CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, 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.
