Tresorit is a Swiss-based, end-to-end encrypted cloud where encryption keys stay with the user, so not even Tresorit can read your files. Business Plus and Enterprise plans let you choose the data-residency region for your files.
Widely used by regulated industries, it is enterprise-grade E2E storage built for firms that need data-residency guarantees, and while it can be overkill for casual personal use, it is a serious European alternative to Dropbox and Google Drive for compliance-heavy teams.
