Which VPN tunneling protocol provides the best features for mobile users?

1. PPTP

2. SSTP

3. IKEv2

4. L2TP

The correct answer is: IKEv2

Choosing the right VPN tunneling protocol for mobile users is crucial for ensuring performance, security, and connectivity. IKEv2 (Internet Key Exchange version 2) is particularly well-suited for mobile environments due to several key features. One of the standout qualities of IKEv2 is its ability to quickly re-establish the connection when a mobile device switches between networks, such as moving from Wi-Fi to cellular data. This capability is known as “mobility” support and is particularly advantageous for users who frequently move between different network environments. Additionally, IKEv2 operates using strong encryption methods and is less susceptible to security vulnerabilities compared to some older protocols. It also offers support for more advanced authentication methods, ensuring that data remains secure while in transit. This combination of fast reconnections, robust security, and support for modern authentication techniques makes IKEv2 the preferred choice for mobile users who require a reliable and secure connection. Contrarily, PPTP is known for its speed but lacks strong security features, while SSTP and L2TP both have their own advantages but may not offer the same level of seamless transition between networks as IKEv2 does. SSTP, while secure, is a proprietary protocol tied closely to Windows environments,
