How we’re building Tresorit
We encrypt everything to know nothing.
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 value privacy as a human right.
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 put people at the center.
We believe that secure tools should seamlessly fit into workflows. Our goal is to keep Tresorit as simple as possible, so that people can stay secure without having to learn new ways of doing things.
Our story started when Istvan Lam, at the age of 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 later in 2011, he founded Tresorit with two other university 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.

Zero-knowledge means we can never read our users' files. End-to-end encryption guarantees that any information, personal data, intellectual property, or confidential business files stay private and secure.

- Tresorit is established by Istvan Lam, Szilveszter Szebeni and Gyorgy Szilagyi
Istvan Lam, Szilveszter Szebeni and Gyorgy Szilagyi started Tresorit while still at university. They didn't trust mainstream file sync apps and decided to create a service with end-to-end encryption at its heart.
