Threema Work

Threema Work is a business messenger from Switzerland, made for companies, public authorities and other organisations that need confidential communication inside and outside the organisation. Its feature set covers encrypted chat and voice notes, groups, video calling and sharing of files. Administrators manage users and licences from a web-based management cockpit. Clients exist for iOS and Android as well as for Windows, macOS and Linux desktops. Organisations with special demands can also get Threema OnPrem, a separate variant that runs on their own infrastructure. Switzerland is not in the EU.
