"DNSBOX really does exactly what we were looking for"
Jim Frackoviak, District IT Manager, Summit School District, USA "I was trying to get away from Windows, I prefer having a dedicated appliance (DNSBOX)"
Bill Wyatt, Georgia State Treasury, USA "DNSBOX is a user friendly and powerful tool to explore and is also very cost effective"
Saifullah Tajuddin, DST Multimedia Sdn Bhd now UNN, Brunei "Making host files is now much simpler, quicker, and less error prone."
Mike Neverdusky, CDE Lightband, USA "After switching to DNSBOX appliances, we've found fewer cases of human error and better tracking of changes..."
Teddie Strother, Senior Systems Administrator, University of Michigan-Dearborn, USA

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.
