End-to-end encryption

With Proton Drive's end-to-end encrypted cloud storage, no one but you and the people you choose can access your files — not even Proton.

Proton Drive’s end-to-end encryption ensures that your files, their names, and more are all fully encrypted at rest and in transit to your secure cloud. Unlike Big Tech, Proton can't access your files, so your data remains fully owned, accessible, and controlled by you.

Swiss privacy

Proton is based in Switzerland, so your files are protected by some of the strictest privacy laws in the world.

Stay in control of shared files

Proton Drive's end-to-end encryption also works when sharing files and folders.

Optional features like password-protected files and expiring file-sharing links enhance security even further. Best of all, there are no file size limits.
