What Our Customers Are Saying


I cannot afford to have down time

I have been working with Computer Services Unlimited (CSU) since 1993. Chuck and his team have been very helpful in providing support for our network related issues. They take care of our server, workstations, and printers. I am a busy real estate agent and time is money.  I cannot afford to have any down time.  CSU handles any problems that arise.  They take the time to listen to my concerns and then advise me on the best solutions for our company.

They have given us foundational knowledge in the basics of cyber-security…

I knew our practice needed better Cyber Security measures, but we didn’t know where to start...

Fortunately for us, CSU’s Cyber Security Audit was exactly what we were hoping it would be. They have been instrumental in making sure that our practice is protected from today’s growing cyberthreats.

They have given us foundational knowledge in the basics of cyber-security, such as common methods of hacking, why small practices are being targeted by criminals, what a cyberattack could mean for our practice and how to prevent hackers from getting into our network.
