Palo Alto Networks URL Filtering protects against web-based
threats by giving you a way to safely enable web access while controlling
how your users interact with online content.
With URL Filtering enabled, all web traffic (HTTP and HTTPS)
on any port is compared against the URL filtering database, which
contains a listing of millions of websites that have been categorized.
You can use these URL categories as a match criteria to enforce
security policy. You can also use URL filtering to enforce safe
search settings for your users and to Prevent
Credential Phishing based on URL category.
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
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.
