Consider it a boon to VPN technology; a VPN Kill switch helps cut the connection between the Internet and the VPN connection, whenever anything goes wrong. So, as soon as the network connection drops, VPN Kill Switch comes in the picture as a precautionary measure to break the connection between the web and the VPN server.

There are several reasons for what might lead to network disconnections. A few common ones are listed below.

Presence of Firewall or Antivirus Software

If your device is installed with any antivirus or Firewall, it may result in adequate connection drops. To get past this, users often disable the Firewall to avoid network disconnections while using a VPN. Another workaround to fix this is to set up an exception for your VPN so that your network can bypass it without causing any disruptions.

Network Traffic

Another common reason for what may lead to VPN connection failures is network congestion. If you’re trying to connect to a VPN network at a public location like a cafe, subway, Airport, or anywhere busy, you may have to experience frequent connection drops due to heavy network traffic.

Low WiFi Signal Strength

Most users find this a misconception, but low WiFi signal strength also affects your VPN connection. If the VPN connection is not getting adequate WiFi strength, the connection can be interrupted, leading to data loss.

To fight against all these above-mentioned network disconnection conditions, Kill Switch acts as a savior as it instantly cuts the connection between the web and the server to protect your online privacy.

VPN Kill Switch is broadly categorized into two categories based on how they work. One is an Active Kill Switch that protects your device from connecting to unsafe networks. Another is the Passive Kill Switch that tends to be more secure in comparison. It automatically stops the signal from sending further when it is unable to detect or receive any information from the VPN server.

Hence, in terms of user protection and to keep your online anonymity intact while using a VPN, it becomes utterly crucial to look for a VPN service that comes embedded with a Kill Switch feature.
