Over 2,000 servers in 90+ countries, fast performance, and strong 256-bit AES encryption are just some of the features that make ExpressVPN one of the better Virtual Private Network (VPN) providers around. Add fair pricing and tight security features such as a kill switch into the mix and you get quite a deal.  

A kill switch is a VPN feature that helps you protect your sensitive data in case your VPN connection is interrupted.

ExpressVPN’s kill switch is called Network Lock and it is currently available for Windows, Mac, and Linux.

The purpose of Network Lock is to prevent your network traffic from flowing outside the encrypted VPN tunnel. Therefore it safeguards your data against becoming exposed to unwanted parties if your VPN connection drops, thus preserving your anonymity and security on the Internet.

When Network Lock is enabled, you will only be able to access the internet when you are connected to the VPN. If your VPN connection suddenly breaks, Network Lock is there to block all internet access so that your data is kept safe.

This step-by-step guide will show you how to activate and deactivate a kill switch in your ExpressVPN Windows app.
