Fing has become the essential network security tool for smart home owners. Our 2026 review evaluates both the free Fing app and premium Fingbox hardware. The free Fing app discovered all 28 connected devices on our network within 45 seconds. Each device was identified by name, manufacturer, IP and MAC address. The network security check identified 5 open ports, 2 devices with outdated firmware, and one device communicating with a known malicious IP. The Wi-Fi analyzer helped us reduce interference and improve throughput by 18%. Fing Premium adds automated device alerts, internet speed testing, and digital presence detection. Fingbox adds Wired/Wireless Network Watchdog and blocked device alerts. Together, Fing and Fingbox provide unparalleled visibility into your home network.
