CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security engineers validating detection rules or stress-testing incident response workflows should reach for tcpreplay because it replays real network traffic at scale without needing production data or live systems. The tool ships with packet editing capabilities that let you mutate captured traffic on the fly, letting you simulate specific attack patterns or edge cases your monitoring stack might miss. Skip this if your team needs GUI-driven traffic generation or wants pre-built attack scenario libraries; tcpreplay is command-line only and requires you to already have pcap files or the knowledge to craft them from scratch.
