QUIC is now a standard, according to IETF.

Well, IETF has done it and has adopted QUIC as a standard that is supposedly set to replace TCP.

https://www.rfc-editor.org/rfc/rfc9000.html

Can someone from Check Point share the plans for QUIC, QUIC-TLS and HTTP/3 treatment?

I have previously inquired about QUIC in 2018, but there is still precious little information on it the KB.

I assume now that it's a standard and we'll start seeing traffic using it, we'll have to support it.
Just a matter of when.
Probably won't be with R81.10 since the content for that release was finalized a while ago.

According to stats from Cloudflare, QUIC traffic is about 15% currently and rising slowly

Hi Dameon,

Do you by chance have an update on this matter? I haven't seen anything in the R81.20 presentations. Anything planned in supporting QUIC?

Thanks,

I believe it's in the longer term roadmap.

in the meantime, i'd suggest blocking the QUIC protocol outbound, so that the browser continues to use TCP and inspection will function as expected
