Encrypted cloud storage
Proton Drive is easy-to-use encrypted cloud storage. No one can access your files without your permission.
End-to-end encryption for all your files
Proton Drive is truly private cloud storage. Our end-to-end encryption means no one, not even Proton, can access your files and folders or see their names without your permission.
Proton Drive also supports end-to-end encrypted file sharing. Only the people you share the link or password with can access your files, keeping you in control.

Secure file sharing
Proton is based in Switzerland, which provides us with many legal privacy protections. Switzerland is politically neutral, outside US and EU jurisdiction, and isn’t a member of any Five Eyes or Fourteen Eyes intelligence-sharing agreements. End-to-end encryption is protected under Swiss law, and under Article 271 of the Swiss Criminal Code, Proton is prohibited from sharing data with foreign authorities
Encrypted storage for organizations
Proton Drive secures the information of organizations all around the world. Our clients include journalists, activists, and businesses with high-security needs. By using Drive, you can securely store and share files within your organization while maintaining control over permissions and data access.
Data stored on Drive is accessible only to your organization and anyone you share it with. Our end-to-end encryption means that Proton cannot read the files stored in your organization’s Proton Drive account. Even if we suffered a data breach, your files would remain securely encrypted.
Together with Proton Mail, Proton Calendar, and Proton VPN, Proton provides a powerful suite of privacy-focused services.

Additional security features
On a system level, our servers utilize fully encrypted hard disks with multiple password layers, preserving data security even if our physical infrastructure is breached or stolen.
This reduces the risk that illegitimate Proton certificates are issued and used to compromise your security.
24/7 security and monitoring
This includes warning you if an advanced attacker is targeting your account and automatically locking your account if we suspect somebody other than you has gained illicit access.
Proton Drive was built by the team behind Proton Mail, the world’s largest encrypted email service
