Comparison of Communication Tools for Companies
In contrast to chat apps for private users, business solutions offer a console where company administrators can manage the employees. Thanks to Threema Work’s high flexibility, the service easily adapts to every organization’s needs. In BYOD scenarios, Threema Work scores extra points with Threema MDM, while most other solutions only support external MDM systems. Threema Work combines comprehensive pre-configuration options with a straightforward app distribution.
All solutions support integration into directory services. External users can join Threema Work without having to complete a tedious registration process and even without providing a phone number or email address. On top of that, Threema Work can also be restricted to a closed user group.
Not to offer an option to archive user chats on a central server (e.g., for compliance purposes) is a deliberate decision of Threema Work because this would, in theory, allow the service provider to access message contents, which, in turn, would render the security benefits of end-to-end encryption completely useless.
