CST VerdictBased on our analysis of available product data, here is our conclusion:
Security engineers and incident responders who code in Clojure will find clj-net-pcap invaluable for custom packet analysis workflows that off-the-shelf tools can't handle; it wraps jNetPcap to give you raw pcap access without leaving your JVM environment. The 68 GitHub stars and active maintenance reflect a tool favored by practitioners building domain-specific forensics pipelines rather than general-purpose capture suites. Skip this if your team needs GUI-driven packet inspection or lacks Clojure expertise; this is a developer tool, not a point-and-click alternative to Wireshark.
Windows incident responders and threat hunters working inside corporate networks will get the most from Fibratus because it gives raw kernel-level visibility into process behavior without the licensing cost of commercial EDR. It's free and open-source with 2,373 GitHub stars, which means you're getting tested code plus a community that actually uses it for real investigations. Skip this if you need cross-platform coverage or graphical case management; Fibratus is Windows-only and command-line driven, built for practitioners who think in system calls, not dashboards.
