Should I use IKEv2 or WireGuard?
Firewall ports
IKEv2 is easier to block than OpenVPN due to its reliance on fixed protocols and ports. OpenVPN can be easily configured to run on any port using either UDP or TCP thereby easily bypassing restrictive firewalls. WireGuard® uses the UDP protocol and can be configured to use any port.
The best Surfshark VPN protocol largely depends on the device you're using or the reason you need a VPN: Wireguard is good all around, especially when speed is the issue. IKEv2 is on par with WireGuard, and is really good with mobile. OpenVPN usually works best for routers.
Performance: In many cases IKEv2 is faster than OpenVPN since it is less CPU-intensive. There are, however, numerous variables that affect speed, so this may not apply in all use cases. From a performance standpoint with mobile users, IKEv2 may be the best option because it does well establishing a reconnection.
WireGuard is extremely secure, but only when it's coupled with a solid VPN. WireGuard has its own state-of-the-art security protocols that ensure there are no data leaks or risks of cyberattack to its users.
Wireguard is the Best VPN Protocol
It was originally released for the Linux kernel, but is now cross-platform and can be widely deployable. Though WireGuard is still under development, it can already be considered as one of the most secure, fast, and easy-to-use solutions in the VPN industry.
WireGuard is the fastest VPN protocol we have tested — much faster than OpenVPN. This makes WireGuard the fastest VPN protocol we have tested (when used it with NordVPN on a nearby server).
When to use it: IPSec/IKEv2 stability guarantees that you won't lose your VPN connection when switching from Wi-Fi to mobile data, so it could be a good choice when you're on the move. It also quickly bypasses firewalls and can offer high speeds on streaming platforms.
IKEv2 is very safe to use, as it has support for powerful encryption ciphers, and it also improved all the security flaws that were present in IKEv1. Also, IKEv2 is an excellent choice for mobile users due to its MOBIKE support which allows IKEv2 connections to resist network changes.
WireGuard is considered the fastest among all the VPN protocols. If you wish to stream and download P2P files faster on the network, make sure to use WireGuard after signing in to PureVPN. Besides WireGuard, L2TP and IKEv2 are also considered fast, while OpenVPN and SSTP are slower than other VPN protocols.
Because the IKEv2 only uses the UDP port 500, it can be blocked by a firewall. There are a few security issues that have been detected concerning the protocol. First is the possibility of being hacked if the password is weak. This is a fault on the user's side and can easily be fixed.
Which VPN type is better?
OpenVPN (Open-Source Virtual Private Network) is the gold standard in VPN protocols. It's reasonably fast and is configurable with most ports and encryptions. It works on all major platforms, including Windows, macOS, Linux, Android, and iOS. This is ideal if you plan on running your VPN on multiple devices.
WireGuard offers a more reliable connection for mobile users than OpenVPN because it handles network changes better. OpenVPN adds a data overhead of up to 20%, whereas WireGuard uses just 4% more data (compared with not using a VPN). VPN services need to include mitigations to ensure user privacy when using WireGuard.
Is WireGuard secure? WireGuard is very secure. It uses faster, state-of-the-art secure ciphers and algorithms. Its small codebase makes it easier to audit while offering a smaller attack surface for anyone trying to hack it.
SUMMARY: WireGuard is the most efficient VPN protocol when it comes to mobile data usage. In our tests, it increased data consumption by just 4.5%. By contrast, the industry-standard protocol, OpenVPN, uses the most data.
It is currently under heavy development, but already it might be regarded as the most secure, easiest to use, and simplest VPN solution in the industry.
WireGuard is a VPN protocol —the way that a client (like your computer or phone) communicates with a VPN server. You might also hear “WireGuard” refer to the app you can run on your devices as well. It only supports UDP, which uses no handshake protocols. That's one of the reasons why it's so fast.
NordLynx is a technology we built around the WireGuard® VPN protocol. It lets you experience WireGuard's speed benefits without compromising your privacy.
