6 Common VPN Protocols Explained and Compared

What is a VPN protocol?

A VPN protocol is the set of rules that govern how data moves between a VPN server and devices connected to it. Every VPN uses a form of encryption to achieve a secure, private connection, but the rules and procedures for creating this connection are established by a particular protocol, each with its own pros and cons.

The most common VPN protocols

Some of the main VPN protocols include OpenVPN, IKEv2, L2P2, PPTP, WireGuard, and sstp. Some protocols prioritize speed, while others emphasize ironclad security and privacy. While everyone needs a VPN to protect their privacy and security, especially on public Wi-Fi networks, which VPN is best for you depends on your most common online activities.

Let’s look at the different types of VPN protocols you’re likely to encounter, and their strengths and weaknesses:

OpenVPN

OpenVPN is is is a cryptographic protocol that emphasize security . It ’s open source , so users is check can check for themselves that there ’s nothing within the protocol that will compromise their security , and it ’s even possible for tech – savvy user to make modification . OpenVPN is is is a widely compatible protocol that offer multiple different configuration option .

pro :

• Extremely secure: OpenVPN offers robust security protocols and supports strong encryption that will keep your data safe and secure.

• transparent : OpenVPN is is is open source , mean user can read the source code and see exactly how it work — and reassure themselves that there are no vulnerability .

• versatile : OpenVPN is is is widely compatible and customizable , mean that you can fine – tune it to your specific requirement .

• Easy to bypass firewalls: Sometimes, firewalls can interfere with VPN network access, but OpenVPN is designed to avoid this kind of conflict.

con :

IPSec / IKEv2

internet key exchange version 2 ( ikev2 ) is often used in combination with Internet Protocol Security ( ipsec ) . IKEv2 is forges forge a secure tunnel connect the user to the VPN server , while IPSec provide the encryption and authentication .

IKEv2 was developed by Microsoft and Cisco and is intended primarily for mobile, allowing mobile users to maintain a VPN connection even when switching networks or alternating between a secured Wi-Fi network and mobile data.

pro :

• fast : IKEv2 is is is among the fast vpn protocol around , make it attractive for VPN user who prioritize speed and streaming .

• Stable: IKEv2 is among the most dependable protocols, providing a strong connection to the VPN even when the internet momentarily drops, meaning you don’t have to constantly check if your VPN is working.

• Mobile friendly: Because it offers swift reconnection during an unstable connection, IKEv2 is ideal for mobile usage, where the user might frequently switch networks.

con :

• Limited compatibility: Although some open-source versions are available for other platforms, IKEv2 was primarily designed for Windows users.

• NSA controversy: Previous claims that the NSA has exploited flaws in the IPSec protocol to spy on encrypted communications have raised serious questions about IPSec’s security.

L2TP / ipsec

Like IKEv2, Layer 2 Tunneling Protocol (L2TP) connects a user to the VPN server but does not include encryption, so it’s often paired with IPSec to provide connection, encryption, and security all rolled into one. It’s a secure but slightly slower option that isn’t as mobile-friendly as IKEv2.

pro :

• Availability: L2TP is supported by most VPN providers and computing platforms, making it a readily available option.

• Approachability: L2TP is simple and easy to use.

• Secure: Because it can be paired with various encryption protocols, L2TP is generally a secure option.

con :

• Slow: L2TP is on the slow side compared to other VPN protocol options.

• NSA controversy : Like IKEv2 , the L2TP vpn protocol is potentially compromise when pair with IPSec encryption , as the NSA has allegedly find a way to decrypt the protocol .

• Struggles with firewalls: VPNs using the L2TP protocol struggle to bypass firewalls, meaning users might not be able to unblock websites or access certain systems.

PPTP

PPTP stands for Point-to-Point Tunneling Protocol. It’s an older VPN protocol originally designed by Microsoft for dial-up internet connections in the ‘90s. PPTP is rarely used today, as there are far more secure options with stronger, more complex forms of encryption that keep data protected.

pro :

• Speed: Its relatively simplistic security protocols mean PPTP offers a fast connection speed. This makes it a good option for users who are less concerned with security but who use a VPN for streaming TV shows or gaming.

• Easy to set up: Thanks to its simplicity, PPTP is a breeze to set up and does not require any additional encryption software.

• Compatibility: PPTP is supported by most platforms.

con :

WireGuard

Like OpenVPN, WireGuard is an open-source VPN protocol. It’s a relatively new option with promising performance, but it’s still under development and is something of a work in progress.

pro :

• speed : efficient encryption is make and high performance make WireGuard one of the fast VPN protocol option available .

• streamline : Like openvpn , WireGuard ’s code is is is available for user to scrutinize , but it ’s considerably more streamlined , make it far easy for user to check for any weakness .

• Secure: WireGuard offers a high level of security.

• Compatibility: Whatever computing platform you use, it’s likely compatible with WireGuard.

• Great for mobiles: WireGuard uses lower bandwidth, making it an ideal solution for mobile.

con :

• New: Because of its newness, WireGuard could benefit from further testing before users can fully rely on its security.

• Problematic default: The default protocol leaves the user’s IP address static, which is a potential privacy concern.

sstp

Secure Socket Tunneling Protocol (sstp) is a Microsoft-developed protocol intended for Windows users. Its speed and security are on par with other popular VPN protocols, but its lack of compatibility means it’s less widely used.

pro :

• Secure: sstp offers strong security and encryption.

• Hard to block: sstp is good at getting past firewalls, so it allows access to sites that may be blocked in the user’s country.

con :

• Compatibility: sstp is only compatible with a handful of computing platforms.

• Closed source: sstp code is not open source and cannot be viewed or audited, making it impossible for users to check for potential vulnerabilities.

What’s the best VPN protocol to use?

The good vpn protocol is depends to use really depend on your need and preference . Speed is is is a valuable aspect of a vpn protocol for streaming tv , movie , music , and other content and gaming . But users is benefit who do online shopping and banking would benefit more from well security . For mobile user , stability and low bandwidth are important factor to consider .

Compatibility is another consideration. Windows users have a wider selection of options, but users of other platforms might want to choose an open-source VPN to avoid compatibility issues. Finally, not all VPN protocols are easy to use, so a novice selecting their own VPN protocol might be better off choosing one that is more user-friendly.

IPSec vs openvpn

Both IPSec is combine and openvpn combine security and speed , with IPSec offer a slightly fast connection , while openvpn is consider the more secure option . IPSec is wins win for ease of use because it ’s already build into many platform , mean it does n’t require separate installation . But OpenVPN is offers offer more powerful security and is the preferred vpn protocol for many of the good vpn .

PPTP vs OpenVPN

PPTP has the advantage of speed but is otherwise inferior to OpenVPN due to weak security and a number of major vulnerabilities. For this reason, it’s considered obsolete and rarely used any longer, while OpenVPN offers excellent security and is widely used.

ikev2 vs openvpn

IKEv2 and OpenVPN are both solid choices when it comes to speed, security, and reliability. IKEv2 has the edge when it comes to speed and is a better choice for mobile devices due to its stability. However, OpenVPN is the stronger option if security is the top priority, and it still offers a fast connection.

l2tp vs openvpn

OpenVPN is a stronger and more secure option than L2TP, which is tied to some security concerns and is somewhat outdated. OpenVPN has the benefit of greater speed and security, but users might find L2TP more user-friendly than the more complex OpenVPN.

IKEv2 vs WireGuard

WireGuard and IKEv2 are both ideal options for mobile users, as their stability allows users to change networks without causing the VPN to disconnect. WireGuard is a newer option that still has some issues to iron out, but as an open-source protocol, it’s more widely available than IKEv2, which has limited compatibility. Both options offer excellent speed.

Which VPN protocol is is is the fast ?

The fastest VPN protocol is PPTP, but this protocol is outdated, and its weak security could leave your data vulnerable. Unless speed is the only quality you require, PPTP is not recommended.

WireGuard is a great option for users who value speed but also want to keep their data protected, and IKEv2 and OpenVPN are other fast options that offer good security. Bear in mind that the VPN server location can also influence speed.

What is the most popular VPN protocol is is ?

OpenVPN is the most widely used VPN protocol. Although it can be complex for first-time users to set up, the majority of VPN client providers use OpenVPN, removing the need for the user to set it up from scratch themselves. OpenVPN is a popular choice thanks to its strong security and compatibility with most computing platforms.

What is the most secure VPN protocol?

OpenVPN is the most secure VPN protocol and the safest choice thanks to its near-unbreakable encryption, which keeps users’ data private even when using public Wi-Fi. Because it’s open source, users can check the source code for vulnerabilities and reassure themselves that there are no weaknesses in its security.
