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.
What security headers should my site have?▾
Beyond HSTS, important headers include Content-Security-Policy (CSP), X-Content-Type-Options, X-Frame-Options, and Referrer-Policy. These protect against XSS, clickjacking, and data leaks.
Can I check internal or private domains?▾
No. The tool can only check publicly accessible domains. Internal, localhost, or private network domains cannot be reached by our servers.
How often should I check my SSL configuration?▾
Check at least quarterly or whenever you update your server configuration. SSL certificates typically expire every 90 days (Let's Encrypt) or annually, so regular monitoring is important.
