What is the difference between PPTP, IPSec, and OpenVPN?



PPTP
Point-to-Point Tunneling Protocol (PPTP) is a basic VPN protocol. It uses very little resources and is relatively quick and responsive. PPTP is mostly supported for legacy devices and is NOT recommended unless you have no other choice.

Cisco IPSec
IPSec is a good protocol if you're using Apple devices. Both OS X and iOS natively support IPSec connections.

OpenVPN
OpenVPN protocol is a fast, secure VPN protocol which utilizes stronger encryption than PPTP. It offers VPN access through multiple UDP and TCP ports, making it very difficult to block. We highly recommend using OpenVPN over PPTP.
