Tresorit

Swiss zero-knowledge encrypted cloud storage, positioned as the alternative to Dropbox for regulated industries (legal, healthcare, finance). Distinctive for end-to-end encryption where even Tresorit can't read your files, plus EU-based data residency and GDPR compliance built in. Priced higher than mainstream storage ($15-$30/user/mo) — the premium is the encryption guarantee. Popular with law firms and consultancies handling sensitive client data.
