Hi Aaron,
Just be careful when comparing. Firstly when coming up with a specification, always try to obtain the "real" throughput of the environment. You may find a 100Mbps circuit but in reality may be only touching 50 at peak. In which case you could possibly spec lower than the equivalent firewall your replacing.
Also the stats that you are referring to, is this raw firewall throughput with no threat prevention, no matter, etc? I've seen vendor spec sheets before and a lot of them will be stripped back for the purpose of the spec sheet, so no NAT, no Https inspection etc.
In addition what level of protection would you want from the Check Point? Which blades would you plan on using? As these will all be factors when considering which appliance to go for.
Regards
Mark
