EU tests Matrix protocol as sovereign alternative for internal communication
Brussels examines Matrix as a scalable alternative after Signal proved too limited for the Commission’s communication needs.
The European Commission is testing a European open source system for its internal communications as worries grow in Brussels over deep dependence on US software.
A spokesperson said the administration is preparing a solution built on the Matrix protocol instead of relying solely on Microsoft Teams.
Matrix is already used by several European institutions, including the French government, German healthcare bodies and armed forces across the continent.
The Commission aims to deploy it as a complement and backup to Teams rather than a full replacement. Officials noted that Signal currently fills that role but lacks the flexibility needed for an organisation of the Commission’s size.
The initiative forms part of a wider push for digital sovereignty within the EU. A Matrix-based tool could eventually link the Commission with other Union bodies that currently lack a unified secure communication platform.
Officials said there is already an operational connection with the European Parliament.
The trial reflects growing sensitivity about Europe’s strategic dependence on non-European digital services.
By developing home-grown communication infrastructure instead of leaning on a single foreign supplier, the Commission hopes to build a more resilient and sovereign technological foundation.
