New versions DOMOS 6 & Qiata 4.11 available


New foundation, old strengths

our brand new versions are now available!

It has been 20 years since the release of DOMOS 1 in 2003. Back then, SECUDOS' own operating system was based on Red Hat Enterprise Linux (RHEL) and offered customers, then as now, a customer-oriented and hardened operating system with its own WebUI. In the past years we have acquired a lot of knowledge and perfected our DOMOS more and more. TODAY we release DOMOS 6, the latest version with a proven look & feel, but a new "engine".

With DOMOS 6, Qiata gets the latest version of our in-house operating system. DOMOS 6, unlike its predecessors, is no longer based on CentOS, but on AlmaLinux. AlmaLinux is a binary compatible 1:1 clone of RHEL® and CentOS (pre-stream).

DOMOS 6 is an enterprise-class operating system and a stable Linux distribution that comes with a long support window. DOMOS is characterized by its focus on sustainable stability, providing a robust platform for all business areas. Our DOMOS 6 operating system stands for efficiency, independence and security. The self-sufficient OS is a deliberately hardened system that meets the high security demands of complex network structures.
