    Hey all

    Is there a setting somewhere in the OS or some way to make sure that all network activity is disabled if the VPN connection goes down? Sort of like a "kill switch" in case the VPN connection is lost without your knowledge.

    Either way it would be a great feature to have for a device that's supposed to be all about security.

    When you set-up any Wi-Fi connection you can add a VPN in the profile.

    It's not a kill switch, but it makes sure that whenever your connect to this Wi-Fi, your VPN boots automatically and it would reboot in case the VPN connection is lost.

    With 10.3.1, there's a new option that lets you automatically connect the VPN to Wi-Fi and/or Mobile. But anyways, I went ahead and added them to the Wi-Fi profiles like you suggested. So if the VPN connection is lost, will it kill the Wi-Fi connection too? That's basically what I was hoping to achieve. Of course, if the Wi-Fi connection is lost, it reverts to Mobile, which will leak your data during the time that the VPN is down.

    Same goes for Mobile. But there's no option that I can find that will enforce this for the Mobile data.

    It is not a classical kill switch as I understand it, but your question is interesting.
    I speculate that there is no data leakage while the VPN connection is (re-) established, otherwise this feature would have been very badly implemented by BlackBerry.

    However, I didn't know this very useful feature you've described.
    Thanks for that.

    Ya, it's fun finding those nice little features that BB sneaks into their releases without telling you about

    Anyway, consider this simple scenario:

    You're connected to Mobile (or Wi-Fi), through your VPN.
    The VPN loses connection. It disconnects, for whatever reason. Maybe you went out of Wi-Fi range, in which case your device reverts to Mobile data, thus leaking information.
    While the VPN is attempting to reconnect, which could take several attempts, your Mobile or Wi-Fi connection continues to function, transmitting data (maybe you were in the middle of a download or email sync).
    Your data is leaked, even if temporarily.

    Some VPN service providers offer a "kill switch" in their software. There are also more manual ways of doing this by editing routing tables in Windows and enforcing network traffic in a certain direction, for example. But on a BB??

    Currently, you'd have to notice by the vpn icon in top right corner and take action. Coincidentally, I just heard of that feature yesterday on android or windows OS.
