HSTS Website Examples
HTTP Strict Transport Security (HSTS) is a security header standard that instructs browsers to only ever connect to a site over HTTPS, protecting against protocol-downgrade and cookie-hijacking attacks on the first request. Our engine detects it through 1 HTTP header check for the `Strict-Transport-Security` response header. Like CSP, this is a security-configuration signal we surface alongside builder/technology detection, not a vendor or platform identification. Reference: MDN's HSTS documentation.
