PPTP-protocol

When you choose a VPN service provider, it’s important to understand the protocol or protocols that the company offers. Each VPN protocol affects you in a different way, and each may not be best utilized for what you have in mind. In this article, we will discuss the PPTP protocol.

PPTP

PPTP, or Point-to-Point Tunneling Protocol, was developed for dial-up networks. Think of it as the grandfather of all protocols. Microsoft charged a consortium with developing this protocol and it has long been the standard for businesses worldwide.

Today, the protocol is considered to be outdated. It is often not enough to provide the type of privacy that most customers are looking for. In fact, PPTP is a VPN protocol only; it relies on a variety of authentication methods in order to provide security. Even though it is a bit outdated, it is extremely easy to set up and use, making it a still-popular choice among consumers and businesses alike.

Security Flaws

PPTP is now typically found using 128-bit encryption keys, though this wasn’t always the case. In 1999 a number of vulnerabilities were discovered. Using the MS-CHAP v2 Authentication exploit, PPTP was cracked in a matter of two days. The flaw has since been adequately patched, but Microsoft still recommends that VPN users choose L2TP/IPSec or SSTP protocols instead.

The security flaws of PPTP are not known to the public alone. The NSA easily decrypts PPTP communications. Although there is no certain proof, it is thought that the NSA has even decrypted older data encrypted with PPTP.

Positives

  • Built in to almost every platform
  • Easy to set up and use
  • High speeds

Negatives

  • No longer secure
  • Has been compromised by the NSA

Although PPTP was the standard when dial-up was still the only choice, the protocol is no longer considered secure. If you are looking for a VPN to simply help you bypass geo-restrictions, it is adequate. If, on the other hand, you want a VPN to protect your anonymity and privacy, PPTP should be your last choice.
