As you know, our number one priority is the security of those transfers. We enable the safety of our systems by reducing our attack surface, as we in the trade call it. We have a very small, close-knit group of members whom we support and allow into that network. That network is very segregated from other networks, and that small attack surface allows us to pay very close attention to what happens on it in identifying threats, monitoring the activities and responding to the things that occur there in real time.
