Security tool

SSL & Domain Health Checker

Run a TLS handshake reachability check against any domain.

What this checks (and what it can't): this runs entirely in your browser and only tests whether the host answers a request over HTTPS. Because the browser hides cross-origin responses, it cannot read the certificate (expiry, issuer, chain), confirm the cipher, or tell a real TLS failure apart from a CORS block. Sites with strict CORS or bot protection may show as "could not verify" even when perfectly healthy. This is reachability, not a certificate audit. For a real audit use SSL Labs or your browser's padlock → Certificate viewer.

Frequently asked questions

What does this tool actually test?

This tool performs a browser-side TLS handshake reachability probe — it confirms whether your browser can establish an encrypted connection to the domain. It does not read certificate details such as expiry date, issuer, SANs, or cipher suite, because browsers do not expose certificate data to JavaScript on cross-origin requests. For full certificate inspection, use SSL Labs or your browser's built-in certificate viewer.

My site passed — does that mean my SSL certificate is healthy?

A passing reachability probe means the TLS handshake succeeded at the moment of the test. It does not confirm the certificate's expiry date, whether it covers all required subdomains, or whether weak cipher suites are in use. Elevate recommends monitoring certificate expiry proactively — an expired certificate causes browser warnings that immediately erode client trust.
