Common Questions

Frequently Asked Questions

Have a question that isn't listed? Get in touch. We're happy to help.

01 What is ransomware and how can I protect my business?
Ransomware is malicious software that encrypts your files and demands payment to unlock them. Protection requires layered defences: up-to-date patching, endpoint security, email filtering and staff training. Most importantly, you need reliable offsite backups so you can recover without paying the ransom. We implement all of these as part of our managed cybersecurity service.
02 What is the difference between managed IT and break-fix support?
Break-fix means you call someone when something breaks and pay an hourly rate to fix it. Managed IT is a proactive, flat-rate monthly service. We monitor your systems 24/7, apply patches and resolve issues before they affect your business. Most clients prefer our managed IT services because it helps avoid expensive downtime and lets them stick to a predictable monthly IT budget.
03 Do you support residential customers?
Yes. We offer residential IT support both in your home and at our office. Whether you need a home network set up, a laptop screen replacement, a virus removed or a new computer configured, we can help.
04 Do you have experience in my industry?
We serve businesses across a wide range of industries in Eastern Ontario including accounting, law, dental, construction, retail and non-profits. Each industry has unique compliance and workflow requirements. We bring our decades of expertise to every client we work with. We specialize in supporting industries and software of all types.
05 Can you help us move our IT to a new office?
Absolutely. Office moves are one of our most common project engagements. We handle network infrastructure planning, server relocation, workstation setup and phone system cutover so your move goes smoothly and downtime stays minimal.
