When an administrator has numerous firewalls and Panorama, WildFire logs need to be forwarded from the firewalls to Panorama in order for them to be visible in Panorama. WildFire logs contain information about malicious files that have been detected by WildFire and provide detailed information such as the file's hash value, severity, and other attributes. This information can then be used to help identify threats and take appropriate security measures. Proper configuration of forwarding WildFire logs is essential for monitoring malicious activity and ensuring the security of the network.

The Device Telemetry data is stored on Cortex Data Lake3, which is a cloud-based service that collects and stores logs from your firewalls and other sources. Cortex Data Lake also enables you to analyze and visualize your data using various applications.
To use Device Telemetry, you need to install a device certificate on your firewall3. This certificate authenticates your firewall to Cortex Data Lake and encrypts the data in transit.
