Is your HTTPS certificate healthy?
Enter a domain to see its SSL certificate validity, expiry date, issuer and the domains it covers.
About this tool
An SSL/TLS certificate encrypts your visitors' connection and enables the browser's padlock. An expired or invalid certificate triggers a browser security warning and drives users away. This tool reads the certificate straight from the server and shows validity, expiry, issuer and the covered domains (SAN).
Frequently asked questions
