    RDP vs VPN: Understanding the Key Differences

    Both VPN (virtual private network) and RDP (remote desktop protocol) are remote access technologies. You use an internet connection to access a computer that’s in a different location than yours and get the benefits as if you were using that computer.

    There’s one key difference between a virtual private network and a remote desktop protocol – the level of control you get. A VPN server only provides you with internet traffic routing, encryption, and some other benefits. You continue using your machine for everything else.

    Remote desktop protocol gives you access to the machine itself. You may get different levels of permissions (ranging from limited access to full administrative privileges), but in all cases you’ll get to control the machine itself to some extent.
