Virtual private networks (VPNs)
Use your device to connect to virtual private networks (VPNs), which allow you to
access resources inside a secured local network from a public network. For example,
VPN connections are commonly used by corporations and educational institutions for
users who need to access intranets and other internal services when they are outside
of the internal network, for example, when they are traveling.
VPN connections can be set up in many ways, depending on the network. Some
networks may require you to transfer and install a security certificate on your device.
For detailed information on how to set up a connection to your virtual private network,
