URL Filtering provides policy-based control of websites by using the information contained in URLs. This feature helps network administrators monitor and control user access to malicious websites on mobile networks.
As an administrator, you can configure a URL filtering policy by using either the URL Categorization feature or the URL List feature.
URL List. Controls access to blacklisted websites and web pages by denying access to URLs that are in a URL set imported into the appliance.
URL Categorization. Controls access to websites and web pages by filtering traffic on the basis of a predefined list of categories.
