Proton Drive vs. Prot-On

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.

All iterations of the document will be protected with strong encryption regardless of their storage location, be it on personal devices, cloud platforms, or USB drives. Whenever users try to access the secured document, Prot-On will confirm their authorization and the specific access rights they possess.

This process guarantees continuous protection of document security throughout its entire lifecycle, ensuring that sensitive information remains safeguarded against unauthorized access. Furthermore, this level of oversight allows users to feel confident in sharing their documents, knowing they can maintain control over their data.
