Unable to block Hoxx VPN

Vineeth Penugonda

Hi guys,

I am unable to block the Hoxx VPN extension on firefox. I followed the Application filter recommended settings for better application detection (https://soph.so/WtpQzU). The application uses port 80/443 for VPN servers. Sophos XGS is unable to block the VPN.

    Restart and again this steps given below

    It is a good idea to disable VPN’s on your browsers if you are concerned about a VPN. You shouldn’t allow your Opera or Firefox browser to be configured to use a VPN.
    The second thing you should do is uninstall applications that have VPN’s installed. Many anti-virus programs have VPN’s embedded.
    3 – Block all VPN traffic from your network.

    This may help you,

    Hi Rachel,

    I don't own the end client devices so I can't allow/disallow VPN apps and extensions they use on their device. I am already blocking all VPN traffic from the network. 

    "Non-SSL/TLS traffic on port 443" and "VPN Over 443" application signatures are broken. Fixing them will fix this issue.
