From the developer:
iNet Guardian protects your network by notifying you about the workstations that are connecting or disconnecting from the internet gateway. WEP, WPA or WPA2 wireless security protocols can easily be hacked by third parties and your confidential information such e-mail password, online bank account password or credit card details can be hijacked.
