A VPN (Virtual Private Network) can be thought of as your private tunnel between your computer and the Internet. This, effectively, makes all communication to and from your computer ‘invisible’ to anyone around you. In fact, your data (information) is encrypted making it meaningless to anyone else.
The Wifi Protector VPN uses OpenVPN technology which is the most secure VPN protocol available today. Unlike other VPN products, Wifi Protector offers VPN protection completely free. Also, Wifi Protector offers “automatic protection mode” which ensures that the protection will be automatically enabled for you.
Likewise, if Wifi Protector detects an intruder, all the communication from your computer will be isolated and the attacker will not be able to see your internet activity.
