If you use a VPN, the Kill Switch feature helps protect your data. It blocks the connection as soon as the internet connection is lost. Learn how it works.
How does a kill switch work in a VPN?
Nowadays, people have become increasingly concerned about privacy and security on the internet. This is why the use of VPNs, or Virtual Private Networks, has increased rapidly. VPNs help keep your online activities more secure by encrypting your internet traffic. But what if the VPN connection suddenly breaks? In such a situation, your device can reconnect to a normal internet connection, revealing your real IP address or online activity. This is where a VPN Kill Switch comes in handy. Let's learn how this kill switch works.
What is VPN Kill Switch?
A VPN kill switch is a security feature that temporarily blocks your internet connection if the VPN connection is suddenly disconnected. Its purpose is to ensure that your data doesn't escape directly to the normal internet after the VPN is turned off.
You can think of it as a kind of security lock. As long as the VPN maintains a secure connection, the internet continues to function. A kill switch blocks internet traffic as soon as the VPN connection experiences a problem.
What happens if the VPN disconnects?
When a normal VPN is active, your internet traffic passes through a VPN server. This allows your internet connection to benefit from the VPN's security and encryption. However, a VPN connection can drop due to various reasons, such as Wi-Fi network instability, mobile network changes, problems with the VPN server, or technical glitches in the app.
If the kill switch is off, your device may revert to a normal internet connection. When the kill switch is on, the VPN app recognizes this change and blocks internet traffic. Internet access may resume once the VPN reconnects.
How does it work?
The VPN Kill Switch continuously monitors the status of the VPN connection. As soon as it detects that the VPN tunnel is unavailable, it blocks the device's internet traffic. During this time, websites or apps cannot connect to the internet.
The Kill Switch can re-allow internet access once the VPN connection is restored. However, its functionality and settings may vary between different VPN services.
For whom is it more important?
This feature can be especially beneficial for those who use VPNs on public Wi-Fi networks or are simply more cautious about their online privacy. If your work involves sensitive online activity, the Kill Switch provides an extra layer of security to prevent data leaks when the VPN connection drops.
