Full packet capture (FPC) is a valuable tool for investigating security breaches because it provides comprehensive data that can be used to reconstruct the event and identify the root cause. By capturing every packet, FPC allows engineers to see exactly what took place during the breach, including the TCP flags set within each packet, which can help focus on suspicious packets to identify malicious activity. It also collects metadata, including IP traffic packet data that is sorted, parsed, and indexed, and provides the full TCP streams to follow the metadata to identify the incoming threat
