Apps similar to CNTLM include WinFoom, which is free and open source. Other options are Px proxy and Corporate Proxy Helper. In total there are three apps like CNTLM for Windows, Linux, Mac and Chrome OS.
Winfoom is a HTTP(s) proxy server facade that allows applications to authenticate through a NTML/Kerberos/SOCKS/PAC file authenticated proxy server, typically used in corporate environments, without having to deal with the actual handshake.
Enable any application to authenticate through a proxy server with NTLM or PAC proxy scripts with ease! Say goodbye to hours lost in corporate environments trying to get the proxy and SSL configuration correctly. Best alternative to CNTLM!.
