HSTS Adoption Among Swedish Websites

This page tracks HSTS adoption across Swedish websites. The security header prevents browsers from connecting over insecure HTTP, protecting users from eavesdropping and tampering.

The Strict-Transport-Security HTTP response header instructs browsers to only use HTTPS for subsequent connections. Stronger configurations include max-age (how long to remember), includeSubDomains (apply to all subdomains), and optional preload (add to browser's hardcoded list). Learn more: hstspreload.org.

Adoption: hsts is present on most of these sites, but missing from 11 of 80 sites.
