A virtual private network, or VPN, turns a public internet connection into a private network, offering you online privacy and anonymity. A VPN hides your internet protocol (IP) address, making your online actions almost untraceable. VPN services, in particular, allow private and encrypted connections, which provide greater anonymity than even a secured Wi-Fi hotspot.

You should utilize a virtual private network (VPN) when accessing the internet from a public area such as a coffee shop, hotel lobby, or any other facility that offers free public Wi-Fi (VPN).
