What is a VPN Kill Switch & How Does it Work?

A VPN kill switch, also known as an internet kill switch, is like a fail-safe device that deploys if your VPN connection drops. What it does is that it instantly stops you from connecting to the internet when you disconnect from the VPN. This prevents third parties or any outsider from identifying your true IP address and location.

Once your VPN service is back up and running, it automatically reconnects your device to the internet. So, how does an internet kill switch work?

A VPN with an internet kill switch constantly monitors your internet connection. It looks for any signs of change, such as a drop-in connection or changing the IP address. A kill switch instantly kicks in when it detects such change and halts your internet connection.

Primary causes for frequent disconnections

Unfortunately, frequent VPN disconnections may spoil your fun a great if you cannot access your desired geo-restricted content. Therefore, you should perform some tweaks to overcome VPN disconnection issues timely.

Here is the list of major reasons that do not allow your VPN services to work properly:

  • VPN protocol selection
  • Network congestion/ poor signal strength
  • Firewall or router settings

VPN protocol selection

Surprisingly, connections seamlessly perform when the network uses the TCP protocol compared to the default UDP protocol. If your connection is unstable, there is no harm in switching the protocol.

Network congestion / poor signal strength

When numerous people use the same Wi-Fi connection to access the internet, the strength of Wi-Fi connections may decrease to a certain degree. The same goes for VPNs as well. This is because the strength of Wi-Fi connections also influences the performance of VPN services a great deal.

This is the reason VPN connections are disconnected quite often.

Firewall or router settings

At times, firewall or antivirus software may hamper the VPN connection speeds considerably. Therefore, you should disable these features to check the performance of your VPN service. If your VPN connections become stable once you have disabled the security features, you should not apply these settings on your VPN services.

What is the purpose of a VPN kill switch?

The first and foremost objective of using a network lock feature is to deliver a next-level additional layer of security to users. When you browse the internet through a VPN, the role of the above said benefits becomes crucial.

You can easily filter all VPNs that provide kill switch features by visiting the VPN reviews guide. In addition, you can go through this VPN comparison chart that explains which VPNs offer a kill switch feature.

Types of network lock or kill switch?

Surprisingly, the network lock or kill switch has two types. You may consider these types like active kill switch and passive kill switch. An active kill switch does not send your traffic to unsafe networks. When your VPN provider suddenly stops working, you have disconnected from the internet automatically.

What makes a passive kill switch more effective than its counterpart is its next-level security feature. It means a VPN app does not send your internet traffic as soon as it stops receiving a signal from the VPN server.

How do I know if my VPN has a built-in kill switch?

At times, it becomes difficult for newbies to explore network lock features in their VPN software. This is because every VPN service has mentioned kill switch by its own name. Upon digging deep, you can find the said privacy advantage appropriately.

You might be wondering how you can find an internet kill switch hassle-free. In case you are using PureVPN, you can click on advanced options. To find advanced options, you will need to press the menu tab first. Here is the snapshot of the feature:


This way, you can find out your desired privacy benefit accordingly. If you are using VPN services other than PureVPN, you may read the FAQs section provided on official sites.

How can I enable a VPN kill switch?

The task of enabling a kill switch is simple and does not any rocket science. Here is how you can do:

  • Launch NordVPN Windows app and go to settings>general

  • In case you opt app kill switch, you will not be able to use the internet when the VPN connection drops


This is how you can activate NordVPN kill switch feature on your Windows devices stress-free.

Are kill switches activated by default?

It depends on your VPN service, as different services do not activate the feature by default. You will need to use the app settings first. Once you have opened the app settings, you can enable the privacy advantage accordingly.


The above screenshot demonstrates that Surfshark users will have to activate kill switch benefits from the app settings first. This way, they can secure their internet traffic hassle-free.

Third-party Kill switches

Interestingly, you are free to use other third-party resources like VPNetMon and VPN watcher. VPNetMon allows you to secure your internet connection when your VPN provider suddenly stops working. The said protection tool does not turn off the internet completely.

In fact, it just shuts down the pre-selected program that may expose your IP addresses while using an insecure internet connection. As for VPN watcher, we will describe it in the next heading.

Still using a VPN service with no network lock?

Reddit opinions about Internet Kill Switch VPNs

Reddit is one of the most sought communities that offer unbiased and updated information about numerous niches instantly.

Here we can see Reddit user “skeleton_tree” responding to a question sharing their own experience with NordVPN Kill Switch. The reddit user confirms that he has been using NordVPN for several years now, and the kill switch feature seems to work fine. He further adds that users using a windows operating system can use the NordVPN’s kill switch on windows feature called “app kill switch feature,” – which will shut down the torrent client app in case of any VPN disconnection. This feature easily adds an extra layer of security and precaution.


In the following Reddit comment, we can see Reddit users “iarehman” and “FunRoof” confirming that the Kill Switch feature comes built-in with Surfshark and PureVPN both. Reddit user “FunRoof” further goes on and confirms that Surfshark Kill Switch works.


We also happen to saw a question posted by Reddit user “michaeljc70” regarding a torrent client that wouldn’t upload/download if the VPN isn’t enabled?. One possible solution could be using a BT client and binding it to a specific network interface. If you bind to the IP number of OpenVPN’s TUN0 device, then all the BT client traffic will only pass through that interface. Since the IP is not static, you’d have to keep updating the client settings again and again.



So now that you know all about kill switch and VPN providers offer this feature, let’s go through some of the most frequently asked questions about VPN kill-switch.

Does VPN stay on all the time?

Generally yes; however, you will need to reconnect to a VPN server once you restart your computer or your smartphone. To always keep your VPN running, you can configure a VPN directly onto your router.

What happens if VPN disconnects?

Well, it all depends on what you’re using a VPN for. For instance, if you’re using a VPN to download torrents and your VPN disconnects, you can end up being questioned by your ISP or even by law enforcement agencies depending on the severity of the matter.

Is there any free VPN with Kill Switch?

Most free VPNs don’t offer the kill switch feature in their free plans, as it is only available in their premium plans. And free VPNs that do offer kill switch come with limited functionality. Therefore, we recommend using one of the VPNs mentioned above that offer the best kill switch features for maximum security.

Some of the free VPNs offering kill switch are Hotspot Shield, Speedify, and TunnelBear.
