SSH Sercure Shell (SSH)

I'm currently using this application at work and finding it quite good.
As the name suggests the SSH Secure Shell for Workstations Windows client (SSH2 client) is a program that allows secure network services over an insecure network.

The SSH Secure Shell for Workstations Windows client replaces other, insecure terminal applications, such as Telnet and FTP. It allows you to securely remote login to remote host computers, to execute commands safely in a remote computer, and to provide secure encrypted and authenticated communications between two untrusted hosts. X11 connections and arbitrary TCP/IP ports can also be forwarded over the secure channel, expanding Secure Shell 2's usability even further.

Secure Shell 2 with its array of security features is a great tool for a network environment. It is a powerful guardian against the numerous security hazards that nowadays threaten network communications.

As a database administrator I have been using this application a far bit.
