When you say customer browser, do you mean the users on the enterprise network behind the firewall, all within the control of the enterprise that owns the data? I think this is what is meant since the Internet sessions from customers could be terminated at a load balancer on the enterprise edge and then this extension may be used between servers internal to the enterprise and from what you are saying, browsers as well. Or is the plan for this to be opt-in from the customer external to the enterprise (I didn't think that was the case and it would be good to clarify). This distinction would be helpful to know where traffic may be intercepted if there were another party that might be malicious.
