The only reason to use third part CheckPoint log analyzers is the price. Some of the third part products is 10 times cheaper. I do not think that any other product will dig logs better (and most probably friendly) than integrated CheckPoint solution (Eventia Reporter)
adventnet.com products are VERY sweet (and almost FREE!). Our customers just fall in love into NetFlow analyzer (for cisco routers). I did not tried Firewall analyzer. We can all go to "Live Demo" section and try it (
http://manageengine.adventnet.com/pr...all/index.html -> Live Demo).
Ask for help on the adventnet.com forums. Support fellows on the forum are very obliging.
