SyntheticProcessRollup2 provides process data similar to ProcessRollup2, but it is generated for a process that was already running before the Falcon sensor started observing the host. A common example is a long- lived operating-system process that began before sensor installation or before the sensor service started.
Because Falcon did not witness the original process-creation moment, it creates synthetic process telemetry so the process can still be represented and related to later activity. The event is not created by an analyst, OverWatch, or Charlotte AI, and it is not a fusion of human-added context. Its purpose is to preserve process visibility when the process predates sensor observation. Therefore, option D accurately describes when SyntheticProcessRollup2 is found.
