Vino wants to know why people use a VPN. Leo says that a VPN is a virtual private network. It burrows an encrypted tube from a user's computer to the destination. It's very good for Privacy and Security. Especially when on public WiFi. VPNs can also mask physical location, so people don't know where users are. Great if a user wants to watch TV in another country like Great Britain.
What about the incognito mode in a browser? Leo says that private browser mode doesn't mask IP address. So people can still see where the traffic is going to.
And customers want to avoid low cost or free VPNs. They are selling information and aren't very secure.
