VPN Protocol Comparison – Guides To Choose Best Protocol
A virtual private network is able to maintain privacy through the use of security procedures and tunneling protocols, such as PPTP, L2TP, OpenVPN, etc. Today we will talk about the difference between them so that you can enjoy the best service by choosing the best protocol.
PPTP (Point to Point Tunneling Protocol) allows remote users to connect to a private network and is often used by remote employees to connect to their company’s network securely. This type of protocol uses the already established internet connection to connect to the VPN through the use of logon and password.
However, it is a good, lightweight VPN protocol offering basic online security with fast speeds. You can choose the best and reliable company such as VPN Academy to have PPTP protocol in your system. PPTP is built-in to a wide array of desktop and mobile devices and features 128-bit encryption.

L2TP is a more secure choice with Layer 2 Tunneling Protocol. It works together with the IPSec protocol that utilizes better-protected encryption algorithms than what’s used with PPTP. The combination of the 3DES encryption algorithm and 256-bit keys is what makes L2TP encryption more powerful. It is based on software that is installed on a user’s computer which then encrypts and decrypts each packet. The result of this protocol is that once it is set up, you have a virtual private network to the company no matter where you are – as long as you use the computer the software is installed on.
OpenVPN is an open-source software program that performs virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities along with the best cost performance (also called as 최고의 비용 성능 in the Korean language). It uses a custom security protocol that uses SSL/TLS for key exchange. It is capable of traversing network address translators (NATs) and firewalls.

OpenVPN supports most computers and is easy to set up with software. It is stable/reliable even on non-reliable networks, behind wireless routers, and on Wi-Fi hotspots. With the highest encryption, it authenticates the data on both ends of the connection through digital certificates.
