I've seen first hand how the QUIC protocol has made things more difficult for Network Admins. A wireless vendor who shall remain nameless (Not Cisco) was (and as far as I know is still) having trouble with QUIC to the point where they suggested to their client to turn off the protocol on all of their chromebooks (over 600 at the time). It's refreshing to see that we (Cisco) are taking the challenge head on in regards to how to see within those QUIC streams and posture security.
