Issue/Introduction

Is FTPS or SFTP is supported on the ProxySG?
You want to know if FTPS or SFTP is supported

Resolution

Blue Coat does not support SFTP support (Secure FTP).
Blue Coat does support FTPS (FTP over SSL) for access log uploads.

Note: It is possible to tunnel FTPS and/or SFTP through the ProxySG by creating a "TCP-Tunnel" service on the port used by the application. However, since the proxy is unable to inspect or modify the secure FTP communication, there are limitations in tunneling the data port. It may be more feasible to bypass the proxy for these protocols.

Additional Information

The above applies to transparent mode. SFTP in explicit mode, however, is possible. See the following article for details:
