VPNs are becoming popular nowadays.

People want to keep their data, messaging, and web history private so that no third party can get access to it.

What is a VPN Kill Switch and Why You Need One

Virtual Private Networks – The What, Why, and How

A Virtual Private Network is an internet tool that creates a more secure and private connection for your web surfing over the internet. It hides your current location and provides you a virtual location from the VPN servers in various parts of the world.

Once you connect, and you have selected your virtual location, your internet identity .i.e., I.P address, will be changed. You’ll take on an IP address based on where the selected server is located. That way, you’ll appear to be browsing the web from that region instead of your physical one.

Why and How?

You can use VPNs for several tasks. Most people use VPNs to protect their privacy by hiding their real identity. However, others use them for various purposes, such as accessing geographically blocked websites or bypassing internet censorship.

The VPN follows the client-server architecture. The data is first transferred to a point in the VPN network, then the VPN client performs the encryption of your data, and it is forwarded through the Internet to the VPN server, which decrypts your data and then it is sent to your target website or IP address.

There are various methods that a VPN uses to encrypt your data. Data travels through a secure tunnel, which assures you the protection of your data, and no one can interrupt your data in between.

The VPN servers are hosted in different countries with various locations by their VPN providers, which the user can choose to connect with the location of his/her choice.

Advantages of Using a VPN:

A VPN offers several advantages to its users. Some of the benefits are listed below.

  • Secure connection
  • Extra privacy

  • No restrictions

  • VPN protocol: Some VPNs perform better when they run on the TCP protocol. There is a higher chance of the VPN connection dropping when this protocol is in use. 
  • Your signal strength: As you are connected to a VPN server through your internet connection. If the signals get weaker “Metro line, elevator” it will directly affect your VPN connectivity resulting in a poor connection, or in some cases, you even lose your connection.

Types of Kill Switch

There are two types for kill switches for a VPN user:

  • System Kill Switch: It completely cuts off the connection from the internet until the problem with your VPN or internet connectivity is resolved. You can turn it on or off easily. You can navigate to your VPN settings where you can enable or disable it.
  • Application Kill Switch: You can select different applications that you want to prevent from using your internet if the Internet drops “torrent apps, messaging apps.” This switch is also referred to as App Killers

Should You Enable It Manually?

In most VPN applications, the kill switch is enabled by default. However, I highly recommend you check it manually by going to the app settings. If it is not enabled there, then you can activate it according to your usage.

Some VPN applications provide the user with the dialogue box to choose in what condition the kill switch should work? As it offers two types of kill switches, system-level kill switch and application-level kill switch as described above.
