About Tresorit

Tresorit, established in 2011, operates in the cloud storage and collaboration market with a sharp focus on security. The company was founded by Istvan Lam, Szilveszter Szebeni, and Gyorgy Szilagyi, who leveraged their backgrounds in cryptography and data security to address vulnerabilities they perceived in mainstream cloud services. Lam, who serves as the CEO, previously engaged in cryptography research at the Budapest University of Technology and Economics, which formed the intellectual bedrock of the company.

The firm provides a suite of end-to-end encrypted productivity tools designed for businesses to manage, store, and transfer sensitive files. Tresorit's business model is primarily subscription-based, offering various tiers of service to a client base that spans over 10,000 businesses globally. These clients range from small teams to large enterprises in sectors like legal, healthcare, and finance, where data confidentiality is paramount. Revenue is generated through recurring fees for its secure collaboration platform. A significant milestone in the company's trajectory was its acquisition by Swiss Post in 2021, a move that allowed Tresorit to expand its market presence while retaining its brand and operational autonomy.

The core of Tresorit's offering is its 'zero-knowledge' end-to-end encryption, which ensures that only the user and those they authorize can access the content of their files; not even Tresorit's own administrators can view the data. This is a key differentiator from many competitors. The platform includes features such as secure file sharing with granular access controls, password-protected links, and detailed activity logs for administrators. Its e-signature solution, Tresorit eSign, allows for the legally binding signing of documents within the same secure environment. The service is designed to integrate into existing workflows, aiming to provide a high level of security without compromising user productivity.
