Joomla: sovereignty score and 8 European alternatives

Joomla is a free, open-source content management system released under the GNU General Public License. The official site describes two ways to start: installing Joomla on your own server, or launching a website through a hosted alternative. Joomla is used to build and manage websites.

Joomla is maintained by Open Source Matters, Inc., a corporation incorporated in New York, USA, which operates the official websites and holds the copyright. The software is distributed as source code that organisations can install themselves, so the data location is set by the server or hosting provider chosen. For a European organisation, the main point is that the maintainer is a US organisation, which matters for governance and jurisdiction, while the hosting choice determines where personal data is stored.

Why digital sovereignty matters with Joomla

Joomla 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.

Joomla 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.

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