Content Filtering Client 3.1 Getting Started Guide

Overview

SonicWall™ offers comprehensive web content security that blocks selected web content and enforces protection and productivity policies. The main components are Content Filtering Service (CFS), SonicWall Content Filtering Client (CFC), and EPRS (Enforced Policy & Reporting System). CFS runs on the firewall and protects the devices behind the firewall. Content Filtering Client runs on the client devices—like a laptop, for example—and protects devices regardless of where the device is located, even if it is connected outside the firewall. EPRS provides administrators with the means to manage Content Filtering Client from a central web interface.

Content Filtering Client Overview

The SonicWall Content Filtering Client (CFC) provides protection and productivity policy enforcement for businesses, schools, libraries and government agencies. Content Filtering Client has a revolutionary content filtering architecture that utilizes a scalable, dynamic database to block objectionable and unproductive Web content.

Content Filtering Client combines control and flexibility to ensure protection and productivity. It prevents individual users from accessing inappropriate content while reducing organizational liability and increasing productivity. Web sites are rated according to the type of content they contain. Content Filtering Client filters access to these web sites based upon their ratings and based on the policy settings for that user or group.

Businesses can typically control web surfing behavior and web content when the browsing is initiated on a device within the perimeter of the network security appliance by setting filter policies on the appliance. But when the same device, a laptop for example, exits the perimeter, the control is lost. The Content Filtering Client addresses this gap by blocking objectionable and unproductive web content outside the network security appliance perimeter.

SonicWall network security appliances work in conjunction with SonicWall Content Filtering Client automatically. The client is designed to work with Windows, Mac OS and Chrome devices.

The three main functions of the SonicWall Content Filtering Client solution are:

 

Network security appliance running SonicOS
