 PAN‑OS is the software that runs all Palo Alto Networks next-generation firewalls. This integration will allow your SOC to leverage automation to block traffic to/from specific IP or URL as a response to Azure Sentinel incidents.
 
-**PAN-OS custom connector** includes [various actions](./PaloAltoCustomConnector#actions-supported-by-palo-alto-custom-connector) which allow you to create your own playbooks from scratch. In addition to the connector, there are 3 OOTB **playbooks templates** which leverage it so you can start automating Blocking of IPs an URLs with minimum configurations and effort. The OOTB scenarios are leveraging **address objects groups**, which are pre-configured to be refferenced to Security Policy rules. The playbooks will add IPs and URLs as address objects to these groups, so the policies will apply on them.
