RDP is a network communication protocol developed by Microsoft. It helps a user to access and control a computer from a remote location, in this case, his residence. VPN is the creation of a smaller private network (in this case, your company’s network) on top of a larger public network such as the internet. Thus, the computers on your office’s VPN will be able to connect as if they are physically connected to the same switch. VPN permits applications that only work on a local network, to work on the internet. Thus, your employee when connected through RDP and VPN can access resources such as folders and other servers that are shared on this network. Thus, the combination of RDP and secured VPN offers you the much-needed data security.
