What is the function of WebFilter in the context of URL categorization?

The function of WebFilter in the context of URL categorization is to categorize web traffic based on predefined policies. This involves analyzing the URLs that users attempt to access and determining their categories, such as business, entertainment, or potentially harmful content, based on a set of rules or a database that contains categorized websites.

By categorizing URLs, the WebFilter allows organizations to enforce appropriate browsing policies, enabling them to permit or restrict access to various types of content according to their needs. This provides the capability to ensure compliance with corporate policies and to enhance user safety by blocking access to malicious or inappropriate sites.

This feature is essential in a network security context, as it helps maintain an organization's security posture and reduces the risk of malware infections and data breaches by controlling access to known sites associated with risk. The other functions identified do not specifically pertain to the URL categorization process facilitated by WebFilter.
