Hello Sudarsan,

You can use the Application Control module to block Yahoo and allow the rest. Set all the Yahoo signatures to Block. Additionally, please enable "certificate-inspection".

Hi Hmtay,

I used to block application control  for yahoo signatures . I  used ssl inspection . 

If i used certificate inspection   facebook ,youtube will allow?

I already blocked through ssl inspection .

Hi

I am using fortigate 240D firewall. In that I was created the policy for blocking google drives except gmail.

So I add the filter in the application control then block the google drive. 

Once I opened the drive it was not opened. But after opening the gmail, the drive immediately open. How to restrict that ?

thanks

May be QUIC need to block.

Hello,

If what you refer to as "ssl inspection" is deep-inspection, e.g. doing a Man in the Middle, that will work too.

QUIC has to be blocked if you are trying to access Google services on Chrome.
