I used NIS for years, but switched to KIS a few years ago when NIS seemed to be having significant performance problems. While KIS has proved to be a pretty good product, I have been looking for a reason/opportunity to switch back ot NIS. Based on what I have read about NIS 2010, this may be the time since my licenses come up for renewal in a couple of months.
My one hesitation is the mediocre leaktest results. If I remember correctly, prior to NIS 2009 it was terrible so mediocre was a big improvement. I'm hoping the NIS 2010 results will be even better. Does anyone know how Matousec sets their review schedule? From what I read on the site it almost seems like it may be partially driven by vendors being willing to pay for the testing.
