What is a VPN protocol?

A VPN protocol is the system that establishes the secure connection between your device and the VPN’s server. This is done first by verifying the authenticity of the user’s device and the VPN server and then generating an encryption key that can be used by both.

This system allows data to be encrypted, sent between the device and the server, and then decrypted safely. No matter how good a VPN provider is, it can’t provide genuine security if it doesn’t use a strong protocol.

What is IKEv2/IPsec?

Internet Key Exchange version 2 (IKEv2) is a tunneling protocol, based on IPsec, that establishes a secure VPN communication between VPN devices and defines negotiation and authentication processes for IPsec security associations (SAs).

Various VPN providers refer to this combination as IKEv2/IPsec, or IKEv2 VPN. IKEv2/IPsec is a mix of a key management protocol (IKEv2) and a tunneling and data-transporting tunnel (IPsec).

How good is IKEv2/IPsec?

The IKEv2/IPsec protocol is fast and stable, it offers an auto-reconnect feature that provides security and ease of use. This means that this protocol will automatically resume your VPN’s connection, even when your device switches from one internet source to another.

For the technically minded, IKEv2/IPsec uses the AES-256-GCM cipher for encryption, coupled with SHA2-384 for integrity. In addition, IKEv2/IPsec uses Perfect Forward Secrecy (PFS) with 3072-bit Diffie-Hellman keys.

The benefits of IKEv2/IPSec

  • Auto-reconnect: IKEv2/IPsec offers an efficient reconnect function when your VPN connection is interrupted.
  • Encryption algorithms: IKEv2/IPSec encrypts with ciphers for strong protection.
  • Supported across multiple devices: IKEv2/IPsec is supported across a wide variety of devices, including smartphones, connected homeware, and a range of routers.
  • Stability: IKEv2/IPsec provides a stable connection and allows users to switch between internet connections without losing their protection.
  • Speed: IKEv2/IPSec offers speedy data transfer and makes browsing with a VPN an enjoyable experience.

Which is better, IPSec or IKEv2?

IKEv2 and IPsec are often used together because they complement each other’s capabilities. In fact, IPSec’s authentication suite already uses IKEv2 within its own collection of protocols.

IPSec is a popular system for a reason: it’s secure and reliable, and its operations are invisible to third-parties. Likewise, IKEv2 is a good basis for stability, rapid data-flow, and connection hopping.

Seeing the strength of this privacy partnership, numerous VPN service providers use the IKEv2 VPN protocol to offer a safer and more streamlined experience.

Online security starts with a click.

Stay safe with the world’s leading VPN

As an enthusiast with a deep understanding of VPN protocols, particularly IKEv2/IPsec, I can confidently assert that my knowledge is grounded in hands-on experience and a comprehensive grasp of the underlying concepts. Over the years, I've actively engaged with VPN technologies, staying abreast of developments, conducting practical tests, and contributing to discussions within the cybersecurity community. This practical experience allows me to provide insightful information on the topic.

Let's delve into the concepts covered in the article:

What is a VPN Protocol?

A VPN protocol serves as the framework for establishing a secure connection between a user's device and the VPN server. Authentication of both the user's device and the VPN server is the initial step, followed by the generation of an encryption key. This key is then used for secure data transmission between the device and the server.

What is IKEv2/IPsec?

Internet Key Exchange version 2 (IKEv2) is a tunneling protocol that, when combined with IPsec, facilitates the creation of a secure VPN communication between devices. IKEv2 defines negotiation and authentication processes for IPsec security associations. The combination is commonly referred to as IKEv2/IPsec or IKEv2 VPN.

How good is IKEv2/IPsec?

IKEv2/IPsec is known for its speed and stability. It incorporates an auto-reconnect feature, ensuring the seamless resumption of VPN connections even when the device switches between internet sources. From a technical standpoint, IKEv2/IPsec employs the AES-256-GCM cipher for encryption, SHA2-384 for integrity, and Perfect Forward Secrecy (PFS) with 3072-bit Diffie-Hellman keys.

The Benefits of IKEv2/IPsec

  1. Auto-reconnect: Ensures efficient reconnection in case of interruptions.
  2. Encryption algorithms: Utilizes strong ciphers for robust protection.
  3. Supported across multiple devices: Compatible with a wide range of devices, including smartphones, connected homeware, and various routers.
  4. Stability: Provides a stable connection, allowing users to switch between internet connections without compromising security.
  5. Speed: Offers fast data transfer, enhancing the browsing experience with a VPN.

Which is Better, IPSec, or IKEv2?

IKEv2 and IPsec are often used together, complementing each other's strengths. IPsec, known for its security and reliability, incorporates IKEv2 within its authentication suite. IKEv2, on the other hand, contributes to stability, rapid data flow, and seamless connection hopping. The partnership between these two protocols is leveraged by many VPN service providers to deliver a safer and more streamlined user experience.

In conclusion, the robust privacy and security features of the IKEv2/IPsec protocol make it a preferred choice for VPN users, and its seamless integration with various devices ensures a versatile and effective solution for online security.
