L2TP/IPSec provides AES-256 bit encryption, one of the most advanced encryption standards that can be implemented. L2TP encapsulates the data, but isn’t adequately encrypted until IPSec wraps the data again with its own encryption to create two layers of encryption, securing the confidentiality of the data packets going through the tunnel. Layer 2 Tunneling Protocol (L2TP) is used in conjunction with Internet Protocol Security (IPSec) to create a more secure tunneling protocol than PPTP.
With known vulnerabilities dating as far back as 1998, and the absence of strong encryption, you’ll want to avoid using this protocol if you need solid online security and anonymity – government agencies and authorities like the NSA have been able to compromise the protocol’s encryption. While it boasts fast connection speeds, the low level of encryption makes PPTP one of the least secure protocols you can use to protect your data. It’s one of the fastest VPN protocols because of its low encryption level. PPTP is one of the easiest protocols to configure, requiring only a username, password, and server address to connect to the server.

Developed by Microsoft and released with Windows 95, PPTP encrypts your data in packets and sends them through a tunnel it creates over your network connection. Point to Point Tunneling Protocol (PPTP) is one of the oldest protocols still being used by VPNs today.
The most commonly used tunneling protocols in the VPN industry are PPTP, L2TP/IPSec, SSTP, and OpenVPN - and the world's best VPN services should offer most or all of them.
There are many types of VPN protocols that offer varying levels of security and other features.
