We are evaluating it now. It looks like a good package.
The GUI interface is really nice - I haven't seen any other
firewall software as easy to use. Now the bad part; the
manual is so bad they might as well not include one.
Also the pricing is arbitrary and not based on value. You
can pay around $5k if you have less than 50 nodes or $20k if
you have more.
Since the firewall only "sees" the machines it is
controlling security on (or the routers) it seems nutty to
me to base the price this way. It seems to say "we can get
more money from people with large networks without
delivering additional value". Just my .02. Again, overall
it looks like a good package.
