Content & URL Filtering

Content & URL Filtering

Content filtering usually works by specifying character strings that, if matched, indicate undesirable content that is to be screened out. Content is typically screened for pornographic content and sometimes also for violence- or hate-oriented content. Critics of content filtering programs point out that it is not difficult to unintentionally exclude desirable content.

Content filtering and the products that offer this service can be divided into Web filtering, the screening of Web sites or pages, and e-mail filtering, the screening of e-mail for spam or other objectionable content.

URL filtering technology helps organizations to prevent computer users from viewing inappropriate web sites or content, or to prevent access of known malware hosts.

The filter checks the origin or content of a Web page against a set of rules provided by company or person who has installed the URL filter. An URL filtering solution can be installed as a standalone solution, on a firewall or on a proxy server.
