What is Kill Switch? 5 Best VPN With Kill Switch

Best VPN with Kill Switch

Kill switch is a feature that’s not being offered by all the VPNs but many popular VPNs had included it for security reasons.

Kill Switch in VPN is a special feature that automatically disconnects the internet connection on your device in case your VPN connection goes down due to certain reasons.

Having a VPN is really important for your internet privacy; however, a VPN without Kill Switch could lose its entire purpose of security.

Wondering how?

With a secure VPN, it’s virtually impossible for a data snooper to hack into a VPN server. So, they wait for your network to fail and that’s when they get into it. That’s why it’s necessary to have a VPN with a kill switch.

When you are connected to the internet but not to a VPN (in case of the VPN disconnect), your data will go unencrypted without you being aware. That scenario is certainly riskier than not having a VPN at all. Because when you are connected to a VPN, you might be carrying out highly sensitive internet activity or maybe viewing stuff that’s prohibited in your area thinking of yourself as being anonymous.

Why do You need to Have a Kill Switch?

When you are connected to a VPN, there are various personal details that are masked with the VPN encryption. Those details include;

  • Your IP addresses
  • Your browsing activity
  • Your location
  • Credentials you provide for online banking, online shopping, etc
  • Social account details

You think if you are connected to VPN, all your personal details are safe. And that’s true (if you are connected to a trustworthy VPN with a strict no-log policy and strong encryption).

But what if your data leaks with a VPN?

You might be thinking that how a VPN leaks data even if it has the strongest encryption and zero loopholes. Sometimes a VPN connection breaks due to certain reasons while your internet is connected. Therefore, the data goes unencrypted through your internet connection and your real IP address reveals.

That’s when a VPN kill switch comes into play.

As soon as your VPN connection shuts down, a VPN kill switch (if active) cuts off your internet connection too.

Reasons a VPN Connection Drops

There are various reasons why you can face a VPN connection drop.

Poor Internet Signals

WiFi or mobile internet connections are signal-based networks and if you are connected to such a device with inadequate signals, you may face VPN disconnection due to extreme data loss.

Highly Congested Network

When you are connected to public WiFi at a shop, airport, or maybe at your office, the highly crowded internet connection can disrupt your VPN connection.

Server Location

Sometimes a VPN server to which you are connected goes down. There could be many reasons for this. However, one of the most probable reasons is that you are connected to a server located far away from you. For instance, you are in Asia, and you are connected to a server in the US. Therefore, when not necessary, try to connect with the nearest server.

Switching Connection

Sometimes when you switch connections, for instance from WiFi to mobile data, you may face VPN connection drops or maybe go from one WiFi connection to another.

Heavy Software Running in the Background

There are times when heavy data requiring software disrupts your device’s connection to the VPN. it could be an app downloading a such update or might be windows itself.

VPN App Crash

Most VPN apps are troublesome while connecting and they might continue to have disturbances after connection. Therefore, you can face a VPN connection drop if the VPN app crashes or there is any issue with it.


If your system has an antivirus or firewall, it might be blocking a VPN to establish a VPN tunnel. You can fix this issue by adding your VPN to the firewall’s list of exceptions.

Best Kill Switch VPNs – Popular and Highly Secure

When you are connected to a VPN with a Kill switch enabled, you are surfing the internet without any kind of risk.

But, your VPN should be credible.

How Can You Make Your Own Kill Switch?

Yes, you can make your own kill switch with a firewall configuration. This firewall can only allow internet traffic while the VPN is connected. However, if you are not experienced with networking skills, you may easily pass on some loopholes and data leaks. Therefore, I don’t recommend you make your own kill switch. Instead, if you are paying for VPN then go for a VPN with a kill switch.

Also, there are some third-party apps such as VPNetMon, VPN Watcher, and VPN Lifeguard which work as a kill switch if your VPN doesn’t have this feature. But, again adding a third-party app to your system could always be risky for your anonymity.

Will Kill Switch Guarantee Data Leak Protection?

From one VPN to another, a kill switch’s working could differ in terms of effectiveness. Sometimes a VPN connection goes down and till the time app detects it, data could leak from an encrypted channel to your internet. Also, there are some scenarios in which a VPN’s kill switch works, and sometimes it fails to detect the issue.

VPNs like Nord and Express are trustworthy and reputable in terms of maintaining user security and providing the best working features.
