is MWG7 able to do dynamic URL categorization according to the web site content or keywords in URL? That means mainly the situation if there is no record in on-box URL database or in GTI cloud.
not yet, unfortunately. I think we have planned this for the future, but as of today we do not have this feature in MWG7. In MWG6 we have the Real Time Classifier, which is able to perform on-the-fly categorization.
