Sizing for Fortigate Proxy (500 user)

[Mattias]

Hi there,

which Fortigate model would you chose for the following requirements?

- Fortigate "only" acts as Explicit (web) Proxy with 500 concurrent users

- A/P cluster

- 100 Mbit Internet

- FSSO authentication

- Full set of security features (Application Control, IPS, Webfilter, Antivirus (flow based) and Deep SSL-Inspection)

- Full logging to FortiAnalyzer

I have a device in mind but I'd like to know what you would size.

Thanks and best regards,

Mattias
