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.

These are the most secure VPNs with that essential kill switch feature:

  1. NordVPN Best VPN with Kill Switch – While many VPNs offer kill switch functionality, NordVPN offers so much more. Thousands of servers, specialty connections, powerful encryption.
  2. Surfshark – Kill switch plus advanced leak protections ensure not even a single byte escapes unencrypted.
  3. ExpressVPN – Fast, stable network that keeps the kill switch a redundant precaution, rather than a constant necessity.
  4. PureVPN – One of the best-stocked cybersecurity toolboxes available. Most often used to break China’s Great Firewall.
  5. IPVanish – The torrenter’s delight; powerful encryption plus automatic cutout keeps your activity hidden.
  6. VyprVPN – Secure connections to a privately owned and operated network allow for true anonymity.

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.

Top recommended VPNs with a kill switch

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:

1. NordVPN

NordVPN - Editors choice

NordVPN helpfully provides a kill switch option in both its desktop software and its mobile apps. The desktop version, for Windows and Mac, can shut down applications which you specify if your VPN connection goes down. The mobile version for Android and iOS disables internet access across the system if the VPN connection goes down, meaning that apps won’t be shut down but they won’t be able to communicate across the unsecured internet.

To enable the kill switch on the desktop software, open it up and click on Settings at the top, and then to General on the left. This will show you a number of options, including the Kill Switch slider. You can toggle the slider to turn the kill switch on and off. And below the slider you can add applications which should be terminated in the case of VPN disconnection – such as your web browser and your torrent client.

To enable the kill switch in the mobile app, open the app and click on the Account icon in the top left. You’ll see a Kill Switch option which you can toggle on and off.

NordVPN is a highly security-minded VPN provider, and in addition to the kill switch they have extra strong double encryption which keeps your data as safe as possible by encrypting your metadata as well as the data itself.

The software can be installed on many operating systems, like Windows XP, Windows Vista, and Windows 7, 8, and 10 as well as Mac OS, Linux, iOS, Chrome OS, Android, and Windows Phone. So it should be no problem to protect all of your devices with this one subscription.

  1. well well, Express VPN again. They must really have good marketers. I monitored several cases of protection drops/leaks last year and in each case their “technical support” told me nope no problem at all. Then this year received a notice from the local ISP that yes they could track my traffic and provided proof. This service is false security. Their ap development has stalled and is far behind the newer security threats. DO NOT TRUST EXPRESS VPN.
