History

edit
Logo as of 2016

Tresorit was founded in 2011 by Hungarian software developers Istvan Lam, Szilveszter Szebeni and Gyorgy Szilagyi with the aim of providing a secure alternative to traditional cloud storage solutions. The company developed a cloud collaboration platform based on client-side end-to-end encryption and a zero-knowledge architecture. [5]

In its early years, Tresorit gained attention through a public security challenge inviting researchers to attempt to compromise its encryption system. The initiative received coverage in technology and cybersecurity media.[6]

The company initially positioned itself as a secure alternative to conventional cloud storage services and gradually expanded its offering toward enterprise-focused collaboration tools.

In 2021, Swiss Post Communications Services acquired a majority stake in Tresorit. [7] The company is now part of Swiss Post, and continues to operate independently within Swiss Post’s digital division, while benefiting from the broader infrastructure and institutional framework of its parent organization.

Tresorit has offices in Zurich, Munich, and Budapest.

Products and Services

edit

Tresorit provides a cloud-based platform for secure file storage and collaboration. Its services include encrypted file sharing, email encryption, electronic signatures, and encrypted data rooms for managing sensitive documents and workflows.

The platform is available on Windows, macOS, Linux, Android, and iOS.

Technology

edit

Tresorit uses client-side end-to-end encryption based on a zero-knowledge model. Files are encrypted on the user’s device before being uploaded to company servers. [8]

According to the company, encryption keys remain under user control, meaning that Tresorit and third parties cannot access the content of stored files. [9]

Security challenge

edit

Between 2013 and 2014, Tresorit organized a public challenge inviting security researchers to attempt to compromise the service's encryption implementation. The challenge received coverage in technology and cybersecurity media.[10]

Acquisition by Swiss Post

edit

In 2021, Swiss Post Communications Services acquired a majority stake in Tresorit as part of Swiss Post’s broader digital services strategy.[11]

Reception

edit

Tresorit has been covered by international technology and business publications in the context of secure cloud storage and encrypted collaboration services.

TechCrunch described the company as an early European provider of end-to-end encrypted cloud services, while The New York Times included it in discussions of secure file-sharing tools.[12]

Other publications such as TechRadar and ITPro have reviewed Tresorit in the context of enterprise security and confidential data handling. [13]
