Proton Drive is a file storage solution that combines the convenience of the cloud with the privacy of a Swiss vault. With Proton Drive, you can easily access your data, while also benefiting from end-to-end encryption.

With Proton Drive, your files are accessible 24/7 from any device and secured with automatic backups in multiple datacenters. Your data remains safe even if you lose your phone or computer.

However, our cloud still protects your privacy. Our end-to-end encryption means that unlike other cloud storage solutions, you don't have to share your most intimate files with a third party. Unlike Big Tech, Proton can't access your files. Your data remains fully owned and controlled by you.


Encrypted cloud storage for all your files

Proton Drive's strong encryption goes beyond other secure cloud solutions. End-to-end encryption ensures that no one, not even us, can access your files. Files, file names, folder names, and more, are all fully encrypted at rest and in transit to the secure cloud.
