IP & network
Your public IP, subnet and routing determine who can reach your connection and how it is addressed on the internet — the starting point for almost every other check on this site.

MQTT, Modbus, RDP, VNC and the other protocols your devices and legacy systems speak were mostly designed for trusted local networks, not the open internet — exposing one is a common way in for an attacker.
