port 443
Port 443 is the standard for HTTPS and shows up constantly in certificates, reverse proxies and firewall rules.
Typical reverse proxy use.
Evaluate UDP/443 if using HTTP/3.
Deliberate decision: unauthorized port scanning is an abuse vector and has legal implications in several countries. We prefer a clear, safe reference.
The port indicates expected TLS usage, but real security depends on certificates, TLS settings and the application.
Cleartext HTTP uses 80; HTTPS uses 443.
Encrypted web (TLS 1.2/1.3). Also used by HTTP/3 over QUIC (UDP 443).
