Securing the Client from Prying Eyes I had an experience on the train the other day which got me thinking. In our current age of always on and connected, we find ourselves working in various public places. Coffee shops, the train, an aircraft, wherever. You can get internet now basically anywhere and with the propagation of VPN’s and Two-Factor authentication we can also work anywhere.
