Open 2.0: sovereignty score and 8 European alternatives

Open 2.0 is an open-source platform for building collaborative portals and intranets, mainly for public administrations. Its modules cover a content management system, news, events, blogs, newsletters, surveys, file sharing, community groups, discussions, video calls and a ticketing system, with role-based user management and workflows. It is installed as a PHP web application with a MySQL database and supports sign-in through the Italian identity systems SPID and CIE.

Open 2.0 is promoted by Regione Lombardia, the regional government of Lombardy in Italy, and published on GitHub under the GPL-3.0 licence. The project site names Regione Lombardia as copyright holder, and the project metadata classifies maintenance as community-based. The platform is listed in the Developers Italia catalogue. Because you install the software yourself, data can stay on infrastructure you control; the project site describes a typical installation on containers at AWS, a US provider, in a European region, where the US CLOUD Act may then be relevant.

Why digital sovereignty matters with Open 2.0

Open 2.0 is headquartered in IT 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 Open 2.0 scores best on data residency.

Open 2.0 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 Open 2.0 together with your other vendors and gives a total score, a heatmap and the main risk drivers.
