About
Threema Work is a professional communication solution for organizations, including SMEs, large enterprises, and associations, that need to handle confidential communication efficiently while meeting strict data protection compliance requirements. It offers centralized user management and access control (MDM), enforcement of corporate policies, API-based integration with existing systems, and easy employee onboarding even without company-owned devices. The app is available as both a mobile and a desktop app.
For daily collaboration, Threema Work includes text and voice messages, group chats, secure voice and video calls, file sharing, polls, message editing and deletion, emoji reactions, and administrator management of groups, broadcasts, and contacts. Confidential chats can be additionally protected with a PIN or fingerprint. Security features include end-to-end encryption, Perfect Forward Secrecy, and a zero-knowledge architecture, so message content is visible only to the sender and recipient. The service runs on Threema's own servers in Switzerland under Swiss data protection laws, and an optional on-premises deployment is available for maximum data sovereignty.
The website also lists upcoming modules, including SecureShare for self-hosted large-file sharing, Conferencing for encrypted meetings that external participants can join via a browser link, EasyConnect for secure communication with external contacts, TrustCircles for controlling contact visibility, and AiBridge for connecting approved AI providers within the messenger. These are marked as coming soon or as upcoming features.
