SFTP using webMethods

Hi,
I have some doubts regarding SFTP.
How does SFTP exactly works with webMethods?
Does webmethods support SFTP ?
As far as I know webMethods prefers to use FTP thru VPN and does not provide full SFTP support.
Has any one implemented SFTP using webMethods ??
Appreciate quick response.

Thanks
