What is the difference between pptp and ipsec

Windows Mac Android iOS. Best performing protocol. Fast speeds, even on connections with high latency and across great distances. Defeats deep packet inspection. Most reliable and stable, even behind wireless routers, on non-reliable networks, and on Wi-Fi hotspots. PPTP is a fast, easy-to-use protocol.

This article is meant to help shed some light on the situation and offer a comparison between the VPN protocols without getting too technical. PPTP works out of the box on pretty much any operating system and is easy to set up — on the other hand, PPTP as a protocol is also relatively insecure. It has been part of almost every operating system for more than 20 years and is very easy to set up.

All you need to connect is the address of the PPTP server, a username and a password. Unfortunately, time has taken its toll on PPTP: Vulnerabilities have been discovered that allow cracking the encryption used by PPTP, making the encrypted data visible to hackers. In order to successfully attack PPTP, quite a lot of computing resources are needed. Due to an inability to authenticate the remote partner, man-in-the-middle attacks mitm can easily be set up.

A successful mitm attack exposes the entire encrypted data transfer to the attacker. Another downside of PPTP is that it is nowadays often blocked by routers and firewalls by default.
