Proton OS is a desktop-oriented Linux distribution based on Debian's "Stable" branch. Featuring the KDE Plasma desktop, it is built with small businesses in mind, designed primarily for office workstations, shared computers and reception systems. It also includes the Calamares system installer and is pre-configured to automatically install all security updates. The project's goal is to give businesses greater control over their computers while reducing dependence on proprietary operating systems and unnecessary data collection.
