CST VerdictBased on our analysis of available product data, here is our conclusion:
Incident response teams who need to pivot quickly from packet captures to threat hunting will find fatt indispensable; it extracts JA3 and HASSH fingerprints that let you correlate C2 signatures across your full traffic history in minutes instead of hours. Free and 679 GitHub stars means it's already baked into most mature IR playbooks, lowering your team's time-to-triage on network-based indicators. Skip this if you're looking for packet analysis beyond metadata extraction or need a GUI; fatt is CLI-only and does one job well, which is exactly why it works.
Forensic analysts and incident responders who need to surgically edit pcap files during investigations will find Netdude invaluable; it's the only free framework that lets you modify and replay network dumps without rebuilding captures from scratch. The tool has been stable across tcpdump formats since the early 2000s, making it reliable for reconstructing traffic patterns during containment and evidence collection. Skip this if your team primarily needs real-time packet capture or visualization; Netdude is post-incident triage, not live monitoring.
