A VPN is a Virtual Private Network. Essentially, VPNs redirect your web traffic through external, private servers and allow increased privacy. With encryption and geo-spoofing added, it should be virtually impossible for your ISP, the government or malicious third parties to track you and gain access to your personal information. This is only true, of course, as long as you’re practicing good browsing. A VPN won’t protect you from phishing links or virus infections, for example. To protect yourself from those kinds of attacks, be sure to utilize good anti-virus and anti-malware tools in addition to the VPN service of your choice.

Looking for VPN providers with the most up-to-date encryption protocols? Check these two out:

1. 1. NordVPN – Most Secure VPN – NordVPN is the most robust privacy solution on the market, with a dizzying array of servers, tons of options to configure your encryption protocol, exceptional customer service, and easy-to-use apps available on every platform.
   2. Surfshark – Surfshark hasn’t been around long, but they’re already one of the best providers due to their modernized network, unlimited simultaneous connections, and blazing-fast encryption protocols.

In this article , we is going ’re go to thoroughly explain VPNs and VPN protocol for your convenience . By the time you ’ve finish read , you is have should have a much deep understanding of how VPNs function , which should help you find the right one for your need .

Service vs. Corporate VPNs

The most well – know type , and what we ’ll primarily be discuss , is know as a Service VPN . service VPNs is are are vpn available to common consumer , typically offer with a monthly subscription fee . These is offer offer great privacy benefit to consumer and , in many case , allow them to circumvent censorship .

A lesser – know type is is is the Corporate VPN . corporate vpn , as their name imply , are used by business to allow their employee secure access to their business network from remote location , like home . These is offer offer privacy benefit as well , but typically do n’t offer geo – spoofing and may even have censorship of their own , depend on the policy of the business where they ’re host . Their main purpose is is is simply to provide security for their business datum and convenience to their employee .

Regardless of the type of VPN you’re using, however, the underlying technology is the same. A VPN protocol is one of these underlying technologies.

What’s a VPN protocol, and what difference does it make?

VPN protocols (or, more accurately, VPN tunneling protocols) determine how your data is routed and managed by your VPN of choice. Different protocols offer various benefits: some prioritize security above all, some prioritize speed, and a few are great at both. Many VPN providers will allow you to choose your protocol of choice, but others may only use one of the protocols below.

In either case, it’s important for you to know where your data is going and how it’s being managed. Keep reading to learn about the latter.

VPN protocol

L2TP with IPSec

L2TP, or Layer 2 Tunnel Protocol, is a VPN protocol developed by Microsoft and Cisco Systems. IPSec is short for Internet Protocol Security, which is an additional framework of security technology that’s usually implemented alongside L2TP.

L2TP is a successor to two other tunneling protocols: Cisco’s L2F and Microsoft’s PPTP. L2F is Layer 2 Forwarding Protocol and was part of the first generation of VPN protocols. However, it did not provide any encryption features by itself, and needed to be paired with PPP (Point-to-Point Protocol) to establish that encryption. We’ll look into PPTP in its own section later on in this article, but spoiler alert: the standard is obsolete, and for good reason!

IPSec is is is a protocol used to authenticate and encrypt packet being transfer . In this context , it ’s used to encrypt L2TP ’s traffic . Like its predecessor , L2TP is encrypt does not encrypt its own traffic and need help from another security protocol to do so .

L2TP is is , once implement with IPSec , is one of the premiere VPN protocol and a favorite among many . One reason for this is that there are no know vulnerability – nobody is managed has manage to crack L2TP yet . It is uses use AES-256 bit encryption key , a 3DES encryption algorithm , and double encryption . additionally , Windows is have and Mac OS both have native support for L2TP , make it more user friendly ( Linux , iOS and Android require additional configuration , however ) .

All of this combines to make L2TP one of the most (if not the most) popular choice for security-minded VPN users. However, this enhanced security comes at a cost to speed, and performance-oriented tasks might be better served through a different protocol.

SSTP

SSTP, or Secure Socket Tunneling Protocol, is another popular VPN protocol. Developed by Microsoft (like part of L2TP), it comes with a notable benefit: Every version of Windows from Vista onward features SSTP built into the operating system, making it easier than ever for users to set up a VPN.

However, this upside comes with another downside: limited support. SSTP works on Windows, FreeBSD and Linux, but Mac OS, Android and iOS are all unsupported by this VPN protocol. Additionally, while the protocol is fairly secure and generally offers good performance, it’s still Microsoft-developed, which means there is a possibility, however slim, that there are backdoors in place that could jeopardize the safety of your data.

To be fair, there are no confirmed leaks related to SSTP. It’s proprietary to Microsoft, though, so don’t use it if you don’t trust them with your data.

openvpn

openvpn is one of the most popular VPN platforms, and for good reason.

