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. Security teams running hybrid cloud environments who need to catch active attackers mid-campaign will get the most from Vectra AI Detections. Its behavioral detection engine identifies lateral movement and command-and-control activity across AWS, Azure, and on-premises networks simultaneously, which signature-based tools routinely miss. The platform covers NIST Detect and Analyze functions thoroughly but deliberately skips response automation and playbook execution, so you'll still need a separate SOAR or manual procedures to act on findings. Skip this if your priority is consolidating tools; Vectra is detection-focused and doesn't replace your incident response platform.
