Cortex Data Lake is Palo Alto Networks’ cloud-based
logging infrastructure. Before you can configure your managed firewalls
to send logs to Cortex Data Lake (previously called the Logging
Service), you need to purchase a license for the volume of logs
in your deployment, and install the cloud services plugin. If you
already have on premise Log Collectors, you can use Cortex Data
Lake to complement and augment your existing setup.
