SSL certificate monitoring & expiry alerts
✓ Automatic SSL checks ✓ Expiry alerts ✓ HTTPS monitoring ✓ Keep secure sites online
Track SSL/TLS certificate expiry with UptimeFlux. Our SSL monitoring warns you before certificates expire—so you avoid HTTPS outages, browser warnings, and trust-breaking security issues.
Why monitor SSL certificates?
An expired SSL certificate can make your site unreachable over HTTPS, trigger browser security warnings, and erode user trust. SSL certificate monitoring helps you renew on time and keep encrypted traffic flowing.
Alerts before expiry
Get downtime alerts 30, 15, and 7 days before expiry so you can renew on schedule.
Avoid HTTPS outages
Keep sites reachable over HTTPS with continuous 24/7 monitoring.
Security posture
Ensure certificates stay valid so visitors see a trusted, encrypted connection.
HTTPS + HTTP checks
Pair certificate checks with HTTP monitoring for full coverage of your secure endpoints.
How SSL monitoring works
UptimeFlux connects to your HTTPS domains and inspects the presented certificate to:
- Read the certificate expiry date
- Calculate days remaining until expiry
- Send alerts at 30, 15, and 7 days before expiry
- Continuously verify certificate validity
SSL monitoring complements our website monitoring for complete HTTPS service visibility.
Which SSL certificates can you monitor?
UptimeFlux supports all common SSL/TLS certificate types:
- Let’s Encrypt certificates
- Commercial CAs (DigiCert, GlobalSign, and more)
- Self-signed certificates
- Wildcard certificates (*.example.com)
- Multi-domain (SAN) certificates
On the free plan (up to 20 monitors) or a paid plan, you can watch SSL expiry and get alerts before certificates lapse.
