CST Verdict

Based on our analysis of core features, here is our conclusion:

Justniffer

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.
