What Is a VPN Kill Switch — And Why You Actually Need One

A VPN protects your privacy by encrypting your internet traffic — but what happens when the connection drops? Your real IP address and activity can slip out in seconds, before you even notice.

That's where a VPN kill switch comes in. The moment your VPN disconnects, a kill switch automatically blocks all internet traffic so nothing travels outside the encrypted tunnel. When the VPN reconnects, everything resumes — no manual action needed.

In this video, you'll learn: ✔ Why VPN connections drop more often than most people realize (weak signal, switching from Wi-Fi to mobile data, busy servers) ✔ How a kill switch works at the system level ✔ The difference between a system-level kill switch and an app-level kill switch ✔ Why public Wi-Fi in cafes and airports is exactly where this matters most ✔ How Avast VPN's built-in kill switch protects you quietly in the background

Privacy that quietly lapses isn't really privacy. Avast VPN has a built-in system-level kill switch that catches those gaps for you — automatically.
