I have been running Sygate pro for years but currently trying ESS. Using ESS on Interactive filtering mode it closely resembles Sygate in behaviour. Have tried a number of leak tests with both and found comparable though slightly different results. Would appreciate any comments as to the differences. I am thinking of giving up Sygate because I already run NOD 32 antivirus and because Sygate is no longer supported or updated though it still continues to work. What do people think?
