HSTS Test
Check if HTTP Strict Transport Security is enabled.
About the HSTS Test
Verify HTTP Strict Transport Security (HSTS) is enabled and correctly configured. Check header and preload status. Sign in. To use it, enter a full URL including https:// and run the test. Regular checks catch regressions early — broken tags, slow pages, and security gaps compound silently when nobody looks. Sign in to run checks.
