Arkime vs BZAR: 2026 Comparison
Arkime is a free network detection and response tool. BZAR is a free network detection and response tool. Compare features, ratings, integrations, and community reviews side by side to find the best network detection and response fit for your security stack.
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 already running Zeek will find BZAR's value in its ATT&CK-aligned detection logic without the licensing cost of commercial NDR platforms. The 622 GitHub stars and free deployment model mean you're getting detection tuning from practitioners who've actually hunted in Zeek logs. BZAR prioritizes detection over response; you'll need a separate workflow to act on the notices it raises, so it's a poor fit for teams expecting their NDR tool to handle investigation and containment.
