What is a VPN Kill Switch?

So, what exactly is a VPN kill switch? It is an important security feature designed just to shield what you do on the internet. Even when your connection unexpectedly drops. Think of it as an emergency brake for your internet connection. When we first discovered this feature we were quite amazed to see how it increases our online security.

If it detects any interruption or failure in the virtual private network service it immediately goes into action. The kill switch for VPN instantly cuts off all internet traffic to make sure that none of your data is exposed because of an unsecured connection.

We have also experienced those heart-stopping moments when our virtual private network suddenly disconnected while we were browsing. Without this feature, our real IP address and online activities could have been exposed. That is why we always recommend using a virtual private network that offers this amazing feature.

How Does a VPN Kill Switch Work?

Let us break it down. The whole process of how a VPN kill switch actually operates. Basically it:

• Monitoring the VPN Connection: It is always on high alert to watch your virtual private network connection. It is just like having a security guard that never sleeps.
• Detecting a Connection Drop: Your VPN connection can drop for any reason. Maybe your internet was hiccupped, or the server had a moment. The kill switch immediately detects these changes.
• Triggering the Kill Switch: The moment a disconnection is detected this feature springs into action faster than you can say “privacy breach!”.
• Blocking Internet Traffic: Internet traffic is immediately stopped, and that prevents any data from being sent outside the secure tunnel of the virtual private network. It is like slamming the castle gates shut when you spot the enemy coming toward you.
• Maintaining the Block: It keeps your internet blocked until the VPN connection is restored. No data leaks on its watch.
• Restoring Internet Access: Once the VPN is back online it allows internet traffic to flow again but only through the secure tunnel. Just like reopening the gates once you are sure that the coast is clear.

We have seen this process in action many times and it is truly impressive how quickly and effectively the VPN kill switch works to protect your online data.

Types of VPN Kill Switches

Not all VPN kill switches are created equally. There are two main types. Each has its own strengths:

System-level Kill Switch 

This is the big boy of kill switches. It stops all internet access for your entire device when there is a drop in connection. This is very helpful in ensuring total protection. It is like cutting the power to your whole house to make sure no one can peek through from any window.

Application-level Kill Switch

This is the more selective approach. It allows you to choose specific applications that will be blocked if the virtual private network disconnects. We often use this when we need certain apps to remain connected while protecting our most sensitive activities. It is like having individual breakers for each room in your house.

The uses of each type vary and the ideal selection is based on your unique needs. We have found that having both options available to you gives even more flexibility to change your security to different situations. 

Did you know?

You can implement a kill switch at the router level in order to protect all of your devices at home or at work. This makes sure that if the VPN connection drops, all of the devices on the network are immediately protected.
