First. I downloaded and installed other VPN apps several months ago. I had downloaded several and they did not work out very well at all. Then I decided to give Pro XPN a try. And there it was up and running and it was secure AND Private. Unless one has the private addressing you are using they are unable to find you let alone listen. Some times this method is called a "point-to-point tunneling protocol." We are in the tunnel and no one knows or cares you are there. Pro XPN has the best software for VPN Communications on the Planet!! In addition they have the customer care effort to match! Warning! You will fall in love with the proXPNs application and when the need arises a level of customer care to match! Definitely worth every penny of the investment!
