VPN Kill Switch:
Never Leak Your Real IP

Q: Does kill switch affect speed?

No. VPNWG kill switch operates at the firewall level and has zero impact on connection speed. It only activates when the VPN tunnel drops, blocking traffic until the connection is re-established. During normal operation, it adds no latency or overhead.

Q: Is kill switch always on?

By default, VPNWG kill switch is enabled automatically when you connect. You can configure it in the app settings. We recommend keeping it enabled at all times, especially on untrusted networks like public Wi-Fi.

A VPN is only as secure as its weakest moment. VPNWG's kill switch instantly blocks all internet traffic if your VPN connection drops, ensuring your real IP address is never exposed — not even for a millisecond.

How the Kill Switch Works

VPNWG's kill switch operates at the operating system level, using firewall rules to guarantee zero traffic leakage.

Step 1: Continuous Monitoring

The kill switch constantly monitors your VPN tunnel status. It checks the WireGuard handshake health, packet flow, and connection state multiple times per second to detect any disruption instantly.

Step 2: Instant Block

The moment a VPN drop is detected, all outgoing traffic is blocked at the firewall level. No packets leave your device outside the VPN tunnel. Your real IP never touches the internet — the block happens in under 1 millisecond.

Step 3: Auto-Reconnect

While traffic is blocked, VPNWG automatically attempts to re-establish the VPN tunnel. Once the connection is restored and verified, normal traffic resumes through the encrypted tunnel. The entire process is seamless.

Why You Need a Kill Switch

VPN connections can drop unexpectedly for many reasons. Without a kill switch, every drop is a potential privacy disaster.

Wi-Fi Network Switch

Moving between Wi-Fi networks (home to coffee shop, or between access points) causes your VPN tunnel to drop. Without a kill switch, your device sends traffic unprotected during the transition, exposing your real IP to every site you are connected to.

VPN Server Maintenance

VPN servers occasionally need maintenance or may experience brief outages. If the server goes down, your connection drops silently. A kill switch ensures you stay protected even when the server is temporarily unavailable.

App Crash or System Sleep

If the VPN client crashes or your device goes to sleep and wakes up, the VPN tunnel may not reconnect immediately. During this window, all your traffic flows unencrypted through your ISP, revealing your activity and real IP address.

Unstable Connection

Mobile networks and weak Wi-Fi signals cause frequent micro-disconnections. Each one is an opportunity for your real IP to leak. A kill switch blocks all traffic during these brief interruptions, keeping you protected.

App-Level vs System-Level Kill Switch

Not all kill switches are created equal. VPNWG offers both types for maximum flexibility and security.

apps

App-Level Kill Switch

Blocks internet access only for selected applications when the VPN drops. Other apps continue to work normally. Ideal for users who want to protect specific apps (browser, torrent client) while keeping other connections active.

System-Level Kill Switch Recommended

Blocks all internet traffic at the OS firewall level when the VPN drops. No application, service, or background process can send data outside the tunnel. This is the most secure option and is enabled by default in VPNWG.

Frequently Asked Questions

What happens when VPN drops without kill switch? expand_more

Without a kill switch, your device instantly reverts to your regular internet connection when the VPN drops. This means your real IP address, location, and browsing activity are exposed to your ISP, websites, and anyone monitoring the network. The exposure can last from seconds to minutes before you notice. All active connections (browser tabs, messaging apps, cloud syncs) immediately leak your real IP.

Does kill switch affect speed? expand_more

No. VPNWG's kill switch operates at the firewall level and has zero impact on connection speed during normal operation. It simply sets firewall rules that only allow traffic through the VPN tunnel. These rules are checked by your operating system's network stack with negligible overhead — measured in microseconds, not milliseconds. You will not notice any difference in speed, latency, or throughput.

Is kill switch always on? expand_more

By default, VPNWG's system-level kill switch is enabled automatically when you connect to the VPN. You can toggle it in the app settings if needed. We strongly recommend keeping it enabled at all times, especially on untrusted networks like public Wi-Fi, airports, and hotels. When disabled, your traffic will flow unprotected during any VPN disconnection.

Never Expose Your Real IP Again

VPNWG's kill switch ensures your privacy is protected 24/7 — even when your connection is unstable. Combined with WireGuard speed and Amnezia obfuscation, it's the most secure VPN experience available.
