About this app

Professional Team Communication and Collaboration

Threema Work. For Companies functions as a dedicated messaging solution tailored for organizations and teams requiring dependable internal connectivity. The platform employs end-to-end encryption to protect the confidentiality of text and voice messages, media, and documents exchanged between colleagues. Teams can organize group chats, conduct voice and video calls, share various file formats including PDF, MP3, ZIP, and GIF, or distribute polls and distribution lists to streamline coordination.

Administrative Controls and Privacy Protection

Administrators are equipped to manage users, pre-configure application parameters, and define organizational usage policies. To support data governance, users can mark specific messages as compliant or non-compliant. Privacy measures are further reinforced through options such as password, PIN, or fingerprint protection for confidential chats, working-hour restriction policies for notifications, and contact identity verification via QR codes. Messages can also be edited or deleted for chat partners after sending.

Getting Started and Setup Workflow

New users open the application to generate a Threema ID, choosing whether to associate optional contact details or maintain an independent account structure. Contacts can be added directly via their Threema ID or by scanning a QR code to verify identity before initiating secure private conversations. Team members can then exchange text, voice notes, pictures, videos, and locations, or initiate live voice, video, and group calls when verbal discussion is more efficient than typing.
