SSL certificate status explained

We summarise each certificate as Valid (healthy and trusted), Expiring soon (within two weeks of expiry), Expired (past its valid-to date), or Untrusted (self-signed or an incomplete chain). The status reflects a live check against the server right now.

Keep your certificate status healthy

Statuses change as expiry approaches or after a deployment. Checking once is useful; continuous monitoring is better. With a free account, SSLRadar watches your domains and warns you the moment a status turns risky.

Frequently asked questions

What does "expiring soon" mean?

Yes. A free account lets you monitor up to 100 domains from a single dashboard.
