Customizable Block message
I would like to know how to customize the Block message header used in Response Rules for Endpoint? I am able to modify the message in the alert box and I'm familiar with the check boxes, however I would like to change the header.
By default, it reads: Blocked: confidential data detected.
I may be asking for too much here, but I would like to edit the header as well as add a company style logo as well.
