Upon the first launch of WiFi Guard you will either see the main window, or this configuration dialog if the application needs some additional information: If you have not already done so, download a copy of WiFi Guard. It is a specialised network scanner that runs through your network at set intervals and reports immediately if it has found any new connected devices that could possibly belong to an intruder. Here comes our little application that alerts you whenever your network may be used without your knowledge. You may think: “Who cares! I’ve got unlimited traffic.” But what if someone reading your personal emails, stealing private information or breaking the law online while using your Internet connection? As a result, someone can gain an unauthorised access to your Internet and LAN, exploit them and stay unnoticed. Generally, modern WiFi networks are well protected, but there is a number of weaknesses that can compromise your WiFi password this includes vulnerabilities in encryption and brute force attacks. Please note, the program is free for Windows and Linux, but the Mac version costs $9.99.SoftPerfect WiFi Guard is an essential tool for everyone running a small WiFi network and striving to keep it secure. It's also lightweight and entirely free (no adware concerns), so if you're interested then you can try the program without suffering any hassles, penalties or problems.
SoftPerfect Wifi Guard does provide a simple extra layer of protection, though. Plainly this is no substitute for proper wireless network security, such as using the highest levels of encryption supported by all your network devices. SoftPerfect Wifi Guard will scan your system every half hour, though, and if anything new and unknown has connected in the meantime then you'll be informed via a suitable pop-up alert. Which, initially at the list, will probably dwindle to nothing at all.
If you recognise a device as legitimate - a network storage device, say, or another system on your network - then right-click it, select Properties, check "I know this computer or device" and it'll be removed from the danger list. Anything that's clearly a part of the infrastructure, like the PC you're working on or your router will be flagged as green, but everything else will be marked as red: a potential intruder. The program requires no installation (the Windows build, anyway) - just run it, and SoftPerfect Wifi Guard will quickly scan your network and display any devices it finds. SoftPerfect Wifi Guard is a simple tool which makes it easy to detect intruders on your local network.
