What is Proton Drive?
Proton Drive is a secure cloud storage and collaboration platform built for professionals who manage sensitive data.
Whether you’re sharing internal documents, legal contracts, or client files, Proton Drive keeps your data private — by default.
Files are encrypted on your device before upload, and only you and your collaborators can access them. Even Proton can’t read your files. You can set passwords, add expiration dates, or revoke access instantly — so you’re always in control.
Each user gets 1 TB of storage, with the flexibility to add more as your team or projects grow.
Designed and hosted in Switzerland, Proton Drive is developed by the team behind Proton Mail and Proton VPN — trusted by over 100 million users worldwide. We’re independent, open source, and committed to keeping your data safe from surveillance and vendor lock-in.
Proton Drive helps you stay compliant, with support for:
- GDPR, HIPAA, ISO 27001, NIS2, and DORA
- Verified SOC 2 Type II audits
- No complex setup. No third-party tools required.
Built for security teams, law firms, healthcare providers, consultancies, and privacy-conscious organizations of all sizes.
