Proton Drive – European cloud storage
End-to-end encrypted cloud storage from Proton AG in Geneva. Zero-knowledge architecture means even Proton cannot access your files. Own servers in Switzerland and Germany, ISO 27001 certified. Part of the Proton ecosystem alongside Mail, VPN, and Pass.
Quick facts
Zero-knowledge encryption means even Proton itself can't read your files, and it slots straight into the same login as Proton Mail, VPN and Pass if you're already in that ecosystem.
It's a newer product than Proton Mail, so features like advanced sharing controls and desktop sync are still catching up to more established competitors.
Why does it score 95?
Incorporated in Geneva, Switzerland – an EFTA country rather than a full EU member state.
Owned by the non-profit Proton Foundation rather than private investors, though it sits under the wider Proton group rather than standing fully independent.
Proton Drive runs on Proton's own servers in Switzerland and Germany, and the company has been diversifying infrastructure into Germany and Norway in response to proposed Swiss surveillance law changes.
Fully open source, GDPR-compliant, and ISO 27001 certified – a thoroughly verified trust record.
