A VPN kill switch feature has become a need of the hour since we live in a dangerous online world. Cybercriminals like hackers, scammers, and others always keep an eye on our web surfing activities. Additionally, they make full use of the situation as soon as they realize our original identity is exposed online.

In this situation, you should use a VPN service that provides a kill switch feature. This is one of the most effective ways to secure your privacy from the prying eyes of hackers and other cyber goons.

Continue reading this guide to know what is a kill switch and why do you need it to enhance your online privacy all the time.

What is a VPN Kill Switch?

A VPN kill switch helps you protect your digital footprints when your VPN connection does not work properly. It disconnects your device, be it Windows, Mac, Android, or iOS, from the internet as long as your VPN connection stops working.

Thus, your original IP address will not fall into the wrong hands of cybercriminals. Furthermore, you can protect your internet connections against prying actors to a certain degree.

Why should I use a Kill switch feature?

There can be many reasons that compel us to enable a kill switch feature on our preferred devices. In short, you need it the most when you do not want to find yourself in hot waters because of hacking, privacy invasion, phishing attacks, malware, and other cyber threats.

To understand the importance of the internet kill switch, let us discuss this example. When a kill switch feature is enabled on your device, you cannot browse the internet as soon as the VPN connection is disconnected.

In case you turn off the kill switch feature, you can surf the web normally from anywhere. However, your actual whereabouts can be exposed online if a VPN service stops working unexpectedly.

Types of VPN Kill Switch

There are two major VPN kill switch types, these are active kill switch and passive kill switch. An active kill switch plays its role when your VPN connection is interrupted. In reality, it does not allow you to connect to an insecure network.

In simple words, it completely blocks your internet connection to your devices immediately if a VPN connection stops working. As a result, you can secure yourself from different security risks like IP leaks, DNS leaks, and WebRTC leaks too.

If we talk about a passive kill switch feature, it is more useful than an active kill switch. When activated, a passive kill switch feature lets you select the specific apps you want to stop from connecting to the internet in case your VPN stops working.

If a VPN app disconnects, your chosen apps like Firefox or Chrome browsers, Skype, WhatsApp, etc., will no longer work. Hence, you can protect your crucial data comprehensively.

Are VPN connections reliable?

In general, VPN connections are reliable as they let you surf the web without compromising your privacy. Apart from this, VPN providers that do not share their server networks with other VPN services and enable you to connect to your desired server locations from anywhere are considered reliable.

On the contrary, if VPN services have a limited server count and do not allow you to connect to your preferred server locations as and when needed, they are not trustworthy, and you should not use them to secure your privacy.

Why do VPNs disconnect (major causes)?

VPNs’ importance has grown to another level since they help you browse the internet from anywhere securely. As the number of VPN users increases worldwide, they also face disconnection issues at times.

There are three primary reasons behind the VPN disconnection hassles, including:

  • Firewall settings
  • Selection of VPN protocol
  • Unreliable internet connections


Different privacy tools like firewalls, antivirus, and anti-spyware software can affect the performance of a VPN connection a great deal. Therefore, you should disable them before activating a VPN service on your devices.  

Selection of VPN protocol

At times, your VPN protocol selection does not allow VPN connections to work appropriately. Hence, you should switch to another tunneling protocol to see if your VPN connection is working smoothly or not. 

For example, you can change your default UDP protocol to TCP if your VPN connection is not stable on the former protocol. By doing so, you can overcome the VPN disconnection problems instantly.  

Unreliable internet connections

When you select a VPN server location, you often forget one crucial thing: your Wi-Fi connection. You have to use a reliable Wi-Fi network when using a VPN service. Otherwise, you will keep facing VPN disconnection issues because low Wi-Fi signals weaken your VPN connections significantly.

What are the impacts of VPN network reliability issues?

The impacts of VPN network reliability issues are dangerous security-wise. If you are a torrent user, you need to have a VPN with a kill switch feature in your armory all the time. Otherwise, your actual IP address can be exposed to different surveillance actors like ISPs, copyright holders, etc.

When you use a VPN to secure your torrents downloading activity, it becomes a lengthy process. Therefore, you should try different workarounds to speed up your torrenting tasks. Here is what you should do:

Perform torrenting via Vuze BitTorrent client

The Vuze BitTorrent client is a lightweight and end-to-end software app that does not hamper your computers’ speed. Moreover, it helps you download torrents quickly on your preferred devices.

Interestingly, it can efficiently work in tandem with a VPN. Vuze will not route data packets through the public IP network if your VPN service becomes unreliable. It will keep trying to route the data network through a VPN.

However, the torrents will not be downloaded successfully. But, it will not reveal your actual IP address online.

Configure firewall settings manually

Luckily, you can secure your torrents downloading activities by configuring the OS firewall settings on your devices manually. Thus, it can quickly block the downloading task as soon as your VPN service stops working or disconnects.

Other ways to secure yourself against VPN disconnections

VPN disconnections are common these days because millions of people are working remotely due to the COVID-19 pandemic. However, you can still use different tools that allow you to protect yourself against VPN disconnections. 

These tools are VPN Watcher and VPNetMon. You may use a VPN Watcher to monitor the performance of your VPN connections. It does not allow control apps to send your data to the network if a VPN connection fails out of the blue.

Like VPN Watcher, you can also opt for VPNetMon that does not entirely shut down the internet connection. It just closes specific apps on your device that can expose your actual IP address on an unprotected network.
