The Fortress Linux operating system



The secure fundament of your computer
The Fortress Linux operating system is the foundation of our total security solution and is the product of 15 years experience in securing high-profile servers, desktops and embedded devices for international companies.

Fortress Linux is designed for 32-bit (x86) and 64-bit (x64) computers. Its kernel and the included software are fully customizable to your needs and can be automatically adjusted to your computer hardware during installation what results into a high performing, stable, compact and energy-efficient operating system.

By extensive research, 'thinking outside the box' and by only using the best and latest software available, we were able to create the complete security solution for anyone who wants to ensure the security, confidentiality, integrity and availability of their data and sensitive information on a computer, a network and the Internet by combining Fortress Linux with our other security products and services:
