This article will talk about different VPN protocols. Network security depends on the type of VPN protocol, because it determines how two devices will exchange data with each other. What are VPN protocols? In fact, VPN protocols are special tools deployed to ensure an encrypted connection. Some of them may be more private, while others work faster. However, experts agree that any VPN protocol is not ideal.
The list of popular VPN protocols includes: OpenVPN;
Fireguard;
SoftEther;
IKEv2/IPSec;
L2TP/IPSec;
SSTP;
PPTP;
Proprietary Protocols.
Most VPN providers automatically connect to the best VPN protocol available. However, the VPN protocols themselves differ in the method of authorization (authentication) and the type of data encryption, which directly affects the level of user privacy.
