Highly secure communication for businesses. Data protection, productivity, and compliance – without compromising usability.
Communication at the highest security level. The self-hosted communication solution for highest demands on security and confidentiality.
Privacy without compromise. Communicate with friends and family in complete confidentiality – no data snooping, no metadata collection, no compromises.
Since 2012, we have been developing the Threema app in Switzerland, giving individuals, companies, and public authorities control over their data and ensuring uncompromising privacy protection.
“Privacy by Design” means that we view data protection not just as a legal requirement, but as a guiding principle for our products and services.
Threema protects confidential information, avoids metadata, and is GDPR-compliant – “Security by Design” is our philosophy.
