NordVPN supports a number of security encryption protocolsto provide aVPN service. The security levels and purposes of these VPN protocols are different, but so are our customers’ needs. We encourage you to take a closer look at the strengths and weaknesses of each VPN protocol. While we want you to be able to choose freely, we also feel it’s our duty to advise you on what might suit you best.
1. OpenVPN
OpenVPN is a mature and robust piece of open-source software that enables us to provide a reliable and secure VPN service. It is a versatile VPN protocol that can be used on both TCP and UDP ports. OpenVPN supports a great number of strong encryption algorithms and ciphers: to ensure the protection of your data, we use AES-256-GCM with a 4096-bit DH key. If you are conscious about your security and are wondering what the most stable NordVPN protocol is, we recommend OpenVPN.
2.IKEv2/IPsec
IKEv2/IPsec significantly increases the security and privacy of users by employing strong cryptographic algorithms and keys. NordVPN uses NGE (“next-generation encryption”) in IKEv2/IPsec. Phase1 keys are generated using AES-256-GCM, SHA2-384, and PFS (Perfect Forward Secrecy) using 3072-bit Diffie-Hellman keys. IPsec then secures the tunnel between the client and server, using strong AES-256 encryption. This VPN protocol provides the user with peace-of-mind security, stability, and speed.
3. WireGuard (NordLynx)(Recommended by NordVPN and used by default in most of our apps)
WireGuard is the newest and fastest tunneling protocol, and the entire VPN industry is talking about it. It uses state-of-the-art cryptography that outshines the current leaders, OpenVPN, and IPSec/IKEv2. However, it’s still considered experimental, so VPN providers need to look for new solutions (likeNordLynx by NordVPN) to overcome WireGuard’s vulnerabilities.
Modern, extremely fast, and incredibly lean in its architecture, WireGuard is backed by thorough academic research. WireGuard consists of only 4,000 lines of code, making it easy to deploy, audit, and fix. To put it into perspective, OpenVPN runs on 400,000 lines of code, meaning that WireGuard makes up only 1% of OpenVPN’s massive architecture.
NordLynx is currently used by default in NordVPN apps. If you’re wondering which VPN protocol is best for gaming or other online speed-dependent activities, the answer is always NordLynx.

What is the best VPN protocol setting? ›
The best VPN protocol for you depends on a number of factors, including what device you're using, how much balance between security and speed you want, what type of activities you're doing online, and more. OpenVPN and WireGuard are generally considered the best VPN protocols for day-to-day use.
Should I use NordVPN TCP or UDP? ›
TCP is more reliable than UDP. It transfers your data packets from your device to a web server. UDP is faster and simpler, but it doesn't guarantee the delivery of packets.
Does VPN protocol matter? ›
❌ VPN protocols determine your connection speed: only partially, as there are many other factors that impact your connection speed. ❌ VPN protocols determine your connection security: they do, and they don't. The encryption algorithms do most of the “securing” by encrypting your data.
Should I use WireGuard or IKEv2? ›
Based on these findings, if you're looking for the fastest secure tunneling protocol, you should go with NordLynx (or WireGuard). The second fastest will be IKEv2, which can confidently hold its own even when connecting to the other side of the world.
What is the difference between NordVPN IPv4 and IPv6? ›
Unlike the IPv4 protocol, IPv6 won't ever run out of unique IP addresses — it can provide nearly 3.4×10^38 of them. Furthermore, some argue that IPv6 is a more efficient technology, providing better quality and connectivity.
What are the 3 most common VPN protocols? ›
The most common VPN protocols are OpenVPN, WireGuard, L2TP/IPsec, IKEv2/IPsec, PPTP and SSTP. These protocols offer different trade-offs between security, speed and compatibility, so the best option will depend on your specific needs.
What protocol does always on VPN use? ›
In Windows Server 2022, Always On VPN includes support for the Internet Key Exchange version 2 VPN protocol for improved performance and security; Microsoft Entra ID (formerly Azure Active Directory) for conditional access policy integration; and XML profile configuration via PowerShell, Microsoft Endpoint ...
What is the least secure VPN protocol? ›
Point-to-point Tunneling Protocol (PPTP) is the oldest and least secure VPN protocol. Due to its weak encryption and known security vulnerabilities, PPTP is considered obsolete and isn't typically used by reputable VPN providers.
What is the new NordVPN protocol? ›
NordLynx is NordVPN's revolutionary technology built around the WireGuard® VPN protocol. It helps you connect to NordVPN servers faster and improves your VPN connection speeds without compromising security or privacy.
TCP is best used for direct communication in which a reliable connection is needed, such as web browsing, email, text messaging, and file transfers. UDP is best used for live and real-time data transmission when speed is more important than reliability.
How do I change the protocol on NordVPN? ›
Open NordVPN the app and click on the cog (gear) icon to access the app settings. Click on “Connection.” Under “VPN protocol,” select “OpenVPN (UDP)” or “OpenVPN (TCP)” from the drop-down menu.
What is the best protocol for NordVPN? ›
What encryption protocol does NordVPN use? NordVPN uses the OpenVPN protocol, which is well known for its security and reliability. Since 2020, users have also been able to choose NordLynx, which is built around the WireGuard® protocol. It provides high-speed connection while also maintaining top-notch security.
What is the most advanced VPN protocol? ›
IKEv2 – Internet Key Exchange
Based on the IPSec framework, IKEv2 is the most recent and advanced VPN protocol.
Which VPN protocol is best UDP or TCP? ›
UDP (user datagram protocol)
The advantage is that UDP is much faster than TCP, especially over long distances, and is also more data-efficient. The downside is that if the receiver is overwhelmed or if there is an outage, the data will simply be lost.
Which protocol is better, TCP or UDP? ›
TCP is best used for direct communication in which a reliable connection is needed, such as web browsing, email, text messaging, and file transfers. UDP is best used for live and real-time data transmission when speed is more important than reliability.
Is NordLynx better than OpenVPN? ›
NordLynx is much faster than OpenVPN and other VPN protocols, making it a clear upgrade for everyday security. In fact, NordLynx's speed test results are among the highest of all commercial VPNs. To use NordLynx with the NordVPN app for your device, follow the tutorial for your OS below.
What NordVPN plan is best? ›
So, if you only need a high-quality VPN without any additional functions, the Basic plan is the most pocket-friendly option. But if you want Threat Protection and a password manager, the Plus plan has the best value.
