Hi all,

How can i block ultrasurf extension installed on chrome? (ultrasurf, other proxy..)

I have just started using this product. I tried a few ways i saw on this site. Unfortunately it does not work. And i am really tired.

Hello,

We performed some tests on our XGs, and found that XG is not able to block extensions installed in browsers. If you block the Ultrasurf's categories in AppControl and Web, it will take a while to start, but traffic will be redirected to another Ultrasurf server and the XG will not block this traffic.

We do not try with the decrypt and scan option enabled, it might work.

Kindly regards.

Hi folks,

have you tried the XG block filter avoidance application filter as well as your additional settings?

You will need to fine tune it using the logs and user complaints as to sites they can't reach and would normally be able to.

Hello guys,

It's completely impracticable try to block using this thread. Is going to always be another server or another hop. The analyst will work 24h a day just mapping and blocking.

Kindly regards
