QUIC inspection and how it works

QUIC is an UDP based transport protocol. Compared to TCP / TLS, it gives faster connection setup and eliminates the head-of-line blocking that is present in TCP. The reason behind faster connection setup is the reduced number of handshake messages. QUIC uses TLS 1.3 for the handshake and generation of encryption keys. It takes only one round trip to establish a path for communication.

QUIC is an integral part of HTTP/3 protocol which is widely used by web applications.
