integration quirks, renewal workflow, audit trail, and exception handling path. That identity sprawl creates hidden operational drag and increases the chance that secrets, service accounts, or delegated access linger long after a tool stops being strategically useful. NHI Management Group notes that 97% of NHIs carry excessive privileges, which is exactly why tool sprawl should be judged through governance friction, not just license count, as described in the Ultimate Guide to Non-Human Identities.
Security teams often focus on feature overlap and miss the fact that a “cheaper” SaaS platform may require multiple role mappings, separate token rotations, and custom offboarding logic. That is how consolidation decisions become security decisions. The NIST Cybersecurity Framework 2.0 is useful here because it treats governance, access control, and resilience as part of the same operating model, not isolated tasks. In practice, many security teams discover the real cost of SaaS sprawl only after an access review, incident, or renewal exception has already exposed the mismatch between business ownership and identity control.
How It Works in Practice
The practical test is to compare each SaaS tool on duplicated function and identity complexity. If two products solve the same business problem, the better consolidation candidate is usually the one with more hidden NHI overhead: more privileged roles, more API keys, more delegated admin paths, more manual reviews, and more fragile offboarding. A clean procurement scorecard should include both functional fit and control burden.
Teams usually get better results when they assess tools across a few concrete questions:
- How many separate admin roles are required to operate the platform safely?
- How many service accounts, OAuth apps, or API tokens are needed for normal use?
- Can access be provisioned and revoked centrally through SSO and SCIM, or does each team manage exceptions manually?
- How often are credentials rotated, and what breaks when they are?
- Does the tool create reusable access paths that outlive the original business need?
This approach aligns with common identity governance guidance because the real risk is not just who uses the SaaS product, but what non-human access it creates. NHIMG research shows how quickly delegated access can become an incident path in cases like the Salesloft OAuth token breach and the BeyondTrust API key breach, where access mechanisms themselves became the attack surface. A consolidation review should therefore include the number of standing secrets, the quality of offboarding, and whether the platform supports least privilege without custom exceptions. These controls tend to break down in highly federated environments where every business unit has its own admin owners, renewal cadence, and integration stack, because no single team has full visibility into the access paths that accumulate over time.
Common Variations and Edge Cases
Tighter consolidation often reduces cost but increases migration effort, so organisations need to balance subscription savings against data movement, user retraining, and control redesign. That tradeoff becomes sharper when the incumbent tool has already become a dependency hub for other systems.
There is no universal standard for SaaS consolidation scoring yet, so current guidance suggests using a weighted view rather than a single metric. Some tools should stay because they are deeply embedded in regulated workflows even if they are duplicative. Others should go because they create excessive identity complexity despite moderate business value. The hardest cases are platforms with strong feature depth but poor offboarding hygiene, since they can look efficient until the next audit or incident.
Teams should also treat shared integrations carefully. A SaaS application may appear redundant on its face, yet still be the only one that supports clean SSO, lifecycle automation, or centralized logging. In those cases, the right answer may be to keep the tool that reduces hidden NHI risk rather than the one with the lowest invoice. The same logic explains why breaches such as the Snowflake breach and the Sisense breach remain relevant to consolidation planning: once an access path is widely shared or poorly governed, removing the tool becomes only part of the remediation. In many enterprises, the true consolidation candidate is the platform whose access model is hardest to prove, not just the one that costs the most.
