Blue Coat's unique Web filtering technology divides Internet content into more than 55 distinct categories. These categories are stored in the master Blue Coat database, through which we maintain and update more than eight million ratings of websites and domains. A Web site will fall into one or more of these categories, based on the content of the site. To meet your particular needs and preferences, you can configure the software to block or allow specific categories.
