Your employer requires all mobile devices have a VPN client installed. The VPN client should be enabled whenever public or otherwise untrusted wireless networks are used. What is the benefit of using a VPN?
A Virtual Private Network (VPN) provides an encrypted tunnel to connect to networks. It can be used to securely connect from a home office to a corporate network or as an additional layer of security when using public wireless networks (e.g. the free WiFi at a coffee shop).
A virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network Applications running on an end system (PC, smartphone etc) across a VPN may therefore benefit from the functionality, security, and management of the private network Encryption is a common, though not an inherent, part of a VPN connectionVPN technology was developed to allow remote users and branch offices to access corporate applications and resources To ensure security, the private network connection is established using an encrypted layered tunneling protocol, and VPN users use authentication methods, including passwords or certificates, to gain access to the VPN
