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 teams with constrained budgets and on-premises infrastructure will get the most from ManageEngine NetFlow Analyzer; its flow-based approach costs far less than packet capture tools while still catching lateral movement through MITRE ATT&CK-mapped anomaly detection. The one-minute granularity and support for six flow formats means you're not locked into Cisco gear, and the machine learning detection directly addresses the Detect function within NIST CSF 2.0. Skip this if you need deep application forensics or plan to migrate to cloud-only architecture; NetFlow loses fidelity at the application layer and the on-premises-only deployment makes hybrid environments awkward.
