Samba: sovereignty score and 8 European alternatives

Samba is a free implementation of the SMB and Active Directory protocols for Linux and other UNIX-like systems. It provides file and print services to Windows and other SMB clients, and can act as an Active Directory domain controller or as a member server. Organisations use Samba to integrate Linux and UNIX servers and desktops into Active Directory environments, or as a file server on top of cluster filesystems. It is installed as server software on your own systems.

Samba is developed and maintained by a worldwide community of individuals and companies, the Samba Team; the project is a member of the US non-profit Software Freedom Conservancy and receives support from, among others, the Sovereign Tech Fund. The software is licensed under the GNU General Public License. The samba.org site lists commercial support providers, globally and by country. Because you host Samba yourself, files and user data stay on your own infrastructure.

Why digital sovereignty matters with Samba

Samba is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Samba hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Samba 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 Samba together with your other vendors and gives a total score, a heatmap and the main risk drivers.
