SonicWall Content Filtering Client service provides protection and productivity policy enforcement for businesses, schools, libraries and government agencies. Organizations can use filtering policies on their gateway firewall to control web surfing behavior and content when the browsing is initiated within the perimeter of the firewall. But when the same client device exits the perimeter, the control is lost. The SonicWall Content Filtering Client service addresses this gap by blocking objectionable and unproductive web content even when the client machine is outside the firewall perimeter. SonicWall firewalls working in conjunction with SonicWall Content Filtering Client ensure that all client machines have the latest software updates for filtering web content accessed from any location. The client is designed to work with both Windows and Mac OS.
