Frequently Asked Questions
What does this tool check?▾
It checks whether a domain supports HTTPS, inspects security-related response headers (HSTS, CSP, X-Frame-Options), and verifies the connection is working properly.
Why can't I see the full certificate details?▾
Browser-based tools cannot inspect TLS certificate details directly. For full certificate inspection including issuer and expiry dates, use command-line tools like openssl.
What is HSTS?▾
HTTP Strict Transport Security (HSTS) tells browsers to always use HTTPS for a domain. It prevents downgrade attacks and cookie hijacking.
Is this tool free?▾
Yes. The check runs through our server to test the connection, but no data is stored.
