"The DNSBOXes meet all of our expectations. It is very rare when a product actually performs as stated in the marketing literature..."
Randy Haynes, Senior Network Engineer, EDS, USA "DNSBOX can be managed by non-professional technicians. Just teach them a few quick steps then off they go"
Naif Orabi, Network Administrator at TAIF Ministry Of Education, Saudi Arabia "We have had very good experiences with Appliansys Support since the beginning"
Thierry Prudat, Senior Network Engineer, NorthC Schweiz AG, Switzerland "The OBI team had never used a solution like DNSBOX before - helpful in increasing stability and manageability of our environment."
John Marcellus, Director of IT Operations, Oklahoma Blood Institute (OBI), USA "The DNSBOXes basically sit there and do their job as expected, we have very little interaction with them"
Andy Brennan, Technical Operations Team Leader, The Guinness Partnership, UK

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.
