Modern businesses run on connected apps. Your booking tool talks to your calendar, your online store talks to your payment processor, your help desk talks to your email. Each connection saves you time, and each one is also a door into your business that someone else built.
That matters more than most owners realize. In 2024, more than a third of all reported data breaches traced back to a weakness in an outside app or vendor rather than the business's own systems. The good news is that this risk is very manageable. You don't have to stop connecting apps, you just have to give a new one a quick, sensible check-up before you let it in. Here's the plain-English checklist we use with businesses across the Denver area.
Why connected apps are worth it anyway
Nobody builds every piece of their own software from scratch, and you shouldn't. Plugging in trusted outside tools lets you offer features that would take months to build yourself, at a fraction of the cost: payments, scheduling, chat support, analytics, you name it. The goal isn't to avoid these tools. It's to choose them well.
What can go wrong
When a connected app is a problem, it usually shows up in one of three ways:
Security
A seemingly harmless add-on can carry hidden malicious code, or simply have weak security of its own. Once it's connected, an attacker who compromises that app can use it as a path into your systems, to steal information or disrupt your operations.
Privacy and compliance
Even with a contract in place, a vendor can end up handling your customers' data in ways you didn't expect, storing it in another country, sharing it with their own partners, or using it beyond what you agreed to. That can quietly put you on the wrong side of privacy laws.
Operations and cost
If a connected app goes down or misbehaves, it can take part of your business with it: stalled orders, a dead checkout, a support queue that won't load. A weak connection can also be the thing an attacker exploits, with real financial consequences.
The checklist: what to ask before you connect an app
You won't be able to inspect a vendor's code yourself, and you don't need to. Most of what you need comes from asking the right questions and reading what they publish. Run through these before you flip the switch:
- Do they take security seriously, on paper? Look for recognized security certifications (names like SOC 2 or ISO 27001). They signal a vendor that gets its security checked by outsiders rather than just claiming it.
- Is your data encrypted? Ask how they protect information both while it's moving across the internet and while it's sitting on their servers. Encryption in both states should be the answer.
- How do people sign in? Modern, secure sign-in methods and the principle of "least privilege," giving each user and connection only the access it genuinely needs and nothing more, are what you want to see.
- Do they watch for trouble? A good vendor logs activity, alerts on suspicious behavior, and has a clear way to handle a security issue when one comes up.
- Do they give warning before they change things? Reliable providers tell you in advance when a feature is being retired, so a connection you depend on doesn't break overnight.
- What happens when they have an outage? Ask how they handle downtime and data recovery. You don't want to discover the answer during your busiest week.
- Where does your data live? Know which country it's stored and processed in, and check that it lines up with the rules you have to follow.
- What's in your contract? Good terms let you ask for documentation, review their security practices, and hold them to a timeline if something needs fixing.
- What are they built on? Apps are assembled from other building blocks. A careful vendor can tell you what they rely on and that they keep it patched and current.
Make vetting a habit, not a one-off
No tool is ever completely risk-free, but the right questions up front catch most of the trouble before it starts. Treat this as something you revisit, a quick reassessment of your key apps now and then, not a box you tick once and forget. This is the same mindset behind keeping an eye on apps your team signs up for on their own.
If you'd like a second set of eyes on the tools already plugged into your business, or on one you're about to add, that's exactly what we do. We'll review your connections in plain English and tell you which ones are solid and which ones we'd tighten up. Reach out and we'll take a look together.
