CST VerdictBased on our analysis of available product data, here is our conclusion:
Linux infrastructure teams running high-throughput packet capture workloads will extract the most from PFQ v6.2 because its in-kernel processing model eliminates the user-space bottleneck that commodity tools like tcpdump hit under load. The 523 GitHub stars and active Linux kernel integration speak to adoption among teams that actually process millions of packets per second, not theoretical capacity. Skip this if your team needs GUI dashboards or vendor-backed threat intelligence; PFQ v6.2 is a framework for engineers comfortable reading C code and tuning kernel parameters, not a point-and-click NDR appliance.
Linux-focused security teams managing sprawling microservices environments should skip this tool. Socket Sentry is a KDE Plasma 4 widget with 4 GitHub stars that displays real-time traffic for active network connections on individual Linux boxes, not a network detection and response platform. It's a desktop monitoring gadget from a decade-old desktop environment, not a deployable security product for teams running threat hunts or incident response at scale.
