Our verdict
Proton Drive is end to end encrypted cloud storage from Switzerland, letting people back up files, reach them from several devices and share them with chosen recipients. For users who want file storage where just the owner and the people they pick can open the contents, it is a sensible match.

Encryption and access control
Files are protected with end to end encryption, so the contents are unreadable to anyone without the right keys, including the provider itself. Sharing can be limited with passwords and expiry dates, and access can be withdrawn at any time. The service is built and based in Europe, where European privacy laws apply, and it holds the ISO 27001 information security standard. Teams that need more control over company data can use the business version of the service.
Sync, photos and collaboration
Files sync automatically between a desktop and the cloud, so the latest version is available on each device. Mobile backups keep photos and videos safe, and shared albums let people relive favourite moments together. Encrypted spreadsheets include built in formulas and charts, while an online document editor lets several people write and edit at the same time with privacy kept in place. These tools suit everyday personal and team use alike.

Frequently asked questions
Where is the company based?+
The company is based in Switzerland and operates under the legal name Proton AG. The service is built and based in Europe, so it is protected by European privacy laws, which apply alongside its own security design for stored files.
Can the provider read stored files?+
The provider cannot open stored files because of the zero access and end to end encryption used across the service. Access stays with the account holder and the people they choose to share with, so even the company running the platform cannot view the contents.
What kinds of files can be stored and shared?+
Any kind of file can be stored, including photos, documents and spreadsheets, and it can be shared with anyone. Sharing can be controlled with passwords and expiry dates, which helps keep sensitive work in the right hands and makes the arrangement easy to adjust.
