CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Enterprise security teams investigating advanced breaches need NikOS Everest for its packet-level forensics depth; most tools give you alerts, this one gives you the actual network conversation that proves what happened. Query response time improved 4X in version 5.1, and the platform maps cleanly to NIST DE.CM and DE.AE for detection and analysis, though it prioritizes forensic investigation over automated response actions. Mid-market buyers should verify their network capture and storage budget before committing; this is a specialist tool for organizations with the ops maturity to run on-premises packet infrastructure, not a replacement for broader network monitoring.
