"Other DNS vendors were either too expensive or inappropriate. We wanted an appliance that was easy to use and that’s what we got with DNSBOX."
Paul Schuur, Senior Consultant, Qwise BV, Netherlands "DNSBOX is a good product and I have worked on it for a while"
Sirak Zewdie, LTE Network Engineer, NTIA / FirstNet Authority, USA "The DNSBOX is working well, it's reliable, and does not require much interaction from me"
David Breffitt, Senior IT Manager, Association of Corporate Counsel (ACC), District of Columbia, 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 responded within a day, and we shortly scheduled a meeting to discuss the need further"
Matthew Parris, GE Appliances, 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.
