(SoftPerfect WiFi Guard)是局域网内的守护神，名称虽然有个Wifi，不过实体的有线网路一样可以使用，能侦测区域网路内的所有连线设备，陌生的设备将会亮红灯，而认识的装备是亮绿灯，一段时间后会自动的重新扫瞄，若是有陌生设备则会发出通知，对网管来说也是实用的侦测工具。
SoftPerfect WiFi Guard is an essential tool for everyone running a small wireless network and striving to keep it safe and secure. Generally, modern Wi-Fi networks are well protected, but there are a number of weaknesses that can compromise your Wi-Fi password; this includes vulnerabilities in encryption and brute force attacks. As a result, someone can gain unauthorised access to your Internet connection and LAN and exploit them while staying unnoticed.
Perhaps, you can say: “No big deal, I have unlimited Internet traffic!”, but what about someone reading your personal emails, stealing private information or breaking the law online while using your Internet connection?
Here comes our little application: it will alert you if your network is used without your knowledge. WiFi Guard is a specialised network scanner that runs through your network at set intervals and reports immediately if it has found any new, unknown or unrecognised connected devices that could possibly belong to an intruder.
Pings computers and other network devices and displays those alive.
Detects firewalled computers that do not respond to ping.
Scans your network at a specified interval.
Immediately alerts you if an unknown device is found.
