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.
Forensic analysts and incident responders who need to parse Windows NT artifacts during post-breach investigations will find libfwnt essential for automating access to registry hives, file systems, and event logs without building custom parsers. The library's direct implementation of Windows data structures means you're reading native formats rather than relying on third-party interpretations, reducing the risk of missing evidence due to parsing gaps. Skip this if your team uses commercial DFIR platforms that bundle these functions; libfwnt demands development resources to integrate, making it best suited for shops with in-house coding capability or those building custom forensic toolchains.
