What is a VPN kill switch exactly, and how does it work?

What is VPN kill switch? By masking your internet protocol address and encrypting the data you send and receive online, a virtual private network (VPN) can provide you with more online anonymity and privacy. By acting as a safe, encrypted tunnel for your data, a virtual private network (VPN) transforms a public internet connection into a private network. However, what happens if your VPN provider’s connection to you is suddenly cut off?

If you lose access to your VPN for an extended period of time, your IP address and online activities will almost certainly become public. Because cybercriminals may use sensitive data such as your personal information to commit crimes such as identity theft and other types of online fraud, you do not want this to happen to you.

Given that VPNs are supposed to give increased security rather than decreased security, this raises a conundrum. In this case, a VPN feature known as a kill switch, which is provided by some VPN providers, may be useful. When your VPN connection is lost, a kill switch can block your device from connecting to the internet, ensuring your anonymity is maintained while you wait for your VPN connection to be restored. A kill switch prevents the disclosure of your IP address, location, or identity by mistake.

This article will define what is VPN kill switch, explain how it works, discuss the many types of VPN kill switches, discuss the reasons for VPN disconnections, and discuss how a VPN kill switch may help protect you.

How does a VPN kill switch work?

Understanding how virtual private networks (VPNs) work is crucial in order to comprehend how a kill switch works. VPNs construct a data tunnel between your local network and a remote server situated in another place. If your device is connected to a virtual private network (VPN), your web activity will be attributed to the VPN server’s IP address rather than your actual IP address. This creates the illusion that you are in a different location – while concealing your true position.

A VPN conceals not just your IP address and location; it also conceals your browser history and website activity — which may contain sensitive information such as passwords and bank account details. VPNs obscure this information by encrypting the data you send and receive over a Wi-Fi network.

The situation is as follows. If your internet connection — and thus your VPN server — is disrupted or loses access, your laptop, smartphone, or other device is likely to revert to the public IP address provided by your home Internet Service Provider. As a result, your online activity and browsing history, as well as your IP address and geographic location, may become instantly accessible to and trackable by others.

By utilizing a VPN kill switch, you may strengthen your security by preventing this sudden and unexpected visibility. How? This is accomplished by immediately disconnecting you from the internet whenever your IP address changes or your VPN service terminates.

Bear in mind that not all VPN providers offer this option, so keep that in mind while choosing the VPN provider that is best suited to your needs and requirements.

Additionally, keep in mind that while some VPN providers may offer pre-activated kill switches, many kill switches are not. If this is the case, you must manually activate the kill switch in your VPN client by selecting it from the kill switch menu.

VPN kill switches come in a variety of configurations.

VPN kill switches are not available on all VPNs, and they come in a variety of flavors, including system-level kill switches and application-level kill switches.

What constitutes a distinction between the two? At the system level, a kill switch triggers the complete termination of all network activity. On the other hand, a kill switch that acts at the application level is more flexible. It enables you to choose specific applications or online services to terminate before to reconnecting to your VPN connection.

VPN disconnections can be attributed to six distinct causes.

When driving through a tunnel and losing your Wi-Fi signal, connections to virtual private networks (VPNs) are not always lost. Six common reasons for VPN disconnections are detailed below.

Setting up a firewall or router. If you frequently lose connection, an issue with the settings of your firewall, antivirus, or spyware application may be to cause. If this occurs, consider disabling them. If that does not work, you will need to add your VPN to the list of exceptions on the configuration page for your firewall.

VPN protocols are categorized into several categories based on their kind. TCP, which is a VPN protocol, may be more dependable and stable than UDP (UDP). If you’re currently using UDP, you might wish to experiment with switching your network’s protocol.

The Wi-Fi signal is either unavailable or very weak. If your Wi-Fi signal is weak, your connection may be lost. If you lose your internet connection, it is hard to reconnect to your VPN service.

The network is congested. Congestion caused by high internet traffic can result in the loss of your internet connection.

Interference from the Internet Service Provider. Interference with your internet service provider may result in you losing connection to your VPN server.

VPN client and server issues. While VPN providers are frequently quite secure, with multiple servers placed throughout the world, it is conceivable for something to happen to render a server inoperable. If your VPN provider’s servers are down, your connection will be lost.

What does a VPN kill switch mean?

VPN kill switches are critical because they ensure that your privacy is maintained in the event of an unforeseen occurrence, which nearly always occurs at some point.

If you lose your VPN connection, your computer or device will almost certainly revert to the IP address supplied by your Internet service provider. It’s entirely possible that you’re unaware of it. This is something you do not want to happen because it will imply that you will lose the privacy and anonymity that a VPN gives.

Whether you’re responsible for sensitive data from your bank account or your employer, keeping your online privacy is important to your success.

The VPN kill switch ensures your internet connection is immediately cancelled if your VPN connection is lost. Consider the alternative: risking the possibility that your sensitive information will be viewed by others. To help protect your privacy and security, it’s a good idea to set a VPN kill switch on your computer.

5 Reputable VPN Providers that Include a Kill Switch

A VPN service must provide a kill switch as a first line of defense to prevent your IP address and other sensitive data from being accidentally transmitted across an insecure connection.

Consider the following example of how certain VPNs create their kill switches:

ExpressVPN: Most remarkable features is that its kill switch, nicknamed Network Lock, is enabled by default. It is accessible via the desktop programme included with the most recent versions of Windows or Mac, as follows: Mac OS X 10.10 (Yosemite), Mac OS X 10.11 (El Capitan), and macOS 10.12 (Sierra) are all supported, as are Windows 7 SP1, Windows 8, Windows 8.1, and Windows 10. (High Sierra).

NordVPN: Supports both mobile and desktop devices with a kill switch capability. When the VPN connection is broken, the desktop version for Windows and Mac automatically shuts down selected applications, while the mobile version for Android and iOS disables internet access on the entire device.

VyprVPN: Not only does it have a kill switch for Mac and Windows, but it also has detailed settings for two distinct options: the App and System options. The kill switch is engaged only when VyprVPN is running and prevents you from accessing the internet until you connect to a VPN server. The kill switch will remain active at all times, even when the VyprVPN software is not in use or operating.

TorGuard: TorGuard is a supplier of “anonymous VPN” services that was created exclusively for torrent users. It has an IP-bind kill switch, as well as DNS Leak Protection and a no-logs policy.

HideMyAss: Their premium plan contains a kill switch feature called Secure IP-Bind Technology, a subset of IP-binding technology. Despite its on-demand and randomized server switching capabilities, it is not recommended for BitTorrent users.

Are you a VPN subscriber who does not have a kill switch?

If this is not the case, switching service providers may not be required.

Here are five basic methods for “rigging” your connection with free kill switch protection:

1. VPN Watcher is a simple, lightweight application that acts as an automated kill switch, blocking your running applications from connecting to the Internet when your VPN connection fails. 2. It uses less than 2MB of RAM and has no effect on the performance of the CPU.

2. VPN Lifeguard is a portable, free, and open-source tool that prevents you from running programmes or becoming insecure if your VPN connection is lost.
