CST Verdict

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

tcptraceroute

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.
