NetAlert is designed to provide intruder detection for the home and office - watchdog program that sits in your system tray monitoring your IP ports.
NetAlert displays a visual and/or audible alert when it detects a connection and resolves the IP Address of the remote system, via a domain name server, whether you are on the Internet or on a Corporate Network. If you are using NetAlert 2001 to monitor a remote server, it can even send you an email notification when an intruder is detected.
