Facts checked 8 Oct 2026

In short

Filen suits people who want end-to-end encryption on every file, open-source code and a cheap annual plan1,2,8. It has a network drive, sync modes and password-protected links4,9,10. The catch: Filen does not publish an outside security test, a certification or file-version retention times, and it no longer runs a public bug bounty3,13.

Best for: People who want every file end-to-end encrypted, open-source apps and a low entry price.
