Meet Threema

Threema is a messaging app for text, files, and voice or video calls with end-to-end encryption. Personal accounts can work without a phone number or email address. The app provides private conversations and group communication within a service developed in Switzerland.

Threema Work adds a managed workplace messenger, with a central console for user permissions and app settings. Teams can use group conversations and calls while an organization controls the configuration. Threema OnPrem offers a self-hosted deployment on the organization's infrastructure. The product family gives individuals and businesses different ways to use the messenger according to how they want to operate and manage it.
