Proton Drive

From the creators of Proton Mail, Proton Drive is a Swiss-based, end-to-end encrypted storage service that integrates with the broader privacy-focused Proton ecosystem. It currently offers secure file storage and sharing via web and mobile, with desktop clients in development. It targets existing Proton users and anyone seeking a privacy-first cloud from a trusted name. As a newer service from a reputable provider, it shows strong promise but is still building out its full feature set compared to established players.
