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.
Linux infrastructure teams doing packet-level forensics or protocol development will get the most from netsniff-ng toolkit because its zero-copy architecture captures full payloads at line rate without dropping frames under load. The toolkit ships with specialized tools like mausezahn for packet crafting and trafgen for traffic generation, which most commercial sniffers charge extra for or omit entirely. Skip this if your team needs GUI-based workflow, cross-platform support, or vendor backing; netsniff-ng is command-line only, Linux-exclusive, and maintained by a small community that won't answer your 3 a.m. page.
