Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of data 
from a remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-
based networks.

PPTP supports on-demand, multi-protocol and virtual private networking over public networks, such 
as the Internet.
