Fully encrypt your data on all devices and access any website without restrictions.
VPN is mostly used to protect data transmitted over unreliable networks. For example, to protect data on unsafe public Wi-Fi hotspots.
You can also use a VPN to hide the IP or the country where the customer is located. This is necessary to access resources that may be blocked by network providers.
VPN provides an encrypted and secure connection (think of a tunnel) between the client and the VPN server for data transfer.
