I was able to find an affordable solution for our small business needs that fit within my budget constraints! The product is very easy use with no training needed at all once you open it up (which can be confusing if your not familiar) It allows me control every aspect from email filtering through antivirus protection right down loading files into memory cards etc.. As long ago they stopped supporting older versions which we were depending upon but there are other options out their now so just make sure when signing any new contract or renewal agreement what version will still work in 2 years time without having upgrade fees added onto them!!
