A Web filter is a program that can screen an incoming Web page to determine whether some or all of it should not be displayed to the user. The filter checks the origin or content of a Web page against a set of rules provided by the company or person who has installed the Web filter. A Web filter allows an enterprise or individual user to block out pages from Web sites that are likely to include objectionable advertising, pornographic content, spyware, viruses, and other objectionable content. Vendors of Web filters claim that their products will reduce recreational Internet surfing among employees and secure networks from Web-based threats.

Content Filtering (Information Filtering)

On the Internet, content filtering (also known as information filtering) is the use of a program to screen and exclude from access or availability Web pages or e-mail that is deemed objectionable. Some Web filter products also provide reporting so that the installer can see what kind of traffic is being filtered and who has requested it. Some products provide soft blocking (in which a warning page is sent to the user instead of the requested page while still allowing access to the page) and an override capability that allows an administrator to unlock a page. While a Web filter can screen out a certain amount of malware, security experts advise other forms of protection as well, such as the installation of desktop and network antivirus software. A Web filter is often installed as part of a proxy server and firewall.

What are the benefits of web content filtering?

Some of the most serious threats to any business are hacking, phishing, viruses, and malware. Phishing, for example, is when hackers steal sensitive information through deception, such as tricking employees into logging in to bogus firms in order to obtain login credentials. Without a doubt, the loss or corruption of sensitive data such as login credentials, personal information, accounting information, and legal papers may be disastrous for any business. As a result, content filtering measures are essential. Web content screening provides numerous advantages for both individual users and companies.
