VPNFast offers three protocol options: IKEv2, WireGuard, and Shadowsocks. Selecting the best protocol depends on your priorities:

  • IKEv2 (Balance): This reliable protocol offers a good balance between speed and security, making it suitable for everyday VPN use.
  • WireGuard (Speed): Known for its efficiency, WireGuard is a fast and lightweight protocol ideal for prioritizing speed without sacrificing strong security. 
  • Shadowsocks (Privacy and Bypassing Restrictions): Designed to bypass internet censorship and enhance privacy, Shadowsocks is a good choice if you need to access restricted content or are in a region with heavy internet restrictions.


Finding the Optimal Protocol:

  • Consider testing different protocols to see which one delivers the best performance on your specific device and network configuration. 


Additional Notes:

  • VPNFast might not explicitly state which protocol is the default option. Explore the app's settings to see the currently selected protocol and choose the one that best suits your needs.
  • Some advanced users might have preferences based on specific technical aspects of each protocol. Research each protocol further if you have in-depth knowledge and specific requirements.
