Quick answer: RDP (Remote Desktop Protocol) is a Microsoft protocol that lets you connect to and control a Windows computer or server over a network, seeing its full graphical desktop on your own screen. It is the standard way to administer a Windows VPS remotely.
With an RDP client - built into Windows, and available as a free app on Mac - you enter the server's address and your credentials to open its desktop as if you were sitting in front of it. You can then run programs, change settings, and manage the server graphically.
Because RDP is a common target for automated attacks, it should be secured: use strong passwords, restrict access to known IP addresses, enable Network Level Authentication, and keep the server patched. An exposed RDP port with a weak password is a frequent cause of compromise.
What port does RDP use?
RDP uses TCP port 3389 by default, though it can be changed to reduce automated attacks.
Can I use RDP from a Mac?
Yes - install the free Windows App (formerly Microsoft Remote Desktop) from the Mac App Store.
Every SoftSys managed Windows VPS includes RDP access, hardened by our team so it stays both convenient and secure.