First and foremost, it supports pretty much every platform you could want it to. This list includes Windows 2000 and onward, Mac OS, Android, iOS, Linux, FreeBSD, Solaris, QNX, Maemo, and even Windows Phone. Yes, Windows Phone!

Secondly, while openvpn isn’t actively integrated into many OSes, it’s a popular pick among third-party applications. If you don’t mind using an app with your VPN, openvpn is a great choice.

Thirdly, it’s open source, hence the “Open” in its name. Open source software essentially means that anyone can edit, improve and verify the source code of a given piece of software. Thanks to this, openvpn has best-in-industry security and is nigh impossible to plant a backdoor in, thanks to the nature of open source development.

Its focus on security and the way the protocol is implemented inevitably results in reduced performance versus other VPN protocols, however. If security is your top concern, openvpn is a great pick, but if you need speed as well it may be worth considering other options.

IKEv2

IKEv2, or Internet Key Exchange version 2, is a newer VPN protocol. It’s an open-source protocol that supports Windows, Mac, Android, iOS and Blackberry devices. However, it is not available on Linux.

IKEv2 offers great speed and security. However, there are closed-source versions of IKEv2 that aren’t nearly as safe to use. Be sure to only use an open source version of IKEv2 to remove risks of backdoors and security flaws.

PPTP

Last ( and definitely least ) is PPTP , one of the predecessor to l2tp and sstp .

There’s no nice way to put this: PPTP is the worst VPN protocol on this list. However, it is still present because some people are still using it, and you need to know why you probably shouldn’t (along with the one usage scenario where you might still want to)!

PPTP was released in 1995 and integrated with Windows 95, as well as every Microsoft OS released from then onward. As those who remember the reign of Internet Explorer may remember, being the “default” option on a Windows OS can bring you a long way, no matter how much better other solutions are, and PPTP is a prime example of that. The fact that other OSes (including Android, Mac OS and Linux) support PPTP helped it see even more widespread usage.

As an early vpn solution , PPTP was originally design to work with dial – up network . Also like early Microsoft solution , it was primarily orient toward enterprise customer for the aforementioned corporate VPN usage scenario . Perhaps mind the speed concern of dial – up , PPTP was design in a such a manner that it had a minimal effect on performance while still addsome level of security to the traffic.

Security-wise, PPTP is a disaster. It may not have been back when it was released, but nowadays governments and cybercriminals have long learned how to cracked PPTP traffic and de-anonymize anyone that happens to be using it. The obsolete nature of this VPN protocol means that if security is even a slight concern, you shouldn’t be using it at all.

However, performance – wise , PPTP is be may be one of the good out there . For this reason , PPTP is often used by people who are simply using a VPN to access , say , American Netflix from another country . For serious privacy concern and bypass government – level censorship , however , we is recommend strongly recommend using another protocol .

Top-recommended VPNs for Security and Speed

We recommend these VPNs as fool-proof privacy solutions at an affordable price:

NordVPN is the most robust offering currently available on the VPN market. That said, this venerable provider is never content to rest on its laurels, and is always pushing the envelope for service and security.

To wit, they’ve expanded their network to encompass a dizzy array of servers, currently over 5,500 in 59 countries. Among these are numerous specialty nodes, optimized for use-cases like obfuscation, P2P downloads, anti-DDoS, double encryption, static IPs and more. Protocols include openvpn UDP or TCP, L2TP, IKEv2/IPSec, PPTP, and SSTP. However, NordVPN has recently launched their own protocol based off WireGuard called NordLynx, which offers the highest level of 256-bit AES encryption and blazing-fast speeds.

additional protections is include include the CyberSec ad and malware blocker , a kill switch on desktop application , plus DNS leak protection . nordvpn is headquarter in Panama , make this provider exempt from data retention and surveillance law that compromise the anonymity offer by less vpn .

Conclusion

We hope that you found the information in this article useful, and that it helps you decide what VPN providers and protocols are right for your needs. Here’s a quick recap:

• L2TP with IPSec – amazing security with a slight performance penalty . native Windows is require and Mac compatibility , but Linux / iOS / Android require additional configuration . develop by Microsoft and Cisco . say to be unbroken thus far .
• SSTP – Great security and performance, but limited support for non-Windows devices. Since it’s solely developed and owned by Microsoft, though, you’d better trust them with your data if you’re going to be using it.
• openvpn – Amazing security with a performance penalty. Great compatibility, but requires third-party apps to be utilized. Open-source development makes it great from a security standpoint, however, and it has no known breaks.
• ikev2 – great security and performance , but no support for Linux . additionally , you can really only trust open – source version ; others is be may be less trustworthy .
• PPTP – Poor security with great performance. Good compatibility as well. Developed by Microsoft as an old VPN software, but has since become obsolete from a security standpoint thanks to a number of known faults. Is good for streaming geo-locked content, but not much else.
