To aid in endpoint detection and alert investigation, the Cortex XDR agent collects endpoint information when an alert is triggered.
When the Cortex XDR agent raises an alert on endpoint activity, a minimum set of metadata about the endpoint is sent to the server as described in Metadata Collected for Cortex XDR Agent Alerts.
When you enable behavioral threat protection or EDR data collection in your endpoint security policy, the Cortex XDR agent can also continuously monitor endpoint activity for malicious event chains identified by Palo Alto Networks. The endpoint data that the Cortex XDR agent collects when you enable these capabilities vary by platform type.
Note
Agents with Cortex XDR Pro per Endpoint apply limits and filters on network, file, and registry logs. To expand these limits and filters, the Extended Threat Hunting Data (XTH) add-on must be purchased.
The tables below note whether specific logs require the XTH add-on.
When the Cortex XDR agent raises an alert on endpoint activity, the following metadata is sent to the server:
Field | Description |
---|---|
Absolute Timestamp | Kernel system time |
Relative Timestamp | Uptime since the computer started |
Thread ID | ID of the originating thread |
Process ID | ID of the originating process |
Process Creation Time | Part of the process unique ID per boot session (PID + creation time) |
Sequence ID | Unique integer per boot session |
Primary User SID | Unique identifier of the user |
Impersonating User SID | Unique identifier of the impersonating user, if applicable |

In Traps 6.1.3 and later releases, Cortex XDR and Traps agents can send the following Windows Event Logs to the tenant.
Note
The XTH add-on is required for Windows event log collection.
