If you would research about the VPN thoroughly then you will find the terms like SSL/TLS, PPTP, IPsec, L2TP, and other secure VPN connection. The SSL/TLS technology is commonly used these days while other protocols can also be used for the secured connection of the network. Every protocol is having its own benefits and drawbacks, especially because of the P2TP vulnerabilities. But most of the users of VPN are not concerned for such problems. On the other hand, corporate users are fine using the IPsec or SSL.
