The Problem
Most IT Support Is Reactive, Not Protective
You call when something breaks. They fix it (eventually). Then you wait for the next fire. That's not IT management—that's break, fix with a monthly fee.
Break-Fix / Reactive IT
- Wait until something breaks, then call for help
- Hourly billing incentivizes long fixes, not prevention
- Security is an afterthought (or an upsell)
- No documentation—every problem starts from scratch
- Different tech every time—no one knows your systems
- Surprise invoices for "emergency" work
Proactive Managed IT
- 24/7 monitoring catches problems before users notice
- Flat monthly fee—our incentive is fewer problems
- Security included: MFA, endpoint protection, email defense
- Full documentation of your environment
- Dedicated team that knows your systems and business
- Predictable costs with no surprise bills
The Cost of Waiting
IT Problems Are Expensive, Preventable Ones Are Worse
Most businesses don't think about IT security or reliability until it's costing them money, customers, or reputation.
