"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 "Now we can offer much greater capacity with our DNS setup and we no longer have to worry about six year old PCs breaking down."
Jonathan Walsh, IT Manager, Boral, Australia "Stable, redundant, out of sight, out of mind DHCP at its finest"
Kevin Williams, Director, Whittier Regional Vocational Technical High School, USA "DNSBOX is much easier to manage than Windows!"
Bill Wyatt, Georgia State Treasury, USA "I was trying to get away from Windows, I prefer having a dedicated appliance (DNSBOX)"

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.

Because DNSBOX is versatile and scalable, our customers around the world come in all shapes and sizes. Some want to simplify, control and protect their DDI services, others just want to solve a specific DNS or DHCP headache.
