UDP Traffic on 443, application generating it

Hi Dwijadas Senapati,

Thank you for reaching out to the Community! 

Google's QUIC protocol uses UDP 443, you can block it on the firewall. 

Check out the following document for more info: Advisory: Google's QUIC protocol bypasses scanning on Sophos XG Firewall.

Thanks,

Thanks for your reply.

Thats seems to be a lot of traffic or its a false indication by the firewall ? Upon blocking any issue within the network ?
