Last quarter, I ran a comprehensive audit of our SaaS subscriptions. The results were worse than I expected. We found seventy-three applications that had been purchased departmentally, many with overlapping functionality and several that nobody was actively using.

The total annual cost of these shadow subscriptions was significant, but the real expense was hidden. Here’s what SaaS sprawl is actually costing your organisation.

The Direct Financial Waste

Let’s start with the obvious problem. We were spending over $200,000 annually on duplicate and unused SaaS applications. Marketing had three project management tools. Sales had two CRM systems plus Salesforce. HR had four different applicant tracking systems across regions.

Most of these were month-to-month or annual subscriptions that auto-renewed. Credit cards on file, nobody monitoring the charges. We found subscriptions for employees who’d left the company years ago. We found trial periods that converted to paid plans that nobody ever used.

The finance team was processing these payments dutifully, but without context about what the applications actually did or whether anyone was using them. Individual line items looked reasonable. The aggregate was shocking.

Security Risk Multiplies With Each Application

Every SaaS application is a potential entry point for attackers. Each one has its own authentication mechanism, permission model, and data handling practices. Our security team was trying to maintain oversight of the approved applications in our catalogue. They had no visibility into the shadow SaaS environment.

We discovered applications with weak password policies, no multifactor authentication, and admin accounts shared across entire teams. We found applications that had never been reviewed by our security team, never assessed for data handling compliance, and never included in our incident response planning.

When we finally ran a comprehensive security review across all discovered applications, we found several that posed unacceptable risks. Some had suffered data breaches we’d never been notified about because the subscription was tied to a personal email address, not our corporate domain.

Integration Debt Accumulates

Different departments were building integrations between their preferred tools and our core systems. Marketing automated data flows between three different analytics platforms. Sales had custom integrations feeding data into their secondary CRM.

These integrations were built by the departments themselves, often by that one technical person who knew how to write API scripts. Documentation was minimal or nonexistent. When that person left or moved to a different role, the integrations became black boxes.

We now had critical business processes dependent on undocumented, unsupported integrations between applications we didn’t know existed. The technical debt was substantial, and the risk of breakage was high.

Support and Training Costs Scale Poorly

Our help desk was fielding requests for dozens of applications they’d never heard of. When users had problems, they’d reach out to IT first. Our team would spend time troubleshooting before discovering the application wasn’t even in our approved catalogue.

Training was similarly fragmented. New employees in marketing needed to learn a different set of tools than new employees in sales, even when they were performing similar functions. We had no consistent onboarding experience and no way to measure training effectiveness.

The productivity cost of this fragmentation is hard to measure but definitely real. People spending time learning application-specific interfaces instead of focusing on their actual work.

Data Becomes Impossible to Govern

With data scattered across dozens of SaaS applications, our data governance efforts were crippled. Where was customer data actually stored? Which applications had access to financial information? How were we ensuring compliance with privacy regulations across all these platforms?

We couldn’t answer these questions with confidence. Our data governance policies applied to known, approved systems. The shadow SaaS environment was completely outside our governance framework. This created substantial compliance risk and made accurate reporting nearly impossible.

When we needed to respond to a data subject access request under privacy legislation, we had to scramble to identify which systems might contain relevant data. We almost certainly missed some.

How We’re Fixing It

We implemented a SaaS management platform that discovers applications through network traffic analysis and expense system integration. This gave us visibility into the full scope of the problem.

We established a lightweight approval process for new SaaS purchases. Departments can still move quickly, but IT and security get a chance to review for risks and duplicates. We’re not trying to say no to everything, just trying to make informed decisions.

For help with complex integrations, we worked with Team400, which helped us document critical data flows and build a proper integration architecture. They brought expertise in API design that our internal team lacked.

We also created a preferred application catalogue with pre-approved tools for common use cases. Need a project management tool? Here are three approved options with negotiated pricing and security review completed. This reduces the temptation to go shopping independently.

The Results So Far

Six months in, we’ve reduced our SaaS spending by about 30 percent by eliminating duplicates and unused subscriptions. We’ve improved our security posture by getting visibility into the full application landscape. We’ve reduced integration complexity by standardising on fewer tools.

More importantly, we’ve changed the culture. Departments now come to IT early in their evaluation process rather than after they’ve already purchased something. We’re partners in their technology decisions, not obstacles.

SaaS sprawl is inevitable in modern organisations. People need tools to do their work, and they’ll find them with or without IT approval. The answer isn’t to try to control everything. It’s to create visibility, establish lightweight governance, and make the approved path easier than the shadow path. That’s what actually works.
