Luxchat4Gov, developed by Luxembourg's Ministry of Digitalisation together with Lu-CIX, is a secure messaging platform tailored for the public sector, emphasizing digital sovereignty and interoperability. Built on the open-source Matrix protocol, Luxchat4Gov ensures encrypted, end-to-end communications hosted within national data centers, guaranteeing that all data remains under Luxembourgish jurisdiction. This approach not only enhances security but also provides full control over governmental communications.

This presentation will highlight how Luxchat4Gov leverages the Matrix protocol to ensure seamless interoperability between systems, while maintaining stringent data security. By adopting this platform, Luxembourg sets a precedent for achieving digital autonomy while fostering an interconnected and secure communication environment across government entities, and the national Luxchat ecosystem.
