Budapest, Hungary · Startup Tresorit is a Budapest-founded end-to-end encrypted cloud storage and file-collaboration company that positioned itself very early as the privacy-first European alternative to Dropbox and Google Drive for regulated industries: law firms, healthcare, financial services, and — notably — government and defense teams in Europe that cannot legally store sensitive files with US hyperscalers. Founded in 2011 by István Lám, Szilveszter Szebeni, and György Szilágyi, the product is built around zero-knowledge client-side encryption, so files are encrypted before they leave the user's device and Tresorit itself cannot read them even if compelled. The company famously ran a public one-million-dollar hacking challenge to demonstrate the robustness of its encryption, and has since been repeatedly cited by European regulators and data-protection authorities as a model for GDPR-aligned cloud collaboration. In 2021 Swiss Post acquired a majority stake in Tresorit as part of its digital sovereignty push — one of the most strategically significant Hungarian deep-tech exits.
