SSL Checker

Enter a domain name and we will check the SSL certificate installed on it: validity, issuer, covered names and the certificate chain.

Why it matters

What a certificate problem costs you

Visitor trust

Browsers show a “Not secure” warning when a certificate expires or does not match, and visitors leave right away.

Better search ranking

Google uses HTTPS as a ranking signal, so a healthy certificate is part of your SEO.

Data protection

The certificate encrypts traffic between visitors and your site, protecting passwords and payment details.
