SonicWALL Content Filtering Service
SonicWALL Content Filtering Service (CFS) enforces protection and productivity policies for
businesses, schools and libraries to reduce legal and privacy risks while minimizing administration
overhead. SonicWALL CFS utilizes a dynamic database of millions of URLs, IP addresses and
domains to block objectionable, inappropriate or unproductive Web content. At the core of
SonicWALL CFS is an innovative rating architecture that cross references all Web sites against the
database at worldwide SonicWALL co-location facilities. A rating is returned to the SonicWALL
security appliance and then compared to the content filtering policy established by the administrator.
Almost instantaneously, the Web site request is either allowed through or a Web page is generated by
the SonicWALL security appliance informing the user that the site has been blocked according to
policy.

Cookies, Java™ and ActiveX® for privacy. SonicWALL CFS automatically updates the filters, making
maintenance substantially simpler and less time consuming.
