Threema Work

Threema Work provides end‑to‑end encrypted instant messaging for businesses, aiming to keep corporate communications confidential while meeting data‑protection and compliance requirements. It runs on its own servers in Switzerland, is by Swiss data‑protection law and an ISO 27001‑certified data centre, and uses perfect forward secrecy and a zero‑knowledge architecture so that only intended recipients can read messages.

The platform is designed for organizations of any size, from small enterprises to large corporations and associations. It offers centralized user management, mobile‑device‑management (MDM) integration, and APIs for connecting to existing systems, helping enforce corporate policies and prevent shadow‑IT usage. Employees can be onboarded quickly, even on personal devices, and the solution protects against unauthorized access if a device is lost or staff turnover occurs.

Threema Work is positioned as a privacy‑first alternative to mainstream messaging apps, emphasizing secure one‑to‑many communication, scalability, and flexibility for modern team collaboration while remaining compliant with strict data‑security standards.
