If you’ve been VPN shopping for a while, you probably know about the basic encryption and spoofing features–but don’t ignore advanced functions like an automatic kill switch. Today, we’ll review the best VPNs that include kill switches, plus show you how a kill switch works and why it’s useful.
One extremely useful but often overlooked feature of a VPN is a kill switch. This is a function which ensures that you will never accidentally send data over an unsecured internet connection. If you are concerned about security, and especially if you are downloading illegally (which we do NOT condone), then a kill switch is a key feature that you should be looking for when you choose a VPN provider.
Below we’ll explain to you more in depth about what a kill switch is. If you decide that it’s a feature which is important for you, after that we’ll have recommendations for the best VPNs with a kill switch so you can choose one which meets your needs.
Intro to kill switches – What you need to know
You might see a kill switch referred to as an internet kill switch, a VPN kill switch, or a network lock. These are all different terms for the same thing, which is a feature of your VPN software. The idea is that the switch can be enabled or disabled as you require. When the switch is activated, no data will be sent over your internet connection unless the VPN is enabled. When the switch is turned off, your internet connection can be used normally whether the VPN is connected or not.
Why would you want to use a kill switch? Well, it’s an important feature if you’re extremely concerned about your privacy and you want to make sure that no data is ever send unencrypted over your connection. This is particularly vital if you’re going to be downloading files using torrents or other peer to peer systems, as even accidentally downloading a small portion of a file over an unsecured connection can still get you in legal trouble.

If you’re wondering how you could accidentally use an unsecured connection, it can be easier than you think to make that mistake. When you’re connected to a VPN server, after several hours the server might go down and you would have to connect to a new server. In the few seconds between disconnecting from the old server and connecting to the new one, you could send data over the internet without even realising it. Or when you turn your computer on, you could forget to start up your VPN software before opening your web browser, and then your currently open tabs would be downloaded over the unsecured network.
With a kill switch enabled, you can be sure: you’ll never inadvertently send data over an unsecured connection. And here’s another useful tip – companies which offer a kill switch in their VPN software are the companies which are most concerned with privacy. So if you want to keep your internet use private and you see that your VPN has a kill switch option, that’s a good sign.

It can be a lot of work to compare all the different VPNs on the market, which is why we’ve gone to the trouble for you. Our extensive testing and research has returned the following VPNs as having the best performance, privacy, and of course–automatic kill switches:

VyprVPN not only has a kill switch for Mac and Windows, but also has detailed settings to let you customise it to your liking. You can see the settings for the kill switch by going to the Settings section of your software, then clicking to the Connection tab. At the top of this page you’ll see a section labelled Kill Switch.

To access the internet, you’ll have to open up the software and connect to a VPN server first. You must choose one of these two options to activate the kill switch.
There’s also a third option below, which allows you to block LAN traffic as well as internet traffic. To enable this, check the box next to where it says Stop LAN traffic when Kill Switch is active.
