Intercept X - Network Threat Protection module blocking web form

Hi, first time poster here. 

As per the title, the Network Threat Protection module part of Intercept X is blocking a simple webform on our website. I have added an exception for this, in Sophos Central, so now our users can test and use this form however we'd like to get an understanding of why the form was blocked in the first place so we can fix any underlying issue with the code/form. Is there anywhere in Sophos Central that can provide more detailed logging of blocked items? 

In doing this we hope to fix the form so other AVs don't incorrectly block it and prevent our users/customers from submitting on the form.

TIA.
