VPN Kill Switch: What It Is and How It Works

A VPN Kill Switch is an advanced feature of a VPN app. Its primary purpose is to protect your data when the VPN connection suddenly drops.

This extra feature will protect users from unwanted IP address leaks and other personal data. When the VPN is unstable, the kill switch will block the internet to avoid the risky connection. 

There are more reasons why a VPN drops the connection, and here are some of them: 

Poor Internet Strength 

A weak Wi-Fi signal is one of the most common reasons VPN connections drop; a VPN disconnects when the internet is slow.

Router Settings

If the VPN keeps dropping connections, it might be due to the firewall settings. Experts say it is best always to enable your firewall to avoid data leakage. 

Network Congestion

Your VPN connection may need to be fixed if there is a lot of Internet traffic. Your device will also be more vulnerable due to frequently occurring network timeouts.

Device Sleep Mode Settings 

Gadgets often put apps into sleep mode to extend battery life, which tends to turn off all idle apps, including your VPN.  

A VPN Kill Switch ensures your device is safe by preventing it from connecting to the Internet. Visibility won't occur, not even in an unexpected connection loss.

VPN Kill Switch: Understanding How it Works

Users may reduce the risk of their private data being leaked by activating the Kill Switch feature, which adds additional levels of protection while using a VPN server. 

The VPN Kill Switch prevents your IP address, location, and digital data from being exposed. Until the restoration of your VPN connection, this feature ensures your privacy.  

Here's how the VPN Kill Switch works:

1. Monitors the VPN Server

A VPN server scans every movement of the server’s connection, while the VPN Kill Switch monitors the server's connections by checking the VPN status for changes. 

2. Detects Any Changes in the VPN Provider

Kill Switch notifies the user after detecting any changes that can result in a connection loss.  

3. Blocks the Internet

Kill Switch protects your online information by disconnecting the device from the Internet whenever it notices a connection drop. This would stop hackers from accessing your information.

4. Restores the Internet Connection

VPN Kill Switch will reconnect to your device's connection as soon as the VPN connection is established again. It also decreases the time it takes for your device to load.  

Types of VPN Kill Switches

Knowing what type of VPN Kill Switches will help users find the most effective VPN subscriptions. 

Here are the two protocols of Kill Switch: 

1. Active Kill Switch Protocols

This protocol only activates after an interrupted connection. When there are connection issues, these Kill Switches investigate the connection drop. 

2. Passive Kill Switch Protocols

This protocol takes effect as soon as your VPN connection is disconnected.  This kill switch will reduce the risk to your data privacy.

These are the two types of passive Kill Switch protocols:

• System Level: This level disables Internet connection for your entire device until the Kill Switch is finished.
• Application Level: The selected apps are only disconnected from the Internet if the VPN connection fails.

These two protocols are safe; however, the passive Kill Switch is more effective and secure. Passive Kill Switch protocols are present in the majority of VPN applications.
