QUIC is a protocol developed by Google that uses UDP for its transportation and supports multiplexed connections between two endpoints. This provides a security equivalent TLS/SSL and reduces connection and transport latency.
When using Chrome, many Google services like Gmail and YouTube will prefer QUIC over TCP TLS
In Chrome version 70, Google is updating its QUIC protocol to version 44, Application and Threat Content Update version 8080 updates our existing "quic" App-ID to remain compliant with QUIC version 44.
To prevent running into issues when Google releases their update on October 16th, it is recommended to update the content packages on your firewalls to version 8080 or above at your earliest convenience.
