Proton Drive is a cloud storage service built around end-to-end encryption, meaning files are encrypted before they leave the user's device and the provider itself cannot read their content. It covers the core functions of a cloud drive: uploading and storing files of any size, syncing a desktop folder with the cloud, and accessing content from Windows, macOS, Android, iOS, or a web browser.
Sharing is handled through links that can be password-protected and set to expire, which is aimed at users who want more control over who can access shared files than a typical public-link model offers. The service also includes automatic photo backup from mobile devices with support for shared albums, plus Proton Docs and Proton Sheets, in-browser editors for creating and collaborating on documents and spreadsheets without leaving the encrypted environment.
Proton Drive is best suited to individuals and organizations that prioritize data privacy and are willing to trade some of the deeper third-party app integrations of mainstream cloud drives for an encryption-first design. A business tier adds per-user storage and compliance-oriented features for teams.
The service is part of the wider Proton product suite (also known for Proton Mail and Proton VPN), and some of the higher paid tiers bundle storage together with other Proton services rather than selling drive storage alone.
