# Sidewinder SSH Proxy

The Sidewinder SSH Proxy allows you to restrict the types of traffic and the commands that can be used with SSH connections.

For example, you can use the Sidewinder SSH Proxy to block port forwarding or to restrict the commands allowed in file transfers using the SSH protocol.

You can also use the Sidewinder SSH Proxy to enforce encryption strength for the connections. In the Protocol Parameters, you can separately specify the key type and key length for each side of the connection. The Client Advanced Settings define settings for connections between the Sidewinder SSH Proxy and the client. The Server Advanced Settings define settings for connections between the Sidewinder SSH Proxy and the server.
