SSL Certificate Monitoring
Never let a certificate expire again.
PingWatchdog monitors your SSL/TLS certificates and alerts you before they expire. Know about expiring certs, domain mismatches, and weak cipher suites before they cause outages.
How it works
Add a domain to monitor its SSL/TLS certificate
We check the certificate every 24 hours — issuer, expiry date, subject, SANs
Get notified 30, 14, and 7 days before expiry
See full certificate chain details in your dashboard
Common use cases
SaaS platforms with customer-facing domains that need automated certificate monitoring
Frequently asked questions
How often do you check certificates?
Every 24 hours. We check the full certificate chain, issuer, expiry date, subject, and Subject Alternative Names.
When do you send expiry warnings?
You get alerts at 30 days, 14 days, and 7 days before expiry. You can configure which channels receive SSL alerts separately from uptime alerts.
Does this check for weak ciphers?
Yes — we flag certificates using deprecated algorithms (SHA-1) or weak key sizes. We also alert on domain name mismatches.
