We create secure, zero-knowledge apps that empower people to take control of their data. Our end-to-end encryption protects information in the cloud from everyone, even from us.
We’re committed to protecting our users’ privacy. We believe that the right to privacy is fundamental in the digital world, both for individuals and businesses.
We believe that secure tools should seamlessly fit into workflows. Our goal is to keep it as simple as possible, so that people don’t need to learn new ways of doing things to stay secure.
Our story started when Istvan Lam, only 12, received his first cryptography book as a gift from his family. It sparked his interest in cybersecurity and led him to start his fight for digital privacy in his late teens and research cryptography further. Ten years after in 2011, he founded Tresorit with two other students and the head of a leading IT security institution. Since then, Tresorit has grown into a company bringing secure collaboration to teams all over the world.
