CFS Overview
SonicWALL Content Filtering Services Premium (CFS Premium) enforces protection and
productivity policies for businesses, schools and libraries to reduce legal and privacy risks while
minimizing administration overhead. CFS Premium provides network administrators with greater
control by automatically and transparently enforcing acceptable use policies.
SonicWALL CFS Premium gives administrators the flexibility to enforce content filtering on Zones
as well as custom content filtering policies for groups of users on the network. For example, a
school can create one policy for teachers and another for students.
How Does CFS Premium Work?
SonicWALL CFS Premium utilizes a dynamic database of millions of URLs, IP addresses and
domains to block 56 categories of objectionable, inappropriate or unproductive Web content. At the
core of CFS Premium 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.
Benefits
With SonicWALL CFS Premium, 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. CFS Premium
automatically updates the filters, making maintenance substantially simpler and less time
consuming.
SonicWALL CFS Premium 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 appliances 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.
