Content Filtering Service Premium Edition
SonicWall™ Content Filtering Service (CFS) helps organizations such as educational institutions, businesses and government agencies to enforce their protection and productivity policies and block inappropriate, unproductive and even illegal web content. Featuring a dynamic rating and caching architecture, SonicWall CFS provides granular tools to create and apply web use policies that allow or deny students, employees and other end users access to websites that contain objectionable web content, providing the ideal combination of control and flexibility to ensure the highest levels of protection and productivity. Data can be sent to the SonicWall Analyzer traffic analytics and reporting package for a deeper level of web usage visibility through graphs, charts and data search functionalities. And as an added benefit, SonicWall Content Filtering Service is configured and managed directly on the firewall, eliminating the need for a costly, dedicated filtering server.
Protection and compliance for schools and libraries
Educational institutions have a responsibility to protect students from inappropriate and harmful web-based content when they provide internet access in the classroom. And in order to receive eRate funding, schools and libraries are required to install a content filtering solution in compliance with the Children's Internet Protection Act (CIPA). SonicWall CFS offers the flexibility to set custom policies for students and teachers by time of day, making it ideal for educational settings. Furthermore, the reporting necessary to comply with CIPA mandates can be fulfilled by SonicWall's Global Management System (GMS) and Analyzer reporting package.
In addition to external regulation compliance, CFS is an integral part of internal compliance programs designed to reduce the liabilities that may incur when inappropriate content is allowed into the network. When web access is unrestricted, not only is the result counter-productive, it can also result in costly lawsuits.
Productivity and security for businessesFor businesses and government agencies, providing employees with uncontrolled web access can result in non-productive web surfing, creating tremendous losses in productivity, not to mention the potential for legal liability. Unrestricted access can also lead to infection by viruses, Trojans, adware and other malware because many of the sites included in blocked categories are common sources of malicious attacks. SonicWall CFS helps reduce these risks by enabling organizations to restrict access to websites containing unproductive or dangerous content.
An easy to manage solutionSonicWall CFS combines application-based policy enforcement with comprehensive content filtering for a cost-effective, easy-to-manage solution. URLs, IP addresses and domain ratings are cached locally on the firewall, reducing response time to frequently visited sites to a fraction of a second. Administrators can control bandwidth based upon Content Filtering Service rating, as well as specific IP address, site or even application, when the solution is combined with SonicWall Application Intelligence and Control.
Flexibility and policy enforcementAdministrators are free to create local or enterprise-wide policies that are specifically designed to meet their own internal requirements as well as legislative mandates. The dynamic rating architecture can be used to block over 56 categories of objectionable or unproductive web content, providing a high level of transparent control, ease of administration and granular policy enforcement. The local URL filtering feature adds flexibility by letting administrators go beyond categories to create custom block and allow lists for specific domains or hosts. Policies can be applied to individuals or defined groups (e.g. students and faculty) and set to block automatically downloadable files or apply filtering by time of day.
Caching and performanceSonicWall CFS is built on a high-performance web rating and caching architecture that allows administrators to block sites automatically by category for easier administration. The caching feature stores URL ratings locally on the SonicWall firewall, reducing response times to a fraction of a second. In addition to filtering inappropriate web content, CFS enhances performance by filtering out download sites for MP3s, streaming media, freeware and other files that consume tremendous amounts of bandwidth and are often the source of spyware and other malware.
Visibility and reportingDeploying SonicWall Analyzer reporting software with SonicWall CFS enables organizations to run granular reports summarizing web activity details. The joint solution allows companies to easily create and deliver customized real-time and historical reports in a variety of formats and also gain fast insights through “at-a-glance" reporting capabilities.
How It Works
SonicWall CFS is based on a rating architecture that relies on a dynamic database to block objectionable or inappropriate websites. CFS cross-references all websites as they are requested against a vast and highly accurate database of URLs, IP addresses and domains. The SonicWall firewall then receives a rating in real time, and compares that rating to the local policy setting. The appliance will then either allow or deny the request, based on locally configured policy.
SonicWall CFS has categorized over 20 million URLs, IP addresses and domains in a continuously updated, dynamically rated database, with thousands more added daily. Because the ratings are determined both by artificial intelligence and human observation, the database is highly accurate and the instance of false positives is minimized. The policy-based system allows the administrator to block all pre-defined categories or any combination of categories, and to apply these policies on a granular level. For example, if one group of users requires access to sites typically found within one category, this level of access can be granted while still denying access to other users.
Categories range from offensive types of content such as "Violence," which would include anti-social websites that advocate use of weapons or explosives, to sites that may not be offensive but would otherwise cause a potential risk to the network in terms of bandwidth usage, such as "Freeware/Software downloads" or "Multimedia."
