SSL certificate expiry monitoring that actually warns you in time
Expired certificates break trust: browsers warn users, conversions drop, and APIs fail TLS handshakes. SitePuls tracks certificate not-after dates and reminds you at 30, 14, and 7 days—by email or Telegram—so renewals stay boring.
Why expiry is a product problem, not just IT trivia
HTTPS is the default. When a cert lapses, users see scary screens; automated integrations may fail outright. Monitoring expiry is part of keeping services reachable.
Why spreadsheets and calendar nudges fail
Teams change, handoffs slip, and CA reminder emails land in junk. A monitor tied to the hostname keeps the date next to your other incidents.
What SitePuls checks
The certificate presented for your hostname, counting down to expiration. It’s not a replacement for your CA’s billing—but it is an operational backstop.
Alert workflows that fit small teams
Send reminders to whoever owns DNS or hosting. Pair with website monitors so you correlate user-facing errors with cert timelines.
Agencies and many hostnames
Each client site may use different registrars and CDNs. Central reminders reduce the risk that one renewal thread gets lost.
Relation to domain monitoring
Domains and certificates expire on different clocks. Track both: a paid domain with a lapsed cert still hurts; a valid cert on an expired domain helps no one.
Relation to website uptime
HTTP monitors catch many failures; SSL monitors catch the specific “about to expire” class before it becomes an outage.
What SitePuls doesn’t do
Automatic renewal inside your CA account, CT log analytics, or deep TLS cipher auditing—SitePuls focuses on clear expiry visibility and alerts.
FAQ
When do alerts fire?
At 30, 14, and 7 days before expiration by default—tune to your process.
Does it work with Let’s Encrypt short-lived certs?
Yes—the countdown follows the actual not-after date.
Wildcard certificates?
Add monitors for hostnames as clients reach them; each connection is evaluated on its own.
Notification channels?
Email and Telegram for SSL reminders, consistent with other monitors.
Is this different from /ssl-monitoring?
Same product area—this page focuses on expiry-intent searches; the feature set is the SSL monitor in SitePuls.
Can I combine with API monitoring?
Yes—HTTPS APIs benefit from both response checks and expiry tracking.
Will I get alerted on mis-issued certs?
If the served certificate chain breaks handshakes, your HTTPS monitors will show failures; expiry monitoring targets dates.
How do I add a monitor?
Create an SSL monitor for the hostname, attach contacts, and let SitePuls poll on schedule.
