Fing Security vs Kismet

Fing Security checks routers and networks for vulnerabilities, open ports, and threats. Scheduled router checks look for known vulnerabilities, outdated firmware, DNS hijacking risks, and exposed management interfaces. It can alert users when an unknown device joins and show that device's brand, model, and type. Fing also scans connected Wi-Fi networks for cameras and spy devices using a database of over 12 million known camera models. Fing Agent can run on Raspberry Pi, Docker, or NAS for ongoing automated checks. Home Assistant, IFTTT, and the Fing Local API support presence data, network events, and custom automation. The maker identifies IT consultants, MSPs, and small businesses as users for client audits and security monitoring. The free plan allows up to three scans per day; scheduled vulnerability scans and continuous threat detection require a subscription. Premium costs $7.99 per month and Professional costs $16.99 per month. Fing Desktop is available for Windows and macOS, but not currently Linux. Fing says it is SOC 2 Type II certified.

Kismet is a free, open-source wireless sniffer, intrusion detection system, wardriving tool, and packet capture tool. Depending on hardware and driver support, it can capture Wi-Fi, Bluetooth, Bluetooth LE, Zigbee, wireless sensor, airplane beacon, and power meter data. It runs headless as a standalone capture and wireless intrusion detection system, or with a web interface. Linux and macOS are supported directly; Windows use is through WSL. Remote capture forwards capture types over TCP sockets or websockets for centralized collection. Kismet’s kismetdb logfile combines packets, device records, location, and runtime data in an SQLite3-based file. A REST-like API offers JSON records, streaming pcap-ng, and websocket publish-subscribe endpoints. WIDS alerts can be connected through REST APIs, syslog, and some SIEM tools. The project says stationary use is most effective for WIDS; mobile or channel-hopping operation can reduce accuracy and coverage. Its macOS adapter support is limited, and WSL cannot access local hardware interfaces for packet capture, though remote capture is supported. The downloads page lists 2025-09-R1 as the latest stable release.
