If your team is constantly jumping between apps just to get basic work done, you might be dealing with app overload. What starts as a few helpful tools can quickly turn into a mess of disconnected systems, shadow IT, and serious security risks.
In a recent episode of Stimulus Tech Talk, Stimulus Technologies founder and CEO Nathan Whittacre dug into how app overload happens, why disconnected tech systems are so dangerous, and what business leaders can do about it.
“Most companies have dozens of applications that often are bought over time,” Nathan explains. “For businesses, this adds up to tens of thousands of dollars, even per month—and we may or may not be using those together or correctly anymore.”
That’s not just wasted budget. It’s a growing attack surface for cybercriminals and a major source of confusion inside your organization.
How App Overload Happens in Growing Businesses
Very few companies set out to create a tangled tech stack. Instead, app overload creeps in slowly:
- A manager brings in a tool they loved at a previous job.
- A department signs up for a “quick fix” SaaS app to solve a specific problem.
- Employees grab free or low-cost software to make their own jobs easier.
Over time, you end up with:
- Multiple tools doing the same thing
- Data scattered across different platforms
- No clear answer when numbers don’t match
Nathan points out that this pattern is especially common in SMBs and fast-growing organizations. It can be a sign of growth—but without a plan, it becomes a drag on productivity and a real cybersecurity concern.
Why Integration and a “Source of Truth” Matter
Not every system needs to be tightly integrated, but your business does need a clear idea of how data flows and where the source of truth lives.
Nathan recommends deciding which application is the master record—often an ERP or primary line-of-business system—and building around that:
“You have to ask yourself where the real data is and what’s the source of truth as you’re adding on these other systems.”
When you don’t do this, disconnected tech systems create:
- Double entry and manual work
- Conflicting data between systems
- More errors and miscommunication
- Difficulty scaling or automating processes
In some cases, you may intentionally keep systems separate—for example, keeping prospects in your CRM and only pushing customers into your ERP. The key is that this separation is a strategic choice, not an accident.
The New Risk: AI, Shadow IT and Data Exposure
Disconnected systems used to be mostly a productivity problem. With AI and modern integrations, they’re now a major security problem as well.
Many AI tools and SaaS apps can plug directly into:
- Microsoft 365
- SharePoint and OneDrive
- Teams
- CRMs and ERPs
That power comes with risk. When users connect personal or unvetted AI tools to corporate data, you can lose control very quickly.
Nathan shares a realistic scenario: someone creates a custom AI bot and connects it to financial data in SharePoint to “make reporting easier.” If that bot is then shared widely—or worse, made available outside the organization—confidential information could be exposed to people who should never see it.
“You have to be really careful about data security, especially when you’re dealing with AI, because it does have the ability to pull all that data in,” Nathan warns.
For highly regulated industries, such as healthcare, this isn’t just risky—it may violate HIPAA or other compliance requirements.
Policies, Protection and Visibility
So what can you do to get app overload, shadow IT and AI risk under control?
Nathan recommends addressing it from both a policy and technology perspective.
1. Define clear, enforceable policies
- Create an acceptable use policy that spells out what employees can and cannot connect to company systems.
- Add a specific AI use policy that explains where company data is allowed to be used—and where it is not.
- Make sure employees know that new apps and integrations must go through an approval process.
2. Back policies with the right tools
- Control which apps are allowed to connect to Microsoft 365 and other core systems.
- Use monitoring and identity protection tools to spot unusual or risky application connections.
- Require IT or your technology service provider to review new software and AI tools before they’re integrated with company data.
“First, you’ve got to define what’s allowed in your acceptable use policy,” Nathan says, “and then have some enforcement that comes behind it with the technology solutions.”
