About
The HTTP Strict Transport Security (HSTS) standard is a web security mechanism that ensures a user's browser always connects to a website using HTTPS, preventing insecure HTTP access.
It is enforced through the Strict-Transport-Security response header, which defines a policy duration, can apply to all subdomains, automatically upgrades HTTP requests to HTTPS, and protects against protocol downgrade attacks and cookie hijacking.
QUIC is a transport layer network protocol built on UDP that provides encrypted, low-latency data transfer, underpins 
HTTP/3, and was originally developed by Google.
It combines transport and security in a single protocol, establishes connections in as little as one round trip, supports multiple independent streams within a single connection to avoid blocking, and preserves sessions when a device changes IP address or network.
