The Palo Alto Networks URL filtering solution enables you to configure the firewall to identify and control access to web (HTTP and HTTPS) traffic and to protect your network from attack. With URL filtering enabled, all web traffic is compared against the URL filtering database, which contains a listing of websites, that have been categorized. You can use these URL categories as a match criteria in policies or attach them as URL filtering profiles in security policy, to safely enable web access and control the traffic, that traverses your network.
