BZAR is a free network detection and response tool. Gatewatcher Plateforme NDR is a commercial network detection and response tool by Gatewatcher. Compare features, ratings, integrations, and community reviews side by side to find the best network detection and response fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Mid-market and enterprise security teams defending hybrid IT/OT networks need Gatewatcher Plateforme NDR because it actually sees what's moving on your wires without forcing you to choose between network visibility and threat response. The platform covers all six critical NIST Detect and Respond functions, from asset discovery through incident orchestration, and its optical and copper TAP-based capture means you're not relying on agent coverage to find lateral movement. Skip this if your environment is purely cloud-native or if you need a point tool rather than the operational overhead of a full NDR platform; Gatewatcher prioritizes detection depth over ease of deployment.
