"DNSBOX is very, VERY reliable!"
Colin Norford, Cache Administrator/IT Manager, The Cable, Saint Kitts and Nevis "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 "DNSBOX is one of the most reliable elements in our enterprise. Simple to install and configure, it has required zero maintenance"
CTO, Texas Association of Local Health Officials, USA "I haven't had a single issue with DNSBOX. I especially appreciate the security features provided by the role separation of Master and Slave units."
Jojo Dela Plana, SURE South Atlantic Ltd, Maldives "ApplianSys Support has been very helpful in getting us set up"

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.
