PPTP (Point to Point Tunneling Protocol) lower level encryption and lightweight VPN protocol offering basic online security with fast speeds. PPTP is built-in to cross platform and features 128-bit encryption.

Other technologies will be mentioned based on two major premises: popularity and availability. Microsoft is aware that detailed exploit code has been published for known weaknesses in the Microsoft Challenge Handshake Authentication Protocol version 2 (MS-CHAP v2). The MS-CHAP v2 protocol is widely used as an authentication method in Point-to-Point Tunneling Protocol (PPTP)-based VPNs. I gather the Windows VPN used to rely on PPTP, which is not considered secure. But in Windows 7/2008, it supports L2TP/IPSec, SSTP and IKEv2, and authenticates with EAP or CHAP/CHAPv2. That seems pretty up-to-date to me. Hello I have installed VM in Azure and installed RRAS role with VPN, NAT feature. For test purpose I have opened all ports on NSG and on server. From remote client/Win10 I tried to use differents VPN profile to connect but failed with all PPTP, L2TP, IKE2. //Alexander
These changes address most of the major security weaknesses of the orginal protocol. However, the revised protocol is still vulnerable to offline password-guessing attacks from hacker tools such as L0phtcrack. At this point we still do not recommend Microsoft PPTP for applications where security is a factor. Press Coverage of PPTP Version 2 Crack:
Microsoft Challenge Handshake Authentication Protocol version 2 (MS-CHAP v2) is a password-based authentication protocol which is widely used as an authentication method in PPTP-based (Point to Point Tunneling Protocol) VPNs.

If you are considering microsoft PPTP you may find this useful: PPTP FAQ. Also, PPTP vs. IPSec is a bit Fish vs. Bicycles - you might want to look at L2TP rather than straight IPSec (L2TP is built on IPSec, and is supported in Windows same as PPTP, and has decent open source implementations). Azure VPN Gateway connects your on-premises networks to Azure through Site-to-Site VPNs in a similar way that you set up and connect to a remote branch office. The connectivity is secure and uses the industry-standard protocols Internet Protocol Security (IPsec) and Internet Key Exchange (IKE). However the most common PPTP implementation, which ships with the Microsoft Windows product families, implements various levels of authentication and encryption natively as standard features of the Windows PPTP stack. The intended use of this protocol is to provide security levels and remote access levels comparable with typical VPN products Sep 26, 2012 · A death blow for PPTP CloudCracker self-experimentation by Jürgen Schmidt. Moxie Marlinspike's CloudCracker promises it can crack any PPTP connection – within a day, for $200. We tried it out with a real session. The VPN creates an encoded tunnel that doesn't even give snoopers at a Wi-Fi hotspot a chance - or does it
