What makes BundesMessenger special

Unlike commercial apps, we developed BundesMessenger specifically to meet the requirements of the Bundeswehr.

It is more than a chat tool. It is an expression of digital sovereignty. BundesMessenger is fully subject to German data protection standards, is used by the Bundeswehr and is developed transparently. Unlike commercial services and providers, no data is sold and no advertising is displayed. The platform is based on open standards, is open source and can be operated federally – from local municipality to federal level.

Data stays where it belongs – protected from unauthorized access and unintended leakage.

And because everything is open source, BundesMessenger can be individually adapted to the needs of public administration and integrated into your own system landscape. We take care of maintaining and further developing the product behind the app and provide monthly updates. That is secure, free and self-determined messaging for public organizations in Germany.

Secure communication – more important than ever

In an increasingly digital world, secure communication is becoming a critical factor. For the public sector in particular, the security, reliability and sovereignty of digital communication solutions are what count. That is exactly why we developed BundesMessenger: as a secure alternative to commercial apps for administration, public authorities and organizations with a public mandate.
Sensitive data
Public authorities process sensitive data that requires the highest level of protection against unauthorized access.
Geopolitical change
Dependencies on foreign tech corporations pose strategic risks to national security.
Compliance requirements
Strict data protection laws and information security policies require demonstrably secure solutions.
Increasing cyberattacks
Government infrastructures are increasingly the target of cyberattacks. They require special protection.

The reality today

Public authorities often use proprietary, commercial messengers or depend on digital technologies and services from countries outside the EU. This endangers both data security and their own digital sovereignty.
