A short list of SOCKS Clients that I have used or know of
Note that many programs have their own SOCKS client built in, many FTP clients such as Filezilla, WS FTP, Firefox and so on have built in support. You really need a client when you have an application that must use a proxy server, but the application does not have proxy support.
Commercial Client for Windows and MAC
Excellent and well known SOCKS client. Been around for many years as part of the their eXceed X Windows implementation. As far as I can tell, the client is free but still under license and support. I haven’t been able to test with this.
Free version of what is now Widecap. Works OK but some people have reported reliability issues. Limited functionality – see Widecap below
Commercial version of Freecap with a lot of extra features.
Now defunct. Bought by Blue Coat and the client was discontinued.
Windows Internet Explorer
Windows IE supports SOCKS proxy. Obviously, this means that IE can use a SOCKS proxy which is useful for testing the configuration on your ProxySG
Mac OSX native
OS X has SOCKS configuration support, but only for software that is programmed to the call the SOCKS method.
Proxifier has a Mac OSX version.
