Filen vs Tresorit
Side-by-side comparison of features, pricing, ratings, and alternatives.
Filen is a German cloud storage provider built around AES 256-bit client-side encryption and a zero-knowledge architecture, meaning the company itself cannot read stored files. Alongside standard file sync and storage, it offers a network drive that mounts cloud storage as a local drive, encrypted notes with markdown support, and end-to-end encrypted chat. Filen's applications are open source, and the service supports WebDAV and S3 protocols along with a headless CLI for developers and automation. It is positioned as a security-focused alternative for individuals and small teams who want full encryption without losing everyday usability.
Tresorit is a cloud storage solution designed for businesses that require high levels of security and data protection. It uses zero-knowledge encryption, which ensures that only the user has access to the data, and not even Tresorit's employees can access it. This makes it an ideal solution for businesses that handle sensitive data, such as financial information, personal data, or confidential documents.
