Certificate validity
Detect whether the certificate is trusted and valid for visitors instead of waiting for browser warnings or customer reports.
Feature
SSL Certificate Monitoring
NorthDuty checks SSL certificate health as part of uptime and website health monitoring, helping teams catch trust and expiry issues before visitors run into browser warnings.
Monitor SSL issues before they affect visitors
An expired or invalid SSL certificate can make a healthy website look broken to customers. Browsers may block access, visitors may lose trust, and campaigns or customer workflows can stop even when the server is otherwise online.
NorthDuty includes SSL certificate checks inside the same website health run that tracks HTTP status, DNS, redirects, blank pages, broken resources, JavaScript errors, and first-party API calls.
What SSL certificate monitoring covers
SSL is one trust signal inside a broader health check, so teams can see certificate problems in context.
Expiry awareness
Keep SSL expiry visible alongside uptime and health results so renewal issues do not become surprise incidents.
Website health context
Review SSL health together with HTTP status, DNS, redirects, page rendering, resources, JavaScript, and API calls.
Critical route coverage
Monitor the pages where certificate problems would hurt most: homepage, pricing, checkout, signup, login, and campaign pages.
Why SSL monitoring matters
SSL problems can stop visitors before they ever reach the page experience you built.
- Reduce the chance of expired-certificate incidents
- Catch visitor trust problems before they affect campaigns or customer access
- Keep SSL health visible in the same workflow as uptime and page health
- Protect checkout, login, signup, and lead-generation paths
- Avoid discovering certificate issues through customer complaints
