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.
Incident response teams with limited budgets who need to extract files from pcap files during investigations should reach for pcapfex, a free tool that does one job without bloat. It's actively maintained on GitHub with 222 stars and requires no licensing overhead or integration complexity. Skip it if your team expects a GUI or needs to automate file extraction at scale; pcapfex is CLI-driven and built for analysts who prefer command-line forensics workflows.
