Multilayer Internet Content Filtering

PureSight offers an innovative multilayer filtering approach by combining the PureSight Active Content Recognition (ACR^TM) core technology into a pre-classified database, customized site lists, URL cache categorization and tagging capabilities.

The ACR^TM examines every page request to ensure its compliance with corporate, institutional, or parental acceptable use policies. The ACR^TM powerful set of algorithms analyzes and categorizes data in real-time. The database, the static URL lists, the URL tagging and URL cache categorization are complementary filtering layers guaranteeing total coverage of the Internet.
