It happened again.
Another CVSS 9 security flaw—this time in backup software.
I keep saying this: your tools are the way hackers are going to get in and take down your clients.
And yet, I was just in a session yesterday where the CEO of a major MSP software vendor (I’ll let you guess who) said something that made my stomach turn:
“The only way an MSP can survive in today’s competitive landscape is to buy all of their software from one vendor to get a huge discount.”
Let’s break that down.
The Fatal Flaw in the ‘One-Vendor’ Approach
This mindset sounds good in theory—one vendor, one bill, one stack, and a discount to sweeten the deal.
But here’s the problem: Hackers love predictability.
If you’re using one vendor for EDR, MDR, RMM, and backups, then the second they find a vulnerability in that ecosystem, you’re done.
They don’t have to break in multiple ways.
They don’t have to pivot across different security stacks.
They don’t have to figure out your defenses.
They already have the playbook.
Indiana Jones and the MSP Security Trap
Think back to Indiana Jones and the Temple of Doom.
What made that movie suspenseful? Indy had no idea where the booby traps were hidden. He had to adapt, dodge, and think on his feet to survive.
Now, imagine if the bad guys had handed him a detailed map of every single trap before he stepped inside.
Not very suspenseful, right?
That’s exactly what you’re doing for hackers when you consolidate your entire stack under one vendor.
One Breach. Total Takeover.
Here’s the reality:
- If one tool is compromised, every tool in the stack is compromised.
- If hackers breach the RMM, they have full control over your clients.
- If they hit your backup solution, they can delete or encrypt all your recovery data.
- If your security stack is predictable, they already know exactly how to bypass it.
One vulnerability in a monolithic security stack doesn’t just mean an incident.
It means total collapse.
Doing the Right Thing (Even When It’s Not Easy)
One of our core values is: Do the right thing.
Not the easy thing. Not the cheapest thing. The right thing.
And the right thing for your MSP is building a standards-based security program using best-in-class tools.
Not bundling everything under one vendor just to get a discount.
Because here’s the reality—it’s only a matter of time before that one vendor has its first zero-day.
When that day comes, do you want to be the MSP scrambling because your entire stack just got taken down?
Or do you want to be the MSP who built a resilient, layered, and unpredictable defense that keeps clients safe?
The choice is yours. But make it now—before the hackers do it for you.
