An interesting thing happened on the road to mobility. In the past, road warriors only needed a VPN connection in order to access corporate resources from time to time. It’s what VPNs were designed to do, namely to take the cost out of modem banks and toll free phone lines, and replace them with cheaper connections to an Internet Service Provider. The VPN provided a way for users to set up temporary remote access connections over public networks. While VPN remote access remains a vital component of a mobility solution, it’s not the only requirement.
