Issue

How can I secure my file transfers?

Solution

For PASSPORT PC to Host and PASSPORT Web to Host:

PASSPORT features SSL (FTPS) and SSH (SFTP) secure file transfer.

FTPS provides a secure file transfer through the use of the SSL layer, found below the standard FTP protocol, and encrypts the control and/or data channels. PASSPORT FTP implements FTPS according to IETF RFC 4217 Securing FTP with TLS. PASSPORT connects to a standard FTP server port 21 and begins an unencrypted FTP session as it normally would, then requests that SSL security be used through the AUTH TLS command and performs the necessary SSL handshaking.

PASSPORT also supports SSH File Transfer (SFTP). SFTP relies on the SSH protocol to provide secure file transfer. The PASSPORT SFTP is based on the PuTTY SSH implementation for Win 32.
