We selected for our virtualized Exchange 2010 cluster deployment a year ago. Since then the virtual load balancers have been performing flawlessly. Support is always very speedy, and the sales staff has been very helpful as well. Overall we are very happy with our choice, and will gladly recommend them to other customers looking for a similar solution.

Kurt Travares - City of Tracy

Excellent product and service, worth every penny of the comparatively very low cost. We would never look anywhere else now.

Simple configuration aligned with excellent support assures us that no matter what changes are made to our LoB application, our appliance will continue to provide the performance and stability we require.

We have been using virtual appliances (VA MAX) since 2013 and not once have they let us down. Support has been excellent when I have had to use it for adding additional functionality or making feature requests which are always implemented quickly and without any problems. A highly recommended company that I cannot fault.

Mike Isaac - NHS

The installation and configuration of the virtual appliance is easy. The web interface is cleanly designed and reacts quickly. If a real server fails, the failover works seamlessly. In other words: top solution with good and fast support.
