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, please
contact the network administrator of your company or organization.
