ExpressVPN is a Virtual Private Network (VPN) service that prides itself with cutting-edge technologies such as 256-bit AES encryption, DNS/IPv6 leak protection, and split-tunneling, a feature that lets you route some of your device or app traffic through the VPN while other devices or apps maintain direct access to the internet. 

As ever, security is at the forefront of any VPN service and with ExpressVPN, you can choose between OpenVPN (UDP or TCP), L2TP/IPSec, PPTP, and SSTP security protocols.

  • OpenVPN UDP (‘User Datagram Protocol’) is mostly used for streaming media. It is the best combination of security and speed, but it may not work on all networks.
  • OpenVPN TCP (‘Transport Control Protocol’) is a bit slower than UDP, but it is likely to function on all types of networks. It is used for transferring most types of data such as files and websites and is ideal for media streaming.
  • L2TP/IPSec or L2TP over IPSec is a combination of two protocols - L2TP (‘Layer 2 Tunneling Protocol’) and IPSec (‘Internet Protocol Security’). This protocol combination comes with a pre-shared key and only a subset of VPN locations might be available for it.
  • PPTP (‘Point-to-Point Tunneling Protocol’) is the least secure among the options offered and you should only use it if you have a specific reason for it. Just like with L2TP/IPSec, only a subset of VPN locations might be available for it.
  • SSTP (‘Secure Socket Tunneling Protocol’) runs over TCP port 443 and is likely to work on most networks. Like with the previous two, only a subset of locations might be available for SSTP.

This step-by-step guide will show you how to choose protocols in your ExpressVPN Windows app. Using ExpressVPN is the best way to defend yourself against hackers, government spies, data resellers, and identity thieves
