Fugu is a graphical frontend to the commandline Secure File Transfer application (SFTP). SFTP is similar to FTP, but unlike FTP, the entire session is encrypted, meaning no passwords are sent in cleartext form, and is thus much less vulnerable to third-party interception. Fugu allows you to take advantage of SFTP’s security without having to sacrifice the ease of use found in a GUI. Fugu also includes support for SCP file transfers, and the ability to create secure tunnels via SSH.

Pros: Fugu is easy to use and significantly faster than most SFTP clients.

Cons: “The SFTP client Fugu wraps does not know how to delete folders recursively. This means that it will give you an error if you try to remove a folder that is not empty. Delete the items in the folder first, then delete the folder.” Added by fuzzy_logic: It doesn’t support standard FTP.
