I have a TZ400 and I am trying to block Google search. I used the instructions below and was able to block YouTube. However, the same instructions don't block Google Search.
I see the log message, but nothing is blocked.

Are you using DPI-SSL? If not you're missing 80% or more of your traffic...
I think I enabled it correctly. The category shows up in the log, it just isn't blocked.
Hi @TomJones, as @TKWITS correctly mentioned you need DPI-SSL, but you also need to ensure that you create a firewall rule (usually from LAN-WAN but depends on your Source Zone) outbound to deny UDP 443 (Google Quic Protocol) otherwise DPI-SSL will not work with any Google sites
