This event is logged for each Windows Filtering Platform provider present when the Base Filtering Engine starts as part of Windows boot up. The Windows Filtering Platform is a foundation component of Windows that provides an API and base filtering engine upon which other network filtering applications are built, including several Windows networking components and potentially third-party applications.

Auditing:     Rarely

Enable only when you need a full inventory of WFP providers loaded at boot — useful for forensic baseline comparison, detecting rogue or malicious third-party providers injected by malware, or validating that only expected software has registered as a WFP provider.


Volume:     Low

A standard Windows system has only 3–6 built-in providers. Even with third-party security software, total count per reboot is typically fewer than 15 events. Always bounded per boot — never a continuous stream.
