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.
With SonicWALL CFS, network administrators have a flexible tool to provide comprehensive filtering
based on keywords, time of day, trusted and forbidden domain designations, and file types such as
Cookies, Java™ and ActiveX® for privacy. SonicWALL CFS automatically updates the filters, making
maintenance substantially simpler and less time consuming.
SonicWALL CFS can also be customized to add or remove specific URLs from the blocked list and to
block specific keywords. When a user attempts to access a site that is blocked by the SonicWALL
security appliance, a customized message is displayed on the user’s screen. SonicWALL security
appliance can also be configured to log attempts to access sites on the SonicWALL Content Filtering
Service database, on a custom URL list, and on a keyword list to monitor Internet usage before
putting new usage restrictions in place.
• SonicWALL CFS Standard blocks 12 categories of objectionable, inappropriate or unproductive
Web content. SonicWALL CFS Standard runs on SonicOS Standard 2.0 (or higher).
