SSL certificate checks
How certificate expiry monitoring works and when it should warn you.
An SSL certificate check reads the certificate served by your site and tracks how long it stays valid.
What it reads
The check inspects the certificate's expiry date on each run and counts down the days remaining.
When to be warned
A warning is useful while there is still time to act. Alerting around two weeks before expiry gives most teams enough runway to renew.
