TI-Messenger (TI-M) is the official standard for secure communications across the German healthcare system. Built on the open Matrix standard, TI-M ensures digital sovereignty, interoperability and end-to-end encryption for the entire sector.
TI-M is mandated by Gematik, the National Agency for Digital Medicine that is majority-owned by Germany’s
Federal Ministry of Health
. It’s a world-leading initiative connecting over 150,000 healthcare organisations and 74 million patients within a private, federated network. By combining secure professional identity verification with a unified medical directory, TI-M provides a trusted and seamless foundation for the future of digital medicine.

TI-Messenger operates as a private Matrix-based federated network, restricted exclusively to Gematik-approved organisations. To maintain this closed ecosystem, all connections are managed by a TI-Messenger Proxy. This secure border gateway enforces strict communication rules and ensures total compliance with Gematik specifications. Element’s Secure Border Gateway is the foundational building block for this proxy, serving as a core, integrated component of our ESS TI-M solution.
Benefits from modern memory safety and concurrency models, eliminating data races and reducing operational risk.
With an idle memory footprint of just 10 MB compared to 800 MB in the TI-M reference implementation.
