Free SSL Checker

Verify any website's SSL certificate: issuer, validity, expiry date, the hostnames it covers and the TLS version. Paste a URL to run a full check.

Why SSL matters

SSL encrypts the connection between a visitor and a website. Without it, browsers show a 'Not secure' warning, Google ranks the site lower, and any form data is sent in the clear. An expiring or untrusted certificate causes the same problems.

A business site with SSL issues is both a trust and an SEO problem, and a clear reason to pitch an upgrade. LeadWebia checks SSL on every lead it finds.

Why does SSL matter?expand_more

Without a valid certificate, browsers warn visitors the site is "Not secure", Google ranks it lower, and data is sent unencrypted. An expiring or untrusted certificate causes the same problems.

What if it says the certificate is not trusted?expand_more

It usually means the chain is incomplete (a missing intermediate certificate) or the certificate is self-signed or expired. The report will tell you which.

Is it free?expand_more
