Rock solid appliance

DNSBOX400 is a hardened Linux based appliance optimized for performance, robustness, security and ease of management.

The custom Linux OS has been developed by ApplianSys specifically for creating secure appliances. Our approach, refined over several years and employed across our appliance range, has been to build from the ground up, supporting the core application with only the most critical network tools.

A key aspect is use of solid-state storage, with no hard drives in these appliances. Hard drives account for 90% of hardware failures, so DNSBOX400 is 10x more reliable than alternatives. It is also more robust in situations where there is a power loss, with no loss of data or settings and immediate reboot.
