Secure Pipes is described as 'makes managing SSH tunnels simple and robust. It's made for people who love and understand UNIX technology, but also love the simplicity and convenience of Mac OS X'. There are three alternatives to Secure Pipes for Mac, Windows and Linux. The best alternative is Core Tunnel, which is free. Other great apps like Secure Pipes are iTivity SSH Manager (Free) and SSH Tunnel Manager (Free).
Core Tunnel is the best way to manage your SSH tunnels, with OS X Keychain integration. You can manage multiple tunnels in parallel, supports password/keyboard/pubkey authentication methods, creates local/remote/dynamic port forwarding tunnels & more.
SSH Tunnel Manager is a tool to manage SSH Tunnels (commonly invoked with -L and -R arguments in the console). With SSH Tunnel Manager you can set up as many tunnels as you wish, each one containing as many port redirections as you wish.
