"I love the DNSBOX solution. It's working really well for us – much more stable and reliable than our previous virtual solution"
James Montoya, USGS (US Geological Survey) - Colorado, USA "ApplianSys offers a very helpful service. DNSBOX seems to fit the bill regarding functions"
Matthew Parris, GE Appliances, USA "We needed to take DNS management in-house in a hurry. Without DNSBOX, we'd have been looking at several weeks"

Evan Tiberi, Network Manager, Aptakisic-Tripp Community Consolidated School District 102, USA "DNSBOX is easy to manage, handle and is very stable. It is the best DNS product ever!"

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.
