CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Forensic analysts and incident responders who need to surgically edit pcap files during investigations will find Netdude invaluable; it's the only free framework that lets you modify and replay network dumps without rebuilding captures from scratch. The tool has been stable across tcpdump formats since the early 2000s, making it reliable for reconstructing traffic patterns during containment and evidence collection. Skip this if your team primarily needs real-time packet capture or visualization; Netdude is post-incident triage, not live monitoring.
