Introduction

SonicWall Content Filtering Service (CFS) provides businesses, educational institutions, libraries, government agencies and public Internet hotspots with comprehensive protection against inappropriate web content. SonicWall CFS blocks inappropriate websites, eliminates liability and increases productivity in organizations large and small. SonicWall CFS uses a comprehensive database of millions of URLs, IP addresses and websites. Thanks to the powerful rating and caching architecture, website ratings are dynamically updated locally on the SonicWall Network Security Appliances and reconciled on the fly. With CFS, administrators can define access rules based on over 56 URL categories, user or group identities, or time of day.
