SolydXK: sovereignty score and 8 European alternatives

SolydXK is a Linux distribution based on Debian Stable. It is offered in editions with the lighter Xfce desktop and with KDE Plasma, which places particular emphasis on configurability. The distribution is distributed as an ISO image, and its live system allows users to try the operating system before installing it. SolydXK began in 2013 as a Debian-based version derived from Linux Mint and has since been developed by a community of users and developers.

SolydXK is a Dutch distribution, developed in the Netherlands. The website, however, names no legal entity and shows no imprint, and no commercial owner is stated. The distribution is free software under open-source licences, and its Debian base makes it possible to review, rebuild and maintain the system on your own infrastructure. It also includes some proprietary software, so organisations should check the licences of the packages they install. The website does not describe a cloud service in which customer data is stored.

Why digital sovereignty matters with SolydXK

SolydXK is headquartered in NL and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so SolydXK scores best on data residency.

SolydXK is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs SolydXK together with your other vendors and gives a total score, a heatmap and the main risk drivers.
