Proton Drive, developed by Proton AG (the creators of Proton Mail), is a secure cloud storage service that provides end-to-end encrypted (E2EE) file storage, sharing, and synchronization. It supports the workflow of securely uploading, organizing, accessing, and sharing files and folders, ensuring that data remains private and protected from unauthorized access. Accessible via web browser, with dedicated desktop apps for Windows and macOS, and mobile apps for iOS and Android, ensuring encrypted access across devices. Its most-used feature is likely the secure file upload and storage, where users can simply drag-and-drop files into their encrypted drive, knowing they are protected by E2EE. All files are end-to-end encrypted on the user's device before being uploaded to Proton's servers in Switzerland, meaning Proton itself cannot decrypt or access user data.

Why It’s Useful
Proton Drive eliminates the significant privacy and security risks associated with traditional cloud storage providers that can access user data, providing true peace of mind through client-side encryption. A privacy-conscious individual can store sensitive personal documents, family photos, and financial records, knowing that only they hold the encryption keys and their data is safe from surveillance. A small business owner handling client contracts, intellectual property, or medical records can use Proton Drive to securely store and share these files, complying with strict data protection regulations. It offers a free tier with 1 GB of storage. Paid plans, often bundled with Proton Mail, VPN, and Calendar, start from €4.99/month for 500 GB (Proton Unlimited). Its unwavering commitment to end-to-end, zero-access encryption sets it apart from major competitors like Google Drive, Dropbox, and OneDrive, which typically use server-side encryption and can technically access user data. Advanced users can leverage secure file sharing with password protection and expiry dates, integrate with other Proton services for a comprehensive privacy ecosystem, and utilize version history for critical documents. The learning curve is low; the interface is clean and intuitive, similar to other cloud storage services, making it easy for anyone to use immediately.
