A VPN kill switch is a tool that terminates the internet connection on your computer, phone, or tablet in the case when your VPN connection is broken.
This means that there are no opportunities for your IP address and other information could be unveiled if the VPN not work, thanks to the VPN kill switch.
In this way, the security and anonymity of your connection to the Internet will not be violated. The VPN kill switch feature is usually turned on in most VPNs, but you can easily turn it off if you wish to.
If you turn it off, you can browse the Internet as you normally would even if your VPN connection is not active. But if you switch it on, you cannot transmit any data over the internet connection if your VPN is disconnected.
When you consider the maximum protection you can employ on your VPN service, then a VPN kill switch will be impactful for complete security. However, not all the VPNs in the market have this feature, or if they do, it is not an effective one.
How Does A VPN Kill Switch Work?
A VPN (Virtual Private Network) kill switch is a crucial addition to any VPN to boost its security aspects.
But what is a VPN kill switch, and why is it so important? It also has a security feature of keeping your data safe even in the instance that the VPN connection is lost abruptly.
Here is a breakdown of how a VPN kill switch operates, the types of VPN kill switch, and why it is crucial.
Continuous Monitoring
The kill switch works in the background and actively checks your connection to the VPN. It manages the status of the VPN tunnel, verifying if the connection to the tunnel is intact or not, ensuring the security features of VPN are fully operational.
Connection Detection
The kill switch for VPN is programmed to detect various types of connection failures, such as:
- Dropped Connections: When disconnects from the VPN server are experienced.
- Network Changes: For instance, this is the case when you change from using Wi-Fi to mobile data or from mobile data to Wi-Fi.
- IP Address Changes: Any change in the IP address that shows the inability of the user to continue using the VPN connection.
Immediate Response
Once it identifies a connection problem, the kill switch goes into operation at once.
It minimizes the exposure of your internet data to other networks since it prohibits any information from passing through your device to the internet or the other way around except through the VPN tunnel.
This is paramount so that the identity of the person writing the article is not disclosed or the author is not easily identifiable.
Restoration of Connection
When the VPN connection is back, the kill switch disables your internet connection again and returns your access to work.
Newer kill switches can go further to the extent of actually giving you some form of control over the parameters that indicate when the connection should go back online.
- Lightning-fast speeds to browse without lag
- Servers in 105+ countries around the globe
- Military-grade security to stay safe online
- Try it risk-free with its money-back guarantee
- Native apps for all major devices
When Does A VPN Kill Switch Activate?
A VPN also has a feature referred to as the VPN kill switch that works at certain conditions to shut down the internet connection. Here are the key scenarios when a VPN kill switch typically engages:
VPN Connection Loss
The main reason to activate a kill switch is the disruption of the VPN connection as such. This can be occasioned by one reason or the other like: server problems or even fluctuations in the network.
Switching VPN Servers
If you switch from one VPN server to the other manually then the connection may be severed momentarily. To prevent any leakage during the transition, there will be a kill switch which will be activated during this time.
Internet Disconnection
In case the internet connection is severed (for instance owing to Wi-Fi problems), the kill switch will activate to prevent any sensitive data from being sent.
Device Restart or Updates
If for instance your device restarts or updates an application that reconnects to the internet and the VPN is not active, then the kill switch will suspend internet connectivity until the VPN is on.
Firewall Interference
Sometimes, a new firewall is placed, and it may not allow a VPN connection to be established. As for the kill switch, if it identifies that the VPN is being plugged, then it will turn on to avoid usage of unsecured Internet connection.
User Actions
When a different user is utilizing your device and, perhaps, turns off the VPN, the kill switch will come into play and ensure the protection of your actions.
Types Of VPN Kill Switches
There are two main types of VPN kill switches:
System-Level Kill Switch
- Closes down every connection on your device to the internet off the VPN connection is lost
- Global Policy: Prevents data transmission outside the protected area of the VPN connection
- Offers end-to-end safe end-to-end leakage of data
- It is suitable for relatively informative uses where the user values the maximum possible protection.
Application-Level Kill Switch
- Enables you to choose the applications that you want to be blocked whenever the VPN connection is lost
- Lets other apps remain free to connect to the Internet
- Is more flexible than the system switch
- For users who require constant internet connection for non-sensitive applications, but at the same time want to protect other applications.
The system-level kill switch is preferred notably due to its high level of security as it ensures that every transmitted data is encrypted and secure.
Still, the application-level kill switch is useful for people, who would like to have more granularity in which applications are shut down when the VPN connection drops.
While most VPNs offer the basic application-level kill switch, some VPNs such as NordVPN provide both types while others such as ExpressVPN have a strict system-level on-office thus giving the user optimal protection.
In the end, the choice is down to the user depending on the security needs and preferences of the user when considering the types of kill switches available.
Why Should You Use A VPN Kill Switch?

4. Security provision in social networks
Public Wi-Fi connections are typically unsecured and pave the way for several cybercrimes.
A VPN kill switch is most necessary when using public connections because it will disconnect the device from the internet if the VPN connection is severed, thereby protecting the device from MITM and other forms of attacks.
5. Prevention of Unintentional Monitoring
However, in countries with strict control over internet connection such as Egypt and China, a kill switch can be of great importance.
It guarantees that after some time your connection does not remain unprotected and thus attracts the attention of authorities or hacker groups.
6. Peace of Mind
Having VPN assurance that the internet will be disconnected automatically when the VPN drops offers security. This enables the users to explore listening and interacting despite so many privacy issues.
7. Legal and compliance risks
For companies, having a VPN with a kill switch feature means that companies do not violate any data protection laws.
They reduce the potential of sharing with unauthorized persons and also assist in preserving the credibility of company information.

How Do You Test A VPN Kill Switch?
To test a VPN kill switch effectively, follow these detailed steps based on the provided search results:
Check Your Internet Connection
Before engaging in the test, confirm that all your normal Internet connection is in order. To obtain this information, you should switch from the VPN connection and visit some websites
Connect to Your VPN
Open your VPN software, and log on to a server. The kill switch feature should be activated and can be done in settings if it is not enabled by default.
Verify Your IP Address
One way to check for this is to use an IP checker and verify that your internet traffic is flowing through the VPN server. This step checks that your VPN is on and your IP address is concealed.
Simulate a VPN Disconnection
You can simulate a VPN failure in several ways:
- Manual Disconnection: It is advisable to use a VPN application to disconnect the VPN server from the last source.
- Network Disruption: If you are working on a device, then switch on airplane mode or, better still, turn off the internet connection for some time.
- Firewall Block: Connect to the internet and go to your PC’s firewall settings that will help you in blocking the VPN application but you can go on with your business.
Observe Internet Access
After plunging into the simulation, make sure the network is off or that your Internet connection is unavailable. If the kill switch is working as required, you should find that you are disconnected from the internet as soon as you flick the switch.
To ensure its proper utilization, an AMT must be employed.
For some more automated handling, you can use a tool which is called Page Refresher. Set it to refresh a URL that shows your IP address. Start the refresh before connecting to your VPN, then observe the IP address displayed:
- Before VPN Connection: Log your real IP address.
- After VPN Connection: Make sure that the IP address is the same as on the specific VPN server.
- During Disconnection: There should be a ‘no internet’ notification or it should change to the original IP when using the kill switch during the simulation of a disconnect.
Check for Data Leaks
After using the kill switch function, return to the internet and conduct an IP or DNS leak test to confirm that there were no leaks during the kill switch test. This will help in confirming the status of your data when the VPN connection was off, and that it was still secure.
