Hi @hbshin ,


The categorization is done either by IP address or via the Common Name from the SSL certificate or Server Name Indication (SNI).

Hi @hbshin ,


How PAN-DB works


The PAN-DB Core, located in the Palo Alto Networks threat intelligence cloud, has a full URL and IP database to cover web security needs.

Millions of URLs and IPs are classified in a variety of ways. In addition to the “Multi-language classification engine” and the “URL change request from users,” PAN-DB receives malicious URL and IP information from WildFire.


Cheers !
