URL Filtering Overview

The Palo Alto Networks URL filtering solution compliments App-ID by enabling 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 millions of websites that have been categorized into approximately 60-80 categories. You can use these URL categories as a match criteria in policies (Captive Portal, Decryption, Security, and QoS) or attach them as URL filtering profiles in security policy, to safely enable web access and control the traffic that traverses your network.
Although the Palo Alto Networks URL filtering solution supports both BrightCloud and PAN-DB, only the PAN-DB URL filtering solution allows you to choose between the
PAN-DB Public Cloud
and the
PAN-DB Private Cloud
. Use the public cloud solution if the Palo Alto Networks next-generation firewalls on your network can directly access the Internet. If the network security requirements in your enterprise prohibit the firewalls from directly accessing the Internet, you can deploy a PAN-DB private cloud on one or more M-500 appliances that function as PAN-DB servers within your network.
