It may work on routers lacking support for any other VPN types out of the box. It's not as reliable as OpenVPN over networks experiencing issues, leading to connection drops. Therefore, from a security perspective we rate it somewhere in-between PPTP and OpenVPN: overall good for security as long as neither of the end-points client or server are targeted by highly skilled attackers.
It is the protocol used with our iOS app, being natively supported on iOS. OpenVPN is secure and reliable. However, just running over common ports is not enough as any decent DPI would immediately identify it. For that reason, an extra obfuscation layer needs to be implemented and we use 2 different obfuscation methods to make it stealthier.
Synology NAS, Chromebooks. It can also be used to supply a protected path through a network. At its basic description, it is a communications protocol to encapsulate at a peer level or lower.
Tunneling protocols are also transporters of multiple protocols. They are vehicles for encrypted VPNs. It is developed by Microsoft.
With its use, users can remotely access corporate networks from any Internet Service Provider ISP that supports the protocol. PPTP is often favored because it is easy to use and to set-up.
However, it can be crude and in terms of functionality and efficiency, it may be outdone by its descendants such as L2TP. PPTP is rather ancient but still considered popular until now. In PPTP, control and data streams are separated. Layer 2 Tunneling Protocol or L2TP is a tunneling protocol that allows remote users to access the common network.

Want to use a VPN? Some VPN providers may even provider you with a choice of protocols. That means attackers and more repressive governments would have an easier way to compromise these connections.
Yes, PPTP is common and easy to set up. PPTP clients are built into many platforms, including Windows.
In Summary : PPTP is old and vulnerable, although integrated into common operating systems and easy to set up. Stay away. It can be configured to run on any port, so you could configure a server to work over TCP port This makes it difficult to block completely.
OpenVPN has become a popular standard. Connecting to an OpenVPN network requires a a third-party application — either a desktop application or a mobile app. This is the one you should probably use. IPsec encryption should be secure, theoretically.
There are some concerns that the NSA could have weakened the standard, but no one knows for sure. Either way, this is a slower solution than OpenVPN.
It can be configured to use very secure AES encryption, which is good. Still, this is better to use than PPTP. OpenVPN seems to be the best option. Image Credit: Giorgio Montersino on Flickr.
