SSH is a multi-purpose protocol for secure system administration and file transfers. It is included in every Linux and Unix system.
Windows Client Alternatives
The following clients are widely used:
- PuTTY (Free, Windows)
- Tectia SSH (Commercial, comes with support & key management ready)

It is a distinct code base from the open source version, is supported for key management on all platforms, and comes with 24x7 support.
