"The intricate nature of our system made it too challenging to support. With DNSBOX this is no longer the case."

Chief Network Architect, Leading Hollywood Studio, USA "From opening the box to a fully functional unit was 10 minutes."
Chief Network Architect, Leading Hollywood Studio, USA "The DNSBOXes meet all of our expectations. It is very rare when a product actually performs as stated in the marketing literature..."

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.
