URL Filtering is a blade that enables administrators to control access to millions of websites by category, users, groups, and machines. URL Filtering can be used to improve organizational security, decrease legal liability, and control data security by preventing users from accessing malicious or inappropriate websites. However, URL Filtering cannot be used to control bandwidth issues, such as limiting the amount of traffic or prioritizing certain applications over others3. For that purpose, other blades such as QoS (Quality of Service) or SecureXL are more suitable. References: Check Point R81 URL Filtering Administration Guide
