What Is SSL Monitoring?
SSL certificate monitoring continuously checks the certificates installed on your web servers so they remain valid, trusted, and correctly matched to the requested hostname. Effective certificate management goes beyond installation because automatic renewal can fail after a DNS change, permissions issue, expired credential, or rate limit. Expired certificates, hostname mismatches, and incomplete trust chains can trigger browser warnings that block visitors from your site. Visual Sentinel validates the certificate with every uptime check and sends expiry warnings 13, 3, and 1 day before expiration by default, with optional 20-day and 6-day tiers. It records certificate identity and validity details so you can see when the presented certificate changes and investigate unexpected renewals or issuer changes.
Built for issues
customers actually notice.
Expiry Alerts in Advance
Get default alerts 13, 3, and 1 day before expiry, with optional 20-day and 6-day warning tiers.
Trust and Hostname Validation
A real TLS connection checks whether the certificate is trusted for the requested hostname. Broken or incomplete trust paths fail even though only leaf-certificate details are shown.
Configuration Issue Detection
Detect hostname mismatches, untrusted or incomplete chains, expired certificates, and not-yet-valid certificates.
Continuous Monitoring
SSL is checked alongside every uptime check. No separate tool or subscription needed.
