Zero-knowledge storage built for regulated businesses (ISO 27001, HIPAA).
Why it beats Dropbox. For organizations bound by HIPAA/GDPR, Tresorit delivers zero-knowledge encryption plus the certifications and data-residency control Dropbox's server-side-key model can't match — so a breach or legal demand can't expose readable client files.
| Dropbox | Tresorit | |
|---|---|---|
| Can the provider read your files? | Yes (holds the keys) | No (zero-knowledge) |
| Zero-knowledge by default | No | Yes |
| Encryption model | Server-side encryption with Dropbox-held keys on core sync; optional end-to-end only on some Teams folders. | End-to-end, zero-knowledge by default; granular admin controls and compliance tooling. |
| Legal jurisdiction | United States (CLOUD Act applies) | Switzerland / EU (Hungary); multiple data-residency regions. |
| Notable breaches | 2012 breach (~68M credentials), 2024 Dropbox Sign breach, 2022 GitHub repo theft | No major breach reported |
| Free tier | 2 GB | Limited free / trial |
| Open source | No | No |
| Independent audits | SOC 2 / ISO (not zero-knowledge) | Yes — ISO 27001 certified, regular external audits; HIPAA support |
Healthcare, legal, and financial teams that need zero-knowledge plus compliance certifications and data-residency choice.
Best for teams: provision Tresorit, set data residency, migrate shared folders, then decommission the Dropbox Business workspace.
