The Dell SonicWALL Content Filtering Service (CFS) provides the tools to create and enforce protection and productivity policies while blocking access to websites containing inappropriate and unproductive content. Ideal for schools, businesses, libraries, and government agencies, CFS runs on Dell SonicWALL firewalls to minimize administration overhead and reduce legal and privacy risks. Network administrators can use CFS to create and apply policies that allow or deny access to sites based on individual or group identity, or by time of day, for over 56 predefined categories. They can also customize CFS to block or unblock URLs and specific keywords.
