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 (Secure Sockets Layer) certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection between a web server and a browser. When you see HTTPS and a padlock icon in your browser's address bar, the site has a valid SSL certificate. Modern implementations actually use TLS (Transport Layer Security), the successor to SSL.
SSL certificates protect sensitive data transmitted between users and websites by encrypting the connection. Google uses HTTPS as a ranking signal, so SSL directly impacts SEO. Browsers now mark HTTP sites as "Not Secure," which can damage user trust and increase bounce rates. SSL certificates also prevent man-in-the-middle attacks where attackers intercept data in transit.
Domain Validated (DV) certificates verify domain ownership and are the simplest to obtain, often available free from Let's Encrypt. Organization Validated (OV) certificates verify the organization behind the domain. Extended Validation (EV) certificates require thorough verification of the business entity. All types provide the same level of encryption; the difference is the level of identity verification.
