CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams responsible for wireless security posture will find MeerCAT-Pro's strength in asset discovery and location tracking; the GIS-based visualization turns wireless inventory from a spreadsheet problem into something you can actually act on across multiple sites. On-premises deployment and native integrations with Kismet and Wireshark mean it fits cleanly into existing detection workflows without forcing new tooling. Skip this if your wireless footprint is minimal or if you need detection-to-response automation; MeerCAT-Pro prioritizes the Identify and Detect phases of NIST CSF but leaves the incident response half to you.
Network engineers and threat hunters who need to inspect live traffic or troubleshoot connectivity issues should reach for Wireshark; it's the only tool that gives you packet-level visibility into exactly what's crossing your wire, without licensing costs or vendor lock-in. Deployed across virtually every enterprise network since 1998, Wireshark captures and decodes 900+ protocols natively, making it invaluable for NIST Detect work when you need to see what IDS alerts actually mean. Skip this if your team expects guided investigation or automated threat correlation; Wireshark requires expertise to read its output and won't tell you what to do with the packets you find.
