Internet filtering is used to block or restrict access to certain web pages or web applications. This is particularly beneficial to parents wanting to prevent their children from accessing pornography or other inappropriate sites. With millions of accessible web pages, how do parents know which are objectionable? That's where internet filtering programs come in. These programs not only evaluate and rate web page content but can also remove offensive materials from pages. Parents can also use them to inflict time limits, record chat sessions, block newsgroups and restrict download abilities.
Often internet filtering programs and the term "parental controls" are used interchangeably. This is incorrect; many businesses also use internet filters to restrict and monitor employee web behavior. While similar in principle to a parental control, the intent of a business internet filtering program is more to prevent security threats and optimize available bandwidth.
