Read the story →“We had a great experience with NACIT setting up our network and systems. What really stands out is their availability and responsiveness. Whenever an issue comes up, they are there and ready to help.
They are knowledgeable, practical, and take the time to guide you toward the right solution instead of simply trying to sell you more. Their recommendations actually saved us a significant amount of money during the process.
It’s hard to find an IT company that you can truly rely on when you need them. I highly recommend NACIT for their knowledge, reliability, responsiveness, and excellent service.”
FAQ
Common questions
What does the free assessment include?
We meet with you, review your computers, network, security, backups and phones, and learn how your business works. Then you receive a detailed written quote. No obligation.
What are your service areas?
We’re based in Skokie, Illinois, and support businesses across the Chicago area, Northwest Indiana and Southern Wisconsin. Most issues are fixed remotely; we come on site when hands are needed.
How fast do you respond?
A person answers support calls live during business hours. Urgent issues get a technician within one hour.
Do you provide after-hours support?
Yes. Contract clients have a 24/7 emergency line for outages. Other requests are handled the next business day.
What industries do you serve?
Healthcare and dental, auto dealerships, telecom and construction, education, manufacturing, and restaurants and retail.
Can you work alongside our internal IT staff?
Yes. We can take monitoring, security and backups while your team handles daily requests — or back them up on projects.
Do you support Microsoft 365?
Yes: email, Teams, SharePoint, OneDrive, device management and security. We support Google Workspace too.
What cybersecurity tools do you use?
Business-grade tools for monitoring, device protection, email filtering and firewalls, run by our own engineers. We don’t publish product names — for the same reason you wouldn’t post your alarm code.
Do you offer compliance help?
Yes. We put HIPAA technical safeguards in place, document them, sign Business Associate Agreements, and help with cyber-insurance questionnaires. We work alongside your lawyer or auditor; we don’t replace them.
What happens during onboarding?
We document your systems, install our secure support agent, fix the most urgent risks, and give your team a simple way to reach us. Most onboardings take about one week.
Do you require contracts?
Agreements start at 12 months; multi-year agreements of up to 3 years are available. Everything is written down before we start.
Can you take over our phones and cameras too?
Yes. One partner for IT, phones and cameras means one number to call when something breaks.
