Firewall Sizing Calculator reliable?

Question

There is the Sophos Firewall Sizing Calculator available at https://firewallsizing.sophos.com. However, it seems to provide rather rudimentary and sometimes incorrect results. For example, if I enter a value of 20 Mbps in IPSec peak throughput requirements (Mbps), I am still recommended firewalls that, according to the datasheets, do not meet the required IPSec throughput. Some important requirements, such as the number of REDs, are not even queried. It seemes as if a student hat set it up. Is this calculator even usable?

Hi drimalski, 
 Thank you for reaching out to Sophos Community. 
 If the Sizing Calculator hasn&rsquo;t met all of your expectations, I recommend manually contacting your Sophos Partner/Account Manager to have you further assist with all of your requirements.
