"DNSBOX was easy to deploy. The ApplianSys support engineers guiding us understood our technical requirements well - we were assured that we were in good hands." Nokia Siemens Networks "I fully endorse ApplianSys claims about 'Fixing The Connectivity Problem'. Their experience of delivering large scale rollouts is invaluable." Maldives Ministry of Education "DNSBOX is very reliable vs cloud based DNS solutions and other DNS servers. There has been a noticeable difference in the reliability since we moved to DNSBOX" Luke Chutckhan, Clever ICT, UK "I love a product that just does what it's supposed to with minimum fuss. DNSBOX just works for the purposes we need - redundant reliable DHCP service." Kevin Williams, Whittier Regional Vocational Technical High School "With CACHEBOX our 200Mbps connection runs beautifully, but I know of other districts that have a 1Gb connection and slow internet. CACHEBOX has been my favourite purchase for the school in the last decade!" Newcomerstown School District, USA "I've worked with a lot of DHCP appliances, DNSBOX is by far the easiest I've ever dealt with. It's exactly what you hope for when you buy a box like this - it just works." Phoenix Suns, USA "CACHEBOX is the best investement I have made to help with the district's network speed" Joey Andrews Technology Coordinator, Arkadelphia School District, USA "Your support is amazing even though you are on the other side of the world! I use ApplianSys as an example of what to do and what not to do when engaging with support!" Felixton College, South Africa "DNSBOX was easy to deploy.
