Now If i may add some more 'fun' to this thread. One reason why cisco didn't
compete in this bake off 'could' of been because their firewall performance
decreases significantly when major FW functionalities are turned on for
example NAT or even passing small packets. Or they are big enough that
they really could careless about small bake offs such as these. They'd much
rather play the corporate political card and strong arm than winning
technicaly in my experience...

Anyone wonder why cisco never publishs #'s for their fw / asa/isr w/ small
packets or mixed packet size?

Also most 'independent' testers such as tolly or other groups are paid/for
hire.

And yes i also used to work w/ multi vendor fw's everyday

This is more fun than i thought. This FW bake off is from 2005!!! and yes i know the PIX is replaced by the ASA and yes i was talking about market share or according to Gartners magic quadrant for fw's.
