What NetAlertX actually does
NetAlertX is a network utility designed to scan local networks for connected hardware and flag any unknown devices. It acts as an automated presence detector and intruder alert system for self-hosted environments. The project is distributed under the GPL-3.0 licence.
Best fit: Home lab operators and system administrators who want an automated way to monitor local network attachments and spot unauthorised clients.
Worth knowing: You will need to ensure your scanning configuration aligns with your local subnet layout to avoid false positives or missed devices, which can require ongoing tuning.
Deployment notes
As a containerised application, you will typically need to configure persistent storage for historical scan logs and ensure the container has appropriate network access permissions to scan your subnet.
