Maybe you haven't decided to switch to a more secure solution because you use Windows Servers and Windows hasn't adopted using SSH.
Maybe you think SSH is only for Unix/Linux.
Well, your excuses are no longer good here sonny boy. If you haven't heard there is an OpenSSH port for Windows. Now you can still use the terminal remote access method, but you won't be sending your login credentials and important information across the wire in plain text.
OpenSSH provides full support for SSH/SCP/SFTP. So what are you waiting for? Download OpenSSH and secure your servers.

OpenSSH for Windows
OpenSSH for Windows is a free package that installs a minimal OpenSSH server and client utilities in the Cygwin package without needing the full Cygwin installation. This is similar to the package formerly available from NetworkSimplicity.
The OpenSSH for Windows package provides full SSH/SCP/SFTP support. SSH terminal support provides a familiar Windows Command prompt, while retaining Unix/Cygwin-style paths for SCP and SFTP.
