Highly Secure Communication for Businesses

Data protection, productivity, and compliance – without compromising usability.

A Strong Foundation for Your Communication

All our Threema solutions are unique in their implementation, yet they are built on the same strong foundation. The three aspects of trust, transparency, and technology form the core of our philosophy and provide the basis for secure, reliable, and future-proof communication solutions.

Trust

Secure communication starts with trust. Threema protects your content through consistent end-to-end encryption – without requiring any personal information such as a phone number or email address. The principle of data minimization is at the core of our approach. Millions of users worldwide, both private individuals and businesses, rely on this security every day.

Transparency

If you promise security, you have to prove it. Threema is open source, undergoes regular independent audits, and fully complies with all GDPR requirements. Instead of tracking or hidden data usage in our applications, we rely on consistent data minimization and clear processes, ensuring full transparency.

Technology

Modern, powerful, and versatile: Threema relies on future-proof technology to enable stable, cross-platform communication – whether for private use, within organizations, or fully self-hosted. With Active Directory and MDM integration, APIs, and a flexible infrastructure, Threema seamlessly adapts to any environment. Secure communication made in Switzerland.
