About Proton Drive
Proton Drive is the end-to-end encrypted cloud storage service from Proton, the Swiss privacy company behind ProtonMail. Every file is encrypted on your device before upload (not even Proton can access your data), and shared links can be password-protected with expiry dates. It includes Proton Docs and Sheets for encrypted real-time document and spreadsheet collaboration.
Available on web, Windows, macOS, iOS, and Android, Proton Drive syncs files automatically via a desktop folder. 5 GB of free storage is included with every Proton account, with upgrades that bundle Mail, Calendar, VPN, and Pass. An open-source codebase allows independent cryptographic verification by any researcher.

- Client-side E2E encryption that encrypts files before they leave your device
- 5 GB free storage with every Proton account, no credit card required
- Password-protected sharing with configurable expiry on shared links
- Automatic mobile photo backups with encrypted collaborative album sharing
- Proton Docs and Sheets for encrypted real-time collaborative document editing
- Desktop sync folder on Windows and macOS for automatic file synchronisation
- Open-source code for independent cryptographic audit by the community
Proton AG is headquartered in Geneva, Switzerland, which operates under some of the world's strictest privacy laws, outside U.S. and UK jurisdiction. The service is GDPR-compliant, holds ISO 27001 certification, and is audited by independent security researchers. Switzerland's constitutional privacy protections and absence of mandatory data retention laws provide a legal framework stronger than most EU alternatives.
Part of the Proton ecosystem trusted by over 100 million users worldwide, from journalists and activists to enterprises requiring sovereign data storage.
Why choose Proton Drive over Box?
The decisive argument is data jurisdiction. Box is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Proton Drive removes that overhead. As a Switzerland-based provider, it operates under Swiss FADP + GDPR for EU users, and data stays in Switzerland, which the European Commission recognises as offering an adequate level of protection. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
