"The daily revenue cost of our system going down could be very high and we realised that the cost of a new and outsourced DNS solution made sense."
Mark Albutt, Technical Manager, Probrand Limited, UK "We have been using DNSBOX for 3 years now and it has been absolutely fantastic! The best thing about it is the reliability"
Moataz Sabri, Topnet Internet Services, Saudi Arabia "With ApplianSys there's a guaranteed level of service - we know you are experts at what you do."
Joe Meno Network Operations Mgr, Pacific Data Systems, Guam, USA "I would recommend ApplianSys, as they are customer-oriented"
Matthew Cornett, Tech director/Tech contact, Galax City School District, 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.
