The use of a web filter can allow a company or organization to determine specific areas of the Internet that can or cannot be accessed by users. These can take the form of web content filters, or specific web page filters. Controlling access by means of filters can go a long way towards curtailing unwanted Internet usage.

What Is a Web Filter?

A web filter is a means by which an employer or other type of institution can set up criteria for accessing the Internet. This can take the form of certain keywords contained within website URLs that the filtering software knows to block allow access. This could also mean not allowing certain file types to be downloaded. Filtering web access allows a company or organization to give users access to the Internet, but also helps to keep them away from the type of material they should not be accessing.

Filtering in Educational Environments

Schools that use the Internet for educational purposes also need to be careful about what kinds of sites students are allowed to access. As with businesses, being able to filter the type of Internet access that is being conducted is important. Students can be given limited access to the Internet through the filtering of any given criteria the user wants.

Of course, no web filtration system is completely foolproof. Innovative website designers nowadays are always trying to find clever ways to trick users into visiting their sites, with misleading keywords, or unknown file types. Even so, the use of web filtration technology can at least help in protecting an organization from most unwanted Internet access.
