CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams investigating application performance issues tied to network behavior will find Justniffer's TCP/IP flow reconstruction more precise than packet sniffers that stop at layer 4, especially for tracking response times across complex request chains. It's free and requires no agents, so you can deploy it immediately on any Linux system without procurement friction. Skip this if you need threat hunting or anomaly detection; Justniffer is a passive analyzer, not a detection engine, and gives you visibility into what happened, not what's attacking you.
Security teams building custom network detection pipelines on Linux will find OVIZART's protocol dissection engine valuable because you can fork and modify the detection logic directly without vendor lock-in, something closed NDR platforms won't let you do. The Django foundation means you're not fighting a black-box appliance; you can integrate custom parsers for proprietary protocols or legacy traffic patterns in hours instead of months. Skip this if your team lacks Python developers or needs vendor-backed SLA guarantees and threat intelligence feeds; at 49 GitHub stars, you're maintaining this yourself.
