Yes this one is really good !!.
Here in our office we use Palo Alto Networks PA-3020 Next Gen Firewall it's is really good product after all the price is not that low.
And we are still waiting to get traps but in the Firewall you have something like traps but on network level.
I am not the system administrator and i cannot say to much about how is working or etc ...
I know only that is not that ease to config . like you need some to take some courses form Palo Alto before using it ..
