Check SSL Certificate Status Online
Check whether a domain's SSL certificate is valid, expiring soon, or already expired — instantly, online.
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.
