what protocol does the bluemix secure gateway and client use to communicate?

Question

I see from this article that there is a gateway tunnel created between client side and server side.

Would it be safe to expose the secure gateway client to all?

Answer 1

The Secure Gateway Client establishes the connection to the Secure Gateway Server over HTTPS using TLSv1.2. Once this connection is established, the SG Server will set up the listeners for your gateway's destinations on the associated cloud host:port combinations (details dependent on the configuration of each destination). Connecting to these listeners is the only way to pass information from the public network via Secure Gateway to the private network where your SG Client is located.
