"The reduced deployment costs and Total Cost of Ownership allowed us to deploy more units making name resolution a local service."
Chief Network Architect, Leading Hollywood Studio, USA "I commend you for building a wonderful device, it’s exactly what you hope for when you buy a box like this"
Anthony Grande, Senior Systems / IT Network Administrator, Phoenix Suns, USA "ApplianSys has made managing our DNS amazingly simple. Once the boxes were up and running, it was a case of ‘set it and forget it’..."
Matt Niswonger, Techician at UltraTech Resources, USA "I’ve worked with a lot of DHCP appliances, DNSBOX is by far the easiest I’ve ever dealt with"
Anthony Grande, Senior Systems / IT Network Administrator, Phoenix Suns, USA "We have used DNSBOX for a long time, managing the DNS server is much easier than before!"

Hardened Operating System for Security and Reliability

DNSBOX-hardwareDNSBOX’s security hardened Linux based operating system (OS) is a custom-built appliance ‘distribution’, developed by ApplianSys to maximise security and reliability. The OS has been stripped clean and locked down:

  • Programs, services and files found on a standard Linux distribution that are not required for a DDI appliance are removed. This makes DNSBOX more secure and boot significantly faster than a standard Linux server.
  • The appliance is protected by a fully configurable on-box firewall: ports are only opened in the firewall as needed when services are enabled. All other traffic is dropped.
  • DNSBOX uses a read-only compressed file-system. This is best practice for appliances, being extremely solid and reliable. The fact that core operating system files are maintained read-only adds an extra security layer and avoids accidental damage from user errors.

The OS has a small footprint: once booted, it is retained in RAM, making it very fast.
