VPN Encryption Protocols: The Real Power of Virtual Private Networks

Posted on by Clare Louise

Virtual Private Networks (VPNs) are highly sought-after for their online security benefits. VPNs are especially popular among Koreans who want to enjoy banned Korean contents amidst their stringent laws. Just search “한국 vpn” to know the extent of popularity of Korean VPN brands. But what is the secret behind their online security?- their protocols. Let’s look at some of the most widely used VPN protocols.

OpenVPN

OpenVPN is probably the most secure VPN encryption protocol and it’s rightfully used by most commercial VPN providers. It is an open-source encryption, that means it’s codes are publicly available for anyone to examine them. It’s security protocol uses both SSL (Secure Sockets Layer) and TLS (Transport Layer Security), hence the effectiveness. It’s versatility and tight security makes it dominate even the reliable Korean vpn 추천charts.

SSTP

SSTP (Secure Socket Tunneling Protocol) is a SSL-based Microsoft-owned protocol. It offers most of the advantages that OpenVPN offers. But the main difference is that SSTP exclusively works for Windows and that it is not open-source, unlike OpenVPN. Furthermore, the association with Microsoft guarantees support from the company if some problem arises in the future.

PPTP

Point-to-Point Tunneling Protocol (PPTP) is one of the oldest, yet still popular, VPN protocols. It forms an encrypted connection or tunnel to confine and encrypt data. It is built-in on most older operating systems of Windows, Mac, and Linux. 

L2TP/IPsec

 Layer 2 Tunneling Protocol with Internet Protocol Security or L2TP/IPsec is a Microsoft protocol that forms a secure connection between you and other servers in the VPN you use. It double-encapsulates data which provides security better than PPTP, but slows down the speed. By observing its features, it is a good choice for phone users with non-critical use.

IKEv2/IPsec

Internet Protocol Security with Internet Key Exchange version 2 (IKEv2/IPsec) might be a mouthful to say, but it is an incredibly secure, and fast, VPN protocol. It is pre-configured in most OD, and works exceptionally well with mobile devices. IKEv2/IPsec is a great vpn 추천for those mobile users who want a fast and secure VPN, and can quickly reconnect if somehow the connection is temporarily lost.     

WireGuard

WireGuard is a newer protocol that plans to offer security and performance even better than the OpenVPN. If you are a Korean who lives outside Korea but wants to enjoy blocked Korean websites, you’ll definitely find this protocol in your 한국 vpn. This protocol avoids common issues of IPsec and OpenVPN- frequent disconnection, complex setup, heavy codebases, etc.
