Sizing Fortigate

[NgocNguy]

I want to use Fortigate and Fortiweb to proctect Webserver and database server. But I don't know exactly how to calculate thoughput to choose the best appropriate one.

1/ I have seen in Dataseet of fortigate (such as FG200D), it indicated some specifications such as: Firewall throughput, IPS throughput, SSL inspection throughput. What does it mean ?

2/ For an example, I have 20000 users from internet. They use web browser to access webservers (in datacenter) with https.

- So how can I calculate total throughput for https traffic  in this case ?

- How much byte for each connection https?

Hi Ngoc,

Usually that's what the pre-sales from the partner or distributor is here for.

Regarding the specs found in datasheet, they are based on internal tests that have been made by Fortinet.

If you have access to it, from the partner site you may use this tool : https://competitive.myfortinet.com/product_sizing

If you don't have access to it, I'd recommend talking to a partner.

Regarding Firewall/IPS/SSL throughput, this is regarding what inspection you want to ask your Firewall to perform:

Firewall: basic L4 matching (ip+port and no UTM)

IPS : app control or IPS activated (no SSL decryption)

SSL inspection : SSL is decrypted
