Fing Agent Raspberry Pi Kit – An all-in-one Raspberry Pi 4-based network monitoring solution

Fing Agent Raspberry Pi 4 Kit, network monitoring

Fing has recently introduced the “Fing Agent Raspberry Pi Kit“, also called “Fing Agent plug-and-play Raspberry Pi 4 kit”, for its Fing Agent network monitoring system, which can be considered a follow-up to the earlier Fingbox hardware released in 2017. While Fingbox was a custom appliance based on Ubuntu Core, the new kit uses a Raspberry Pi, making it easier to set up and use in a home or small office network. The kit includes a Raspberry Pi 4 Model B (2GB) in an aluminium case, a 32GB microSD card with Fing Agent preinstalled, a USB-C power supply with adapters, and a Cat 5e Ethernet cable. Once connected to the router, it works with the Fing app, desktop, or web to monitor devices, track uptime and speed, detect intrusions, and send alerts about unusual activity. It also supports device blocking, presence detection, and diagnostics, such as port scans and vulnerability checks. Making it […]