Firewall rules must pass traffic on WAN to the WireGuard Listen Port for a tunnel if remote WireGuard peers will initiate connections to this firewall. The protocol is always UDP, and the default port is 51820 .
Benchmarking. These benchmarks are old, crusty, and not super well conducted. In the intervening time, WireGuard and IPsec have both gotten faster, with WireGuard stil edging out IPsec in some cases due to its multi-threading, while OpenVPN remains extremely slow.
IKEv2 provides the following benefits over IKEv1: In IKEv2 Tunnel endpoints exchange fewer messages to establish a tunnel. IKEv2 uses four messages; IKEv1 uses either six messages (in the main mode) or three messages (in aggressive mode).
Is WireGuard better than IPsec?
IPsec and WireGuard VPNs are comparable performance-wise across most platforms, with WireGuard being slightly faster. WireGuard itself has conducted an in-depth performance study, comparing the throughput and latency in IPsec and WireGuard connections with similar encryption options on a powerful Linux computer.
UDP is faster than TCP connections so that an IKEv2 protocol will give better performance in applications such as gaming and video streaming. It's very popular due to the fact that it demands less CPU performance and offers a reliable connection.
1. NordVPN – incredibly strong and secure VPN. NordVPN is the most secure VPN on the market. It is based in a privacy-friendly location, uses the newest encryption technology and security measures, as well as offers numerous additional features for safe browsing, entertainment, and more.
IPSec is considered secure and reliable, while IKEv2 is extremely fast and stable – IKEV2 offers quick re-connections when switching networks or during sudden drops. Thus, a combination of IKEv2/IPsec forms one of the best VPN protocols that exhibits the advantages of the two.
- OpenVPN is fast, flexible, and secure. ...
- PPTP should almost never be used. ...
- L2TP/IPSec is a step up from PPTP, but it's also one of the slowest connections, and its security is questionable.
- SSTP is pretty good for Windows users.
ExpressVPN is the best VPN for ethical hackers, and for good reason. With over 3,200 high-speed servers in 160 locations across 94 countries, it's easy to find a nearby server to mask your IP address that still offers fast speeds.
In terms of banking, without a VPN, your transactions, along with information such as your name and bank details, can potentially be accessed by hackers and used to steal your money or identity. However, if you use a VPN, your data traffic is additionally encrypted, so that your transactions are safe from prying eyes.
In early 2021, more than 21 million Android users were exposed. Three different free Android VPNs were targeted: SuperVPN, Gecko VPN, and Chat VPN. The cyberattackers harvested deeply sensitive user information and advertised the data cache to the highest bidder on a popular hacker forum.
Using OpenVPN with UDP is a better choice for almost all general VPN connections. That's because UDP is faster than TCP and it uses less data. Applications will continue to use TCP for their connection inside your UDP VPN tunnel, which means any services that require TCP's guaranteed packet delivery can still have it.
WireGuard uses the latest encryption protocols (ChaCha20, Curve25519, BLAKE2s, SipHash24, HKDF, etc.), making it arguably more secure than older, more established VPN protocols. From a user's point of view, the clearest benefit of WireGuard is a faster connection time.
Can WireGuard bypass firewall?
Like any VPN protocol, WireGuard should be able to bypass firewalls. It routes your traffic through a new IP which isn't blocked by the firewall, after all. But if the network admin blocks all UDP ports, they'll block all WireGuard traffic since it only runs over UDP, and can't use TCP port 443 (the HTTPS port).

Simply put, a VPN will slow your internet connection down, because your internet traffic is going through the VPN server: it's an extra step in the process. However, a premium VPN like NordVPN is so fast that you won't normally notice any increased latency; the slowdown is usually imperceptible for the user.
By default, WireGuard doesn't support IP address flexibility and even stores them indefinitely on the hosting server to maintain a connection. Even though you can go around this shortcoming by using privacy-oriented VPN providers that don't keep logs, it's still something to consider before signing up.
WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs), and was designed with the goals of ease of use, high speed performance, and low attack surface.
