SAP Router with SNC security question (For third party connectivity)

Hi,

We are going to use separate SAPRouter with SNC for third party connection.Already we had SAPRouter (without SNC) for SAP Connectivity. The new is separate for thirdparty connection.

I have one question in my mind. How SAPGui / users connectivity will happen, if many users are logging in. Is that all the users connection come through only SNC with secured encryption ?

Or the data transfer will happen without encryotion format ? Experts can clarify on the same. Thanks in advance.
