How does Network Lock work?
When you are not connected to the VPN, your internet traffic may be vulnerable to third-party tampering. To keep your data safe and secure, in case your VPN unexpectedly disconnects, Network Lock is activated and blocks all internet traffic until your VPN connection is restored. Learn more about Network Lock.

When is Network Lock active?
Network Lock is enabled by default. When enabled, Network Lock is active as soon as you are connected to the VPN and when the app is in other connection states. If you disconnect from the VPN manually, Network Lock will not be active although it is enabled in the app settings.
The following table summarizes when Network Lock is active (or inactive) in different VPN connection states.
Note: When the VPN is connecting, it may take a few seconds for Network Lock to become active.
If your VPN unexpectedly disconnects, Network Lock is activated and blocks any internet traffic entering or leaving your device until the connection is restored.
