Threema

Threema provides end-to-end encrypted exchange of messages, calls, and files, designed for maximum confidentiality and data sovereignty.

The platform is available in two main versions:

• Threema Work for organizations, featuring centralized user management and compliance tools

• Threema Private for individuals, which allows anonymous use without requiring a phone number or email address.

Threema is trusted by over 8,000 organizations and 12 million users worldwide, including security-critical sectors such as military, government, and healthcare.

The solution supports structured group chats, encrypted voice and video calls, and can be self-hosted (Threema OnPrem) for full control over data.

Threema is developed in Switzerland and is fully compliant with GDPR, making it a leading choice for secure communication in an era of increasing cyber threats and data privacy concerns.
