Want full protection from possible leaks? Turn on our Firewall feature so that if the VPN connection fails for whatever reason, no data will leave your device, keeping you protected.
A firewall blocks ALL connectivity outside of the VPN tunnel to ensure zero leaks of any kind if the VPN disconnects, while a Killswitch allows still allows packets to leave your device between the time your VPN disconnects and the program(s) you have in use realize the VPN is disconnected.
A firewall is a proactive solution, whilst a killswitch is a reactive measure. If the VPN connection drops, there is nothing that needs to be done, and not a single packet can leave the machine, since the firewall will not allow it. In geek terms it fails closed.
Our firewall blocks all types of leaks, including (but not limited to): traffic leaks, DNS leaks, IPv6 leaks, and maybe even tears.
The Firewall setting is available on our Windows, Mac and Linux apps. On Android and iOS, you can use “Always On VPN”, which has the same effect and is built directly into the OS. Both features are located under “Connection” preferences.
This will enable the firewall when you connect to a Windscribe location and disables it when you disconnect. It also keeps your connection secure by disabling your internet if the application crashes unexpectedly or the connection to the VPN server is interrupted.
This gives you full control of when you want to have the firewall on and off. Keep in mind that if you turn it on yourself, you only get internet when connected to the VPN or until you turn the firewall off. Closing the application will turn the firewall OFF but only if you close it yourself, not if it crashes.
This will restrict your internet entirely to using the VPN. Your internet connection will be disabled until you connect to a location or disable Always-on mode. Even if the application crashes, you exit it entirely or your computer restarts, you won't have internet until you reconnect to a Windscribe server. This is the most secure mode for our firewall.
