if you're a partner you can use 'popsicle' from the NextWave portal


to get a decent sizing you'll need to estimate how much ipsec, app-id and ssl throughput you will expect, and then guesstimate how much l7 scanning you're going to apply



1gbps app-ID sizes to pa-820,

1gbps threat-ID sizes to pa-3220,

1gbps ssl decryption + threat-ID sizes to pa-5220

Hi @reaper 

Can you please  elaborate How I determine the app-id throughput

Here is a link to the comparison sheet:

Then select the devices you think might work. In your case, start with the 3410 and 5410 as a comparison.


I always look a the smallest number and go from there, even if I'm not using it. This way if in the future you need that feature, you have it sized correctly, if nothing else changes. Also dont skimp on the licenses and features. They help you more than you know.


I'm only guessing but I bet a 3410 would work for you (but dont go by my advice only since I dont know your environment). Stay with the models that have the 4 as the second number, they are the newest architecture.
