AlmaLinux OS vs. FortiOS

AlmaLinux OS is an enterprise Linux operating system used across the globe by enterprises, supercomputers, and hobbyists alike, but it’s guided and built by the community. We were the first downstream RHEL clone to be released after the announcement by Red Hat that support for CentOS Linux was ending, and we shifted to maintaining RHEL compatibility in the wake of Red Hat’s announcement in June that they would no longer be releasing their SRPMs. Our goal is to provide a stable, long-term option for folks who have historically used CentOS Linux, and for whom CentOS Stream is not an option.

FortiOS is Fortinet's proprietary operating system that serves as the foundation of the Fortinet Security Fabric, delivering integrated security and networking capabilities across various environments, including on-premises, cloud, hybrid, and converging IT/OT/IoT infrastructures. By enabling the convergence of security and networking, FortiOS helps close security gaps and simplifies management, ensuring consistent user experiences and unified security policies.
