Proton Drive is an end-to-end encrypted cloud storage service from the team behind Proton Mail. Based in Switzerland, it encrypts both files and metadata before upload, ensuring even Proton cannot access user data. As part of the broader Proton ecosystem (Mail, VPN, Calendar, Pass), it offers a unified privacy-focused platform with a free tier and competitive speeds.
Proton Drive leverages the trusted Proton brand to compete against established encrypted services like Tresorit and MEGA, as well as mainstream storage like Google Drive. Its free tier and ecosystem bundling create a strong acquisition funnel. The product is newer than competitors and still building out features, but its privacy reputation accelerates adoption.
Stronger enterprise features with ISO 27001 certification and advanced compliance tools. Higher pricing targets regulated industries. More mature product with broader business integrations.
One-time purchase option and built-in media player. Encryption is a paid add-on. Better for media-heavy users who want lifetime ownership over subscriptions.
Deep Google Workspace integration with 15 GB free. Superior collaboration and search but no end-to-end encryption. Dominant market share.
Larger free tier (20 GB) with default encryption. Longer track record in encrypted storage. Includes chat and video calling features.
Proton Drive benefits from bundling with Mail, VPN, Calendar, and Pass. Users already in the Proton ecosystem adopt Drive naturally, creating cross-product retention that standalone storage services cannot match.
Encrypting file metadata (names, sizes, types) in addition to content is rare among competitors. This deeper privacy protection appeals to security-conscious users who understand that metadata can be as revealing as content.
As a newer product, Proton Drive still lacks some features that Tresorit and pCloud offer. Rapid feature development is critical to retain users who try Drive through the ecosystem bundle but need advanced functionality.
Yes, Proton Drive offers a free tier with encrypted storage. It also comes bundled with free Proton Mail, VPN, Calendar, and Pass accounts. Paid plans offer more storage and additional features.
Proton Drive uses end-to-end encryption for both files and metadata. Data is encrypted on your device before upload. Swiss jurisdiction provides additional legal protection. Even Proton cannot access your files.
Proton Drive prioritizes privacy with end-to-end encryption; Google Drive prioritizes collaboration and ecosystem integration. Google offers more free storage (15 GB) and better productivity tools. Proton Drive is better for privacy-conscious users.
