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.
Security teams doing incident response and threat hunting need Stenographer for one reason: it captures full packets at line rate without dropping traffic, which means you actually have the forensic record when you need it. A 1,800-star GitHub project with active use in production environments shows it handles sustained high-volume capture on modest hardware. Skip this if your team expects a GUI, query language, or built-in analytics; Stenographer is a capture engine, not an analysis platform, and you'll need separate tools to make sense of the pcap output.
