Securing Xymon Over Internet

Hi XyMonsters!

I need to monitor several satellite sites with XyMon. These sites are not available on our local LAN so I have to go via the internet. I am a bit hesitant to open the ports etc since the information collected can be used in foot printing the system. How would I go about securing the service so that xymons information does not fall into the wrong hands?

Regards

Neil
