If your unsecured Wi-Fi network worries you, bhv Software may have just the application for you.

Swiss Security Wireless Security is a new security package that guarantees protection from unwanted access by your neighbours or passers-by by monitoring access to the network.

It blocks threats, attacks, and intrusions, as well as DOS attacks and port scans.

The software itself creates a secure coded connection to all wireless devices, including your computer and the router, as well as other devices.

Once installed, it displays the security status of all devices, the status of Wi-Fi networks, and devices that are logging on and off the network.

It also helps to encrypt the network with WEP and WPA.

Swiss Security Wireless Security costs £20.
