DOMOS by SECUDOS – an operating system built for security


DOMOS is the hardened operating system from SECUDOS. It was designed from the ground up to include only what is truly necessary – nothing more, nothing less. This reduction minimizes the attack surface and increases stability. At the same time, DOMOS comes with integrated backup functions and, together with SDR, can be restored in no time if needed. The result is a platform that runs reliably, is simple to operate, and provides the failover resilience required in critical environments.
