Kill Switch: No VPN, No Internet

A VPN connection can drop unexpectedly — switching networks, entering an elevator, or during a server restart. Without a kill switch, your device silently reverts to an unprotected connection, exposing your real IP address and unencrypted traffic. VPN Wave Kill Switch instantly blocks all internet access the moment the VPN tunnel drops, ensuring your data never leaks.

Instant Leak Prevention

The moment your VPN connection drops, all traffic is blocked. Your real IP address is never exposed, not even for a fraction of a second.

Automatic Reconnection

VPN Wave automatically re-establishes the encrypted tunnel after a disruption. Traffic resumes only when the secure connection is confirmed.

DNS Leak Protection

The kill switch prevents DNS queries from leaking to your ISP during connection drops, keeping your browsing activity completely private.

Network Switch Safety

Moving between Wi-Fi and cellular? The kill switch keeps you protected during the transition so no unencrypted packets slip through.

The VPN Wave Kill Switch works at the network level on iOS, using the system VPN configuration to enforce an all-or-nothing policy. When enabled, the operating system itself prevents any traffic from bypassing the encrypted tunnel. If the VPN connection drops for any reason — network change, server restart, signal loss — all outbound traffic is blocked until the secure tunnel is re-established. This happens automatically with no user intervention. The kill switch protects against DNS leaks, IPv6 leaks, and brief connectivity gaps that other VPNs silently ignore.

What is a VPN kill switch?

A kill switch is a security feature that blocks all internet traffic if the VPN connection drops unexpectedly. This prevents your real IP address and unencrypted data from being exposed during brief connectivity gaps.

Does VPN Wave have a kill switch on iPhone?

Yes. VPN Wave includes a system-level kill switch on iOS that blocks all traffic when the VPN tunnel drops. It activates automatically and requires no manual configuration.

Will the kill switch disconnect my apps?

Apps will pause internet access momentarily while the VPN reconnects. Once the secure tunnel is re-established, traffic resumes automatically. Most users do not notice the brief interruption.

Does the kill switch protect against DNS leaks?

Yes. The kill switch prevents all traffic — including DNS queries — from bypassing the VPN tunnel, eliminating DNS leaks during connection drops.

Should I always keep the kill switch enabled?

Yes. There is no downside to keeping it on. The kill switch only activates when the VPN connection drops, ensuring your real IP is never exposed — even for a moment.

Does the kill switch work when switching from Wi-Fi to cellular?

Yes. VPN Wave's kill switch blocks all traffic during network transitions between Wi-Fi and cellular. Once the VPN tunnel is re-established on the new network, traffic resumes automatically.
