Block VPN Exntesion/Add-on On Chrome, Opera browser

dear all,

I asked this question 9 months ago but unfortunately, still I have no solution for it although I have installed the Security Appliance SSL CA on the end user's machineI've Sophos XG Home that block all Entertainment Web Browser. Problem is users use VPN add-on on Browser such as Hoxx VPN, Touch VPN, Ultrasurf,... so user still can access to Entertaintment site like "".

I add application rule that lock all VPN, Proxy. But still can't lock VPN Add-on.
