What is IKEv2?

IKEv2 (Internet Key Exchange Version 2) or IKEv2 / IPsec is one of the VPN protocols with a key strength in speed. It is suitable for all devices and can be used on all platforms. IKEv2 cannot be used without IPsec encryption, but it is generally referred to simply as IKEv2.

The features are considered more stable than OpenVPN and can be customized to suit the usage.

How does IKEv2 work?

IKEv2 creates and manages Security Associations (SA) between the devices we use and the VPN server to ensure authenticity, security, and IPsec encryption, which handles encryption, decryption, and data transmission.

How good is IKEv2?

IKEv2 is renowned for its speed and reliability, whether used through any provider such as Wi-Fi or cellular, ensuring smooth operation. It features strong AES-256 encryption with SHA2-384 to enhance integrity and security. Additionally, it supports Perfect Forward Secrecy (PFS) with a 3072-bit Diffie-Hellman key to effectively protect user data.

Which is better, IPsec or IKEv2?

IPsec and IKEv2 are often used together to maximize the benefits from their combined strengths in a VPN. IPsec performs well in terms of secure and reliable data transmission and user safety, while IKEv2 enhances this with greater stability, faster data transfer, and smoother network switching. Therefore, VPN providers prefer IKEv2/IPsec as the protocol they offer.

Benefits of VPN

1. Helps save costs. Creating a virtual network has only the main cost of Internet service, and from those who have used it, it has been found that costs can be reduced by up to 40%.

2. There is data security because VPN encrypts data. Only the intended recipient can decrypt and understand the code to use it. Users can also enhance security further, such as with Firewall systems and Encryption systems, etc.

3. Highly flexible, because even though the data is encrypted, if the user permits or in cases where external parties need to access the information, the user can also allow others to view their data.

4. It is efficient in data transmission because it operates on a public network. Therefore, the VPN system is capable of transmitting data quickly.
