Techopedia Explains Website Filter

A website filter is a common browser and host-based security hardening feature implemented in a network firewall or proxy server to ensure the safety of an organization’s digital assets. Website filters block incoming traffic from unsafe zones, particularly those with malicious intent. Once configured, a website filter only allows traffic designated as safe by the the administrator. All other traffic is prevented from network/host entry.

Besides default unsafe traffic blocking, website filters also may be configured to block safe yet inappropriate website usage, especially in organizations seeking to curb non-productive Internet use via social media websites, instant messenger applications, and other non-business applications.
