Verify the SSL/TLS certificate status of any domain. Enter a domain name to check its HTTPS security configuration and get links to detailed analysis.
An SSL certificate authenticates a website's identity and enables encrypted connections. When you see HTTPS and a padlock icon, the site has a valid SSL certificate. Modern implementations use TLS (Transport Layer Security).
SSL protects data in transit, is a Google ranking signal, and prevents browsers from marking your site as Not Secure. It also prevents man-in-the-middle attacks.
Domain Validated (DV) certificates are simplest, often free from Let's Encrypt. Organization Validated (OV) verify the business. Extended Validation (EV) require thorough verification. All provide the same encryption level.
