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.
Network engineers and incident responders who need to map routing paths through restrictive firewalls should use tcptraceroute; it exploits TCP traffic that firewalls typically allow, bypassing the UDP and ICMP blocks that stop standard traceroute. The tool is free and runs on Linux, BSD, and macOS, making it trivial to deploy across your existing infrastructure without licensing friction. Skip this if your team relies on GUI-based network mapping tools or needs real-time graphical dashboards; tcptraceroute is command-line only and shows you the path, nothing more.
