Levels of Categorization

When adding a policy and determining which categories of content to block, there are several levels of categorization to choose from: High, Moderate, Low, and Custom. Categories included in the High, Moderate, and Low levels are predetermined and cannot be changed. Custom includes all levels—High, Moderate, and Low—as well as categories unique to Custom. With Custom, you can select categories and create your own custom list of categories to block.   


High, Moderate, and Low Category Levels

High—Blocks adult-related status, illegal activity, social networking, video sharing site, and general time-wasters. Includes all Moderate and Low content categories.
