CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:

CSPi Myricom nVoy Series AIR

Enterprise and mid-market IR teams investigating breaches need the nVoy Series AIR to turn alert noise into forensic evidence; it automatically matches your firewall and IDS alerts to actual network traffic, then pulls the full conversation files on demand so you're not reconstructing timelines from logs. Continuous 24/7 capture at 10Gbps with real-time indexing means you can retrieve retroactive proof of compromise for assets you define as critical, covering NIST Detect and Respond functions equally well. Skip this if your team lacks dedicated forensic analysts or if you need detection tuning beyond ingesting alerts; nVoy assumes your alerts are mostly good and focuses on proving what actually happened on the wire.

TCPFLOW

Forensics teams and incident responders who need to reconstruct network conversations during investigations should reach for TCPFLOW for its ability to reassemble TCP streams into readable payloads without the overhead of full packet capture tools. At 1,745 GitHub stars and free deployment, it's lightweight enough to run on resource-constrained endpoints or jump boxes where heavier PCAP analysis platforms won't fit. Skip this if your mandate is real-time threat hunting or continuous network monitoring; TCPFLOW is a surgical instrument for post-incident analysis, not a perimeter sensor.
