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.
Mega offers cloud storage that emphasizes privacy through client‑side encryption, ensuring only you can access your files. Users start with 20 GB of free space and can upgrade for more capacity and features. The service includes a web interface, desktop sync clients, and mobile apps, making it easy to upload, share, and collaborate on files across devices while keeping data encrypted in transit and at rest.
