SpyderSoft Wi-Fi Defense(TM) was designed with the mainstream, non-technical consumer in mind, yet is powerful enough to offer security benefits to even the most advanced user. The technology detects all devices on the network, provides identifying information to assist the owner in designating each as Friend or Foe, and seamlessly locks-down the network to allow only approved devices.

Adding a new device or allowing a visitor to join the network is also an easy task, and the application ensures that you maintain a locked-down network. At all times, SpyderSoft Wi-Fi Defense(TM) continues a background scan to detect new and/or unauthorized devices.
