The Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP has been made obsolete by Layer 2 Tunneling Protocol (L2TP), IPSec and OpenVPN, but its still commonly used and natively supported by a lage scale of routers and clients.

PPTP (remote access) - Sophos Using the Point-to-Point Tunneling Protocol (PPTP), you can provide connections to your network through private tunnels over the internet. The protocol itself does not describe encryption or authentication features. However, the firewall supports several authentication options including Password Authentication Protocol (PAP), Challenge Handshake Authentication Protocol (CHAP), and … Light at the end of the tunnel: Answers to all your PPTP Aug 31, 2017

The following is an example of connecting two Intranets using PPTP tunnel over the Internet. Consider following setup: Office and Home routers are connected to the internet through ether1, workstations and laptops are connected to ether2. Both local networks are routed through a PPTP client, thus they are not in the same broadcast domain.

PPTP is a fast protocol if you compare with other tunneling protocols. But it has some vulnerabilities. Over the years, network attacks has increased and this VPN vulnerabilities become important gap. So, even it is a widely used VPN protocol, PPTP is not as secure as other tunneling protocols.
