The Mobility Data Space (MDS) is a decentralized data space funded by the German Federal Ministry for Digital and Transport (BMDV). Digital sovereignty is not a buzzword, but a core design principle—particularly for data infrastructure, governance, and collaboration.

While the MDS is already sovereign at the infrastructure level, it previously lacked a suitable solution for internal and external communication. Existing tools met either functional requirements or security standards, but not both—and not in alignment with European values.

The MDS’s objective was clear: communication should be as sovereign, secure, and European as the data space itself, forming an organizational and technical bridge between data infrastructure, governance, and everyday collaboration.

During the evaluation of different solutions, Wire stood out through a clear combination of sovereignty, security, and everyday usability:

• End-to-end encrypted communication with a high level of integrity
• Hosting and development entirely based in Europe
• Proven use in the public sector, including the German Bundestag
• Full feature set: one-to-one and group chats, audio and video calls, screen sharing

In direct comparison, sovereignty and functional breadth were the decisive factors in choosing Wire.

The implementation of Wire within the Mobility Data Space was straightforward:

• Quick setup, immediately usable across multiple devices
• Seamless integration into existing workflows and teams
• Guided onboarding by the Wire team, supported by clear resources and hands-on assistance

This approach allowed technical and organizational challenges to be addressed at an early stage.

With Wire, communication within the MDS has changed noticeably:

• Faster coordination across hierarchical levels
• Secure, sovereign communication aligned with European values
• More productive collaboration through targeted features such as ping messages for urgent matters
• Secure inclusion of external stakeholders in conversations—an essential advantage for a connected ecosystem

Wire therefore meets the MDS’s original objective: a sovereign messenger that delivers strong functionality and fits seamlessly into the organization.

With the adoption of Wire, the Mobility Data Space sends a clear signal: digital sovereignty in Europe is achievable today.

For the MDS, Wire represents another building block on the path toward a sovereign organization, complementing the data space with a secure, European communication layer.
