Frequently Asked Questions
How does the SSL expiry checker work?
We connect to your domain over TLS and inspect the certificate directly — the same way a web browser does. This gives us the exact expiry date, issuer, and validity status.
What happens when an SSL certificate expires?
Browsers will show a scary "Your connection is not private" warning, which drives away visitors and kills trust. Search engines also penalize sites with expired certificates.
Can I check SSL for subdomains?
Yes! Unlike domain expiry (which only applies to the root domain), SSL certificates can be different per subdomain. Enter any subdomain like app.example.com or mail.example.com.
How often are expiry notifications sent?
We send the first notification 7 days before expiry, then daily reminders. We also detect certificate renewals automatically and send a confirmation email.
Does this work with Let's Encrypt / auto-renewing certificates?
Yes. Even with auto-renewing certificates, renewals can fail silently. Our notifications act as a safety net to catch failed renewals before they cause downtime.
