NetTwinGuard

NetTwinGuard is a web app (with an optional lightweight on-prem sensor) that builds a living inventory of IoT devices by passively observing network traffic, then flags risky changes: new devices, firmware shifts, unusual DNS destinations, lateral movement attempts, and insecure protocols. It generates a “network twin” baseline per site and alerts only on meaningful deviations to reduce noise. The product focuses on small-to-mid businesses that can’t afford a full SOC or complex NAC rollout. Setup is realistic: install a sensor on a mirrored switch port or gateway, connect to the cloud console, and start seeing device identities and behavior within hours. Reports are built for non-experts: what changed, why it matters, and the minimum action (isolate VLAN, block domain, disable UPnP, rotate credentials). It’s not magic—encrypted traffic limits visibility—but it still catches most operational IoT risks.
