Infoblox Threat Intelligence Data Exchange (TIDE) leverages highly accurate machine-readable threat intelligence (MRTI) data to aggregate and selectively distribute data across a broad range of security infrastructure.

Palo Alto Firewalls can leverage Infoblox's threat intelligence and block access to malicious destinations by domain names, IP addresses and URLs. 

The attached guide provides you step by step instruction how to load BloxOne Threat Defense IOCs on Palo Alto firewalls, meanwhile the guide assumes that you already have experience with BloxOne Threat Defense TIDE REST API and doesn't cover how to retrieve indicators from BloxOne Threat Defense TIDE.

Please keep in mind that Palo Alto firewalls support limited quantity indicators. Please refer PAN-OS Administrator's guide for details.
