What is a Web Filter?

A Web filter is an application that screens incoming Web pages. This application verifies web pages that should be accessed by certain users. This application compares all incoming web pages against the certain information technology rules and regulations stipulated by the installer.

Sometimes these filters over block or under block, which can result in the users not finding some information, based on constant rules hence blocking a wrong site. On the other hand, filters do not guarantee that they will block all the unsuitable content either.

Most schools, businesses or companies use an Internet censorship service. By using their Content-control software that is designed to restrict or control the content a user of the school or company is blocked from some internet access. This software normally used to restrict materials that are delivered over the Internet via the Web, e-mail, or other means. Content-control software normally determines what content will be available and what content will be blocked. The motive for the censorship is normally to prevent access to content, which the computer's owners and other authorities may consider intolerable.
