Web Filtering

The abundance of harmful information on the Internet is posing a serious challenge for employers and parents alike - How can I regulate what my employee/child does on the net? The USR8200 Firewall/VPN/NAS's Web-filtering allows parents and employers to regulate, control, and monitor Internet access. By classifying and categorizing online content, it is possible to create numerous Internet access policies, and easily apply them to your home network computers. As a result, you may keep your children from harm's way by limiting access to adult and violent material, or increase employee productivity by regulating access to non work-related Internet content.



To effectively filter web content one must first have a good idea of the kind of information that is available on the Internet. It is necessary to formulate a landscape of the accessible content, categorize and classify themes and subjects that may be considered inappropriate.

The USR8200 Firewall/VPN/NAS's Web-filtering categorization methodology provides an easy and straightforward method for fine-grained content filtering. The web-filtering module is constantly updated with URL-based information classified according to the following categories:

  • Child protection
  • Recreation and Entertainment
  • Personal business
  • Bandwidth control
  • Advertisements
  • Chat
  • Remote Proxies and Hosting Sites (Possibly untrusted sources)
  • Other

Each category can be expanded into subcategories for better content control. For instance, the Recreation and Entertainment category is comprised of subcategories such as:

  • Arts and Entertainment
  • Education
  • Games
  • Hobbies and Recreation
