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.
Mid-market and enterprise security teams drowning in alert noise will appreciate Clear NDR's transparent detection logic; you see exactly why Suricata flagged something instead of trusting a black-box ML score. The platform covers DE.CM and DE.AE strongly across hybrid deployments, meaning detection and analysis work whether you're on-premise, cloud, or split. Skip this if your team lacks the network visibility to feed it properly or if you need incident response automation to move at wire speed; Clear NDR excels at reconstruction and evidence collection after the fact, not real-time blocking.
