CST VerdictBased on our analysis of available product data, 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.
Security teams running smaller networks or lab environments who need free, lightweight malicious traffic detection will find Maltrail useful for its low overhead and dual approach using blacklist matching and behavioral heuristics. The 7,182 GitHub stars and active community indicate reliable detection logic without licensing friction. Skip this if you need managed threat hunting, alert tuning at scale, or integration with your existing SIEM; Maltrail is a detection engine that requires manual investigation and assumes your team has bandwidth to operationalize raw findings.
