Give it a try to see for yourself. The provider’s virtual private network is large, with more than 53,000 IP addresses on 684 servers in 24 countries. In fact, right now, Wireguard mostly just works on Linux distributions. Also, IKEv2 is an excellent choice for mobile users due to its MOBIKE support which allows IKEv2 connections to resist network changes. We already mentioned that IKEv2 handles the SA attribute, but what is SA? IKEv1 doesn’t have built-in NAT traversal like IKEv2 does. OpenVPN. In fact, it’s one of the fastest VPN protocols that are available to online users – potentially even as fast as PPTP or SoftEther. IKEv2 encryption supports more algorithms than IKEv1. OpenVPN: This is currently the VPN standard used by most commercial VPNs; most devices support it. Thus, you won’t need any third-party apps. It’s not even new at all…. L2TP stands for Layer 2 Tunneling Protocol. The companies behind IKEv2―Microsoft and Cisco―may also have corporate interests in building vulnerabilities around this protocol, especially upon the government’s request. That is why IKEv2 is very popular right now―it can prevent mistakes like this for your completely legitimate needs. For one, SoftEther is much harder to block with a firewall because it runs on port 443 (the HTTPS port). IKEv2 (Internet Key Exchange version 2) is a VPN encryption protocol that handles request and response actions. Here’s an in-depth guide we wrote about it. According to these benchmarks, Wireguard is much faster than IPSec, though that doesn’t necessarily mean it’s faster than IKEv2 for now since IKEv2 is faster than IPSec too. SSTP is only built into Windows systems (Vista and higher), and it can further be configured on routers, Linux, and Android. Read our reviews of some of the best providers below to find out the VPN provider’s logging policy, how big or small their networks are, how to reach their customer support, and if their services are worth their rates. Among the features of IKEv2 are built-in DoS protection, NAT-T, and EAP authentication. Still, we do recommend choosing a VPN provider that offers access to multiple protocols alongside IKEv2. Yes, IKEv2 is a good option for a safe, smooth online experience. Regarding cross-platform support, IKEv2 is a bit behind OpenVPN, but it does work on BlackBerry devices. However, SSL 3.0 is vulnerable to the POODLE attack, making SSTP, and other software and browsers that use SSL 3.0, vulnerable. Lastly, IKEv2’s security is unquestionable since it refuses to perform any further actions until the identity of the requester is verified. IKEv2 supports IPSec’s latest encryption algorithms, alongside multiple other encryption ciphers. We’d still recommend you use either OpenVPN or SoftEther, but if those options aren’t available for some reason, IKEv2 works well too – especially if you use your mobile and you travel quite often. If a VPN provider logs and stores even a small amount of personal details, then it will be easy to track a user. All these make IKEv2 a highly secure and reliable VPN protocol. Besides that, you should know that IKEv2 won’t be the only option at your disposal. It’s secure and isn’t clouded by any corporate interests because it is open-source. Well, if this happened to a seasoned hacker, this could happen to anyone. Windows 7, Windows Server 2008, Cisco routers, and macOS devices also natively support IKEv2, but other devices have not followed suit. Microsoft had fixed this, but the company has also recommended using a different VPN protocol. All these features make it a premium VPN provider. It does that by first authenticating both the client and the server, and then agreeing on which encryption methods will be used. However, being primarily used in corporate environments, IKEv2 doesn’t have native support for Linux, and its lack of configurability can be a drawback. The IKEv2 VPN protocol uses encryption keys for both sides, making it more secure than IKEv1. Unfortunately, the details are a bit vague, and there’s no exact way to guarantee that the presentations are valid. If you’d like to read more about IPSec, check out our article about it. Also, IKEv2 isn’t completely closed-source since open-source implementations of the protocol exist. In terms of online speeds, IKEv2 is usually faster than OpenVPN – even when OpenVPN uses the UDP transmission protocol. For example, PPTP is no longer natively available on iOS 10 and macOS Sierra. IKEv2 is generally a much better choice than PPTP simply because it’s way more secure than it. Also, it’s true that Microsoft worked on IKEv2, and that’s not a very trustworthy corporation. IKEv2 VPN support is basically when a third-party VPN provider offers access to IKEv2/IPSec connections through its service. This is great when you are on the go, and you are constantly switching between your mobile data and a wireless network. However, we can’t deny the fact that OpenVPN being open-source makes it a more appealing option than IKEv2. Learn more about Lightway. Although VyprVPN does not allow P2P connections, its VPN service is of high quality. Narrow support: Most VPN providers are hesitant in including IKEv2 mainly due to its limitation in terms of supported devices. Not to mention that even if an IKEv2 connection goes down, it’s restored immediately. Still, that normally isn’t a huge security concern if you are using a strong password. As for the IKEv2 issue, it seems that it could be relatively easily hacked if the login password that is used by it is weak. Two factors to consider when choosing a VPN provider: Make sure you check these factors when you do your research before selecting a VPN provider and the VPN protocol to use. That, and Snowden has claimed that the NSA have weakened L2TP/IPSec, though there’s no real evidence to back that claim up. It’s also relatively faster, although several factors impact VPN speed. Besides that, there’s also the fact that SSTP only uses TCP, which is slower than UDP (the transmission protocol used by IKEv2). Wireguard is a very new open-source VPN protocol that apparently aims to become significantly better than IPSec (the tunneling protocol IKEv2 is based on). That means they tend to offer the same level of security. Tim has been writing content and copy for a living for over 4 years, and has been covering VPN, Internet privacy, and cybersecurity topics for more than 2 years. It does that by generating the same symmetric encryption key for both entities. All these features make it a premium VPN provider. The German magazine Der Spiegel released leaked NSA presentations that claimed the NSA was able to exploit IKE and ISAKMP to decrypt IPSec traffic. The same can be said if you are using a third-party VPN service since they’ll be handling the IKEv2 login passwords and authentication on your behalf. Before we start, we should mention that when we’ll be discussing IKEv2 in this section, we’ll be referring to IKEv2/IPSec since that’s the protocol VPN providers generally offer. Therefore, it is not easily blocked by a VPN blocker. Overall, it would seem that IKEv2/IPSec is a better choice for mobile users, whereas L2TP/IPSec works well for other devices. Like any development in technology, IKEv2 has its own set of disadvantages (aside from the advantages) which help determine if it is the right VPN protocol for you. Used together, L2TP and IPsec are much more secure than PPTP (Point-to-Point Tunneling Protocol) but are still more suited for anonymization than for security. It relies on IPSec as the authentication suite, and both L2TP and IPSec are developed by Microsoft. We went back to our list of top VPN providers and found out that most of them already support the IKEv2 VPN protocol. Still, we should address three security-related issues regarding IKEv2/IPSec: Back in 2018, some research came to light that highlighted the potential security weaknesses of both IKEv1 and IKEv2. It is easy to set up since there’s no need for additional software. PPTP: Point-to-Point Tunneling Protocol was developed for dial-up networks, making it a popular choice for corporate VPN networks. HideIPVPN is among our top 10 VPN providers, although its network is not as huge as the other providers on our list. If youâre still not sure which VPN protocol to choose, simply let the ExpressVPN app automatically select the best one for you. Luckily, the problem can be avoided if stricter configurations are used, and if the client systems are carefully segregated on multiple service access points.
