What Our Customers Say...

We Took the Leap to Have Our Systems Monitored Consistently

CSU was instrumental in defining deficiencies within our computer equipment and network. They provided us with recommendations and a proposal to watch our Server 24x7, something we had never done before. Now if our Server has problems, CSU knows about it immediately and is able to remedy the problems, most times remotely. In addition, our operating system is kept up to date, as well as our virus protection. All of this is done without it affecting our daily use of our systems. We have been very pleased we took the leap to have our systems monitored consistently and we are very pleased with the staff’s technical abilities and customer service.

Their Skilled Team Works Hard To Ensure Our Full Functionality

The ABRA gives us the ability to function in an electronic medical record environment with the confidence that we have constant redundant backup.  We have already relied on this fallback server one time when we had to have a raid hard drive replaced on our main server.  The technology allowed us to continue providing patient care with minimal interruption.  The best outcome of using CSU’s ABRA service is having access to their skilled team for other IT issues that may arise in our practice.  In the example above, Chuck Sherman helped repair the hardware issue that we had on our main server so that we could get back to full functionality.

They work remotely and are ready at a moment’s notice

We are a large staffing agency, providing nurses for INOVA Fairfax Hospital. Our staff is available to the hospital 24/7 and we have to be able to provide nurses at a moment’s notice. We are very fortunate to have found Computer Services Unlimited. They were able to stabilize our systems when they took over our network. They established a work from home policy for our company and trained our staff on how to log in remotely. If any of our staff has a problem, they call CSU directly and are taken care of immediately.
