Our vision
Control over digital values
Our vision is to empower all in getting back control over their digital valuables, regardless of the workflow they choose to follow. We believe that security doesn’t have to be complicated – it needs to be a seamless part of your work routine.
Privacy by design
Our goal is to keep Tresorit as simple as possible, so that people can stay secure without having to take extra steps to protect their data.
Our story
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 Szilveszter Szebeni and Gyorgy Szilagyi - both fellow students at EPFL, one of Europes most prestigious tech universities based in Lausanne. Since then, Tresorit has grown into a company bringing secure collaboration to teams all over the world.
