URL filtering is a technology that allows you to control
your users’ web access and restrict their access to sites known
to host malware or other threats.
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, PAN-DB,
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-600 appliances that function as PAN-DB servers within your network.
