## Concept

Ticket Guardian has a simple layout but powerful concept. It works based on **rules.**

**Rule** is a regular text / string that Ticket Guardian will scan for presence in Public response. If it is found - it will prevent the submission of the ticket (changing status) with a notification, informing which rule has caused prevention.

Simple put it - if your public reply contains text that you asked Ticket Guardian to find, it will prevent you from sending a response to the end-user, which in some cases can save end-users' frustration.
