VPN Protocols Explained: Which One Should You Use?

1. OpenVPN

Overview: OpenVPN is an open-source protocol known for its strong security and versatility. It can run on any port, which helps it bypass firewalls and network restrictions.


  • Strong encryption and security
  • Highly configurable
  • Works on most platforms
  • Good for bypassing firewalls


  • Requires third-party software
  • Slightly more complex to set up

Best For:

  • Users seeking the highest security and privacy
  • Bypassing network restrictions and firewalls
  • General-purpose use on various devices

2. IPsec/IKEv2

Overview: IKEv2 (Internet Key Exchange version 2) combined with IPsec (Internet Protocol Security) is a highly secure protocol, especially well-suited for mobile devices. It’s known for its speed and stability.


  • Fast and secure
  • Excellent for mobile devices
  • Supports multiple encryption algorithms
  • Stable connection, even when switching networks


  • Not as widely supported as OpenVPN
  • Can be blocked by some firewalls

Best For:

  • Mobile users who need a stable and fast connection
  • Environments with changing networks (e.g., switching between Wi-Fi and mobile data)

3. WireGuard

Overview: WireGuard is a newer protocol designed to be faster and simpler than its predecessors. It aims to provide high security with significantly fewer lines of code.


  • Extremely fast and efficient
  • Easier to audit due to its simplicity
  • High security


  • Still relatively new and not as widely supported
  • Limited configuration options compared to OpenVPN

Best For:

  • Users seeking the fastest possible VPN speeds
  • Secure and efficient use on modern devices
  • Future-proofing, as it gains wider adoption

4. L2TP/IPsec

Overview: L2TP (Layer 2 Tunneling Protocol) combined with IPsec provides strong encryption and is supported on most operating systems. However, it can be slower due to double encapsulation.


  • Widely supported on many devices
  • Strong encryption with IPsec


  • Slower speeds due to double encapsulation
  • Can be blocked by some firewalls

Best For:

  • Users who need a balance between security and compatibility
  • Devices and operating systems with native support for L2TP/IPsec


Overview: PPTP (Point-to-Point Tunneling Protocol) is one of the oldest VPN protocols. It’s known for its speed but has significant security vulnerabilities.


  • Very fast due to low encryption overhead
  • Easy to set up


  • Weak security; easily compromised
  • Not suitable for sensitive data

Best For:

  • Situations where speed is more important than security
  • Streaming geo-restricted content where encryption isn’t a primary concern


Overview: SSTP (Secure Socket Tunneling Protocol) is a Microsoft-developed protocol that integrates well with Windows. It’s known for its ability to bypass most firewalls.


  • Good integration with Windows
  • Can bypass firewalls effectively
  • Decent security


  • Limited support outside Windows
  • Developed by Microsoft, raising concerns for those wary of proprietary protocols

Best For:

  • Windows users who need to bypass firewalls
  • Users looking for a secure and straightforward setup on Windows

Which One Should You Use?

For Maximum Security and Privacy:

  • OpenVPN: Ideal for users who prioritize security and flexibility. It’s highly configurable and widely supported, making it a top choice for privacy-focused users.

For Fast and Stable Mobile Connections:

  • IKEv2/IPsec: Excellent for mobile devices due to its speed and ability to maintain a stable connection when switching networks.

For Speed and Simplicity:

  • WireGuard: Best for users looking for fast and efficient VPN connections with strong security. It’s suitable for general use and future-proofing as it gains more support.

For Compatibility Across Devices:

  • L2TP/IPsec: Suitable for users who need a good balance between security and compatibility, especially on older devices or operating systems.

For Fast Streaming with Lower Security Needs:

  • PPTP: While not recommended for secure communications, PPTP can be useful for quickly accessing geo-restricted streaming content.

For Windows-Centric Users:

  • SSTP: Ideal for Windows users needing to bypass firewalls while maintaining a decent level of security.
