What is a Web Filter?

Web filter is a software that screens the web pages and determines if the page should be displayed to the user or not, based on the permission configured by IT admins. This feature is used to create a fortified boundary that protects IT admins' networks from unexpected attacks that arise from landing on malware-infected websites, download of malicious files and also to block access to unnecessary distractions that keep users away from work.
