Kismet vs MeerCAT-Pro: 2026 Comparison
Kismet is a free intrusion detection and prevention systems tool. MeerCAT-Pro is a commercial intrusion detection and prevention systems tool by Secure Decisions. Compare features, ratings, integrations, and community reviews side by side to find the best intrusion detection and prevention systems fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Wireless security teams operating in environments where rogue access points and unauthorized clients pose immediate risk should deploy Kismet; its packet capture and real-time network mapping catch what perimeter tools miss. The tool has 2,072 GitHub stars and runs freely on Linux, making it ideal for resource-constrained teams that can't justify commercial wireless IDS licensing. Kismet prioritizes detection over prevention, so organizations needing automated response or integration with existing SIEM stacks will find it limited; it's best suited to teams comfortable with manual threat investigation workflows.
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.
