Each vulnerability will have a rating indicating how critical it is to fix. This is based on a combination of factors, depending on the Rating Methodology that has been selected for your assets.
WhiteHat Sentinel offers the choice of two rating methods: Advanced and Legacy. New customers will have the Advanced methodology selected by default, but any user with Admin authority can set the Rating Method for the customer.
The vulnerability rating, based on the Rating Methodology chosen, will be displayed in a variety of locations in the User Interface under the label "Rating."
To change your rating methodology, see Changing Your Rating Methodology.
