Its code is closed-source, meaning it is not publicly available. It has privacy doubts due to its creators (Microsoft mostly). Let’s review the biggest advantages and disadvantages of this protocol. Generally, IKEv2 is a secure and fast protocol many users love using. If a VPN provider offers it, choose a different option. You should also avoid L2TP and PPTP protocols. IKEv2 supports Mobility and Multi-Homing protocol (MOBIKE), making connections from one Wi-Fi to another smoother.Ĭurrently, IKEv1 is obsolete, and a VPN should not use it as its tunneling protocol.It also uses less bandwidth since it needs fewer procedures of Security Association with the server.IKEv2 is much faster thanks to Network Address Translation-Traversal (NAT-T).Its developers have incorporated enhanced security measures and performance improvements. IKEv2/IPSec also uses Perfect Forward Secrecy ( PFS) to guarantee the security of derived session keys.IKEv2 uses UDP port 500, which could make it easier to block VPN connections.IKEv2 generates encryption keys for data (traffic) encryption and decryption.It also settles on the security measures used between these two peers.IKEv2 authenticates and establishes a secure connection between VPN clients and VPN servers.We can establish a more detailed guide on how IKEv2 VPN works. Devices natively support IKEv2, meaning there is no need for additional setup. IKEv2 works on most operating systems, including mobile devices like Android and iOS. A secure connection between the devices can occur after dealing with the Security Association.Essentially, IKEv2 VPN uses authentication methods to negotiate the security between the client and server.It sets up the Security Association, negotiating encryption keys operated by the VPN server and client.The purpose of IKEv2 is to perform the following functions: IPSec brings more security to the connection.So, users are less likely to experience sudden connectivity problems. IKEv2 benefits include bringing faster and more stable connections.Usually, you see a combination of IKEv2 and IPSec since IKEv2 nearly always uses IPSec: IKEv2 (Internet Key Exchange Version 2) is a protocol for bringing secure connections between VPN clients and VPN servers. Let’s see the benefits and disadvantages of IKEv2 VPN. However, how does it compare to other protocols like WireGuard® or OpenVPN? Whenever you use a VPN, you might notice IKEv2/IPSec is available as one of the protocols for setting up VPN connections. Microsoft and Cisco created the IKEv2 VPN protocol, a replacement for IKEv1. It deals with the Security Association (SA) meant to negotiate between devices initiating IPSec communication. It establishes a secure connection between VPN users and VPN servers. IKEv2 VPN is an application that uses IKEv2/IPSec tunneling protocol for transferring data.
