Performs a fundamental check to determine if a URL is served over HTTPS (HyperText Transfer Protocol Secure). It verifies if the URL starts with "https://" and attempts a basic connection to see if it's accessible. Use cases: quickly verifying if a site is using HTTPS with our SSL certificate test, initial check before deeper SSL certificate analysis. Benefits: HTTPS is crucial for user trust, data security, and is a minor Google ranking signal. This HTTPS checker helps confirm its basic presence. Note: This tool does not validate the SSL certificate details (issuer, expiry date, chain of trust).
