How CertRadar checks this

We perform a live TLS handshake to zoom.us:443 from our servers, read the certificate the server presents, and report the expiry date, issuer, and health signals. No login, no spoofed data, no third-party cert logs — this is what your browser sees right now.

The same check runs daily on every domain you add to your CertRadar watchlist. You get emails, webhooks, or Slack messages 30, 14, 7, 3, and 1 days before anything expires — including the cases auto-renewal quietly fails to handle (cert renewed but not deployed, subdomain not covered, weak signature).
