CST VerdictShort answer
Security teams operating on-premises or hybrid networks with packet capture requirements should adopt Arkime for PCAP indexing and retrospective threat hunting; the open-source model means zero licensing friction at scale, and the tool's ability to ingest and search months of network traffic at line rate beats commercial alternatives on cost-per-terabyte. Arkime excels in the Detect function of NIST CSF 2.0, particularly for forensic investigation after an incident surfaces. This is not suitable for organizations needing real-time alerting, automated response, or managed service support; you're running it yourself. 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.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
