How Does a Kill Switch Work for Your VPN Connection?

VPN Kill Switch, as already mentioned, is a powerful feature to own. The job of this feature is to ensure that there is no data leak if the VPN connection drops for any reason. It becomes active as soon as a VPN connection trips and prevents IP address (mask your IP), geolocation, online activities, and other sensitive information from getting leaked in extremely dangerous cyberspace.

Now, you must be curious to know how it accomplishes such a critical and complex-looking job. Well, it makes it happen by monitoring the VPN connection around the clock. The VPN kill switch will have Hawk’s eyes on the VPN connection so that any minor or significant problem/glitch is spotted instantly. But it’s more than this.

Here are the four stages of a VPN’s kill switch operation:

  • Constant monitoring: As mentioned above, monitoring is the first stage of the VPN kill switch’s function. The IP address status and activeness of VPN connections are monitored constantly.
  • Issue detection: While monitoring, the VPN kill switch looks for any abnormalities in the VPN’s functions.
  • Issue blockage: Once any errors or issues are spotted, a VPN kill switch instantly blocks the connected apps or devices from connecting to the internet. This blocking continues as long as the issue persists.
  • Connection restoring: Once the trouble is fully resolved, a kill switch restores VPN connections automatically.

All this happens so quickly and seamlessly that VPN users won’t be able to find out any of this. But not all kill switches provide such quality protection. Some even don’t become active when the internet connection drops. Hence, you must pick the ideal and best VPN kill switch.

What Can Cause the Internet Connection to Drop?

We know that a VPN kill switch is a savior when a VPN connection fails or drops in between. But why it happens? Why did the internet connection break in the first place? There are three major events causing this issue.

The first and most prominent one is poor firewall or router settings. Even though VPN comes as a pre-built tool, certain setting changes are required to function properly. If these settings are not proper, VPN connections will drop abruptly.

To ensure this isn’t causing a connection drop, you need to optimize these settings and relaunch the VPN connection.

The other 2 are:

VPN protocol picked: The kind of VPN protocol you pick decides the VPN connectivity. Specific protocols like TCP make the connection stable. Default UDP is generally not very much functional. So, you must check if you’re using the right internet protocol.

Improper signal strength or network congestion: VPN services allow end-users to connect with distant servers. But this doesn’t mean that local WiFi connections are not adequate. Connecting with distant servers often has connectivity issues unless you use a powerful VPN.

Also, if you’re connected to WiFi shared by multiple people at a time, the VPN connections will surely drop.

Types of VPN Kill Switches

A VPN kill switch is a highly pivotal technology offered in two varieties to meet all sorts of requirements. Here are those two types.

  • System-level Kill Switches

An elementary variety, a system-level kill switch for VPN tracks the activeness of VPN service providers. It ensures that internet connectivity is not via mobile data or WiFi.

It completely disconnects the internet connectivity to the concerned devices unless the VPN connection is restored completely. Hence, connectivity is not restored even with weak VPN connectivity, and the possibility of an IP leak is nearly negligible. Its setup is seamless and hardly requires any setup and installation.

  • Application-level Kill Switches

Even though it’s not as safe as a system-level kill switch, this variety is often preferred when only two applications are concerned. It lets you decide which app needs kill switch VPN’s protection and prevent it from connecting with the internet with poor or no VPN protection.

It works great when you don’t want VPN security for every application but want to protect IP leaks from specific apps. It’s mainly used for solutions like browsers, video calling apps, email apps, and torrent clients.

Who Must Use a Kill Switch Feature?

While hiding real IP addresses is recommended for everyone willing to access safely and keep cyber threats at bay, certain people must not have an internet connection without the aid of a VPN kill switch. What we mean is:

  • Activists, whistleblowers, and journalists must use a VPN kill switch to hide their online identities.
  • Those using P2P tools must use this technology to ensure their P2P activities are not exposed, as it’s not allowed in many countries.
  • Anyone sharing confidential documents and data online should use an advanced VPN kill switch to ensure sensitive information is not leaked when the connection drops suddenly.

VPN Kill Switch – Why to Use It at First Place

We have greatly praised the utility of the VPN kill switch, but why should one be bothered about using it? Is IP address leak prevention the only reason?

There are many reasons behind adopting this technology – other than protecting against IP address leaks.

Whether you’re in a heavily censored country like Russia (VPN for Russia), Turkey, or North Korea, your location can still restrict your internet freedom and monitor your online activities. The VPN kill switch technology ensures that your IP address remains protected from the sudden non-functionality of VPN connections, no matter where you are.

It will keep your data and secrets covered no matter what, which is very important these days. Every Redditor has the same opinion as us:
