About

The SSL Certificate Expiry Alert tool monitors your domains and sends notifications before certificates expire. Configure alert thresholds from 7 to 90 days and receive color-coded urgency levels — expired (red), critical (red), high (orange), medium (amber), and safe (green). This proactive monitoring prevents costly service outages caused by expired SSL certificates.

The alert system tracks all your monitored domains in one dashboard, showing exactly how many days remain until each certificate expires. Combined with the Expiry Calculator and Renewal Planner tools, you can build a complete certificate lifecycle management workflow that ensures no certificate ever expires unexpectedly.

How to Use

1Add domains to the Certificate Monitor to enable expiry tracking
2Set your preferred alert threshold (7, 14, 30, 60, or 90 days before expiry)
3View the alerts dashboard showing certificates color-coded by urgency level
4Click any certificate to view detailed expiry information and initiate renewal

Use Cases

•Production Monitoring: Continuously track certificate expiry across all production domains to prevent unexpected outages
•Multi-Team Coordination: Share expiry visibility with DevOps, security, and compliance teams to ensure timely renewals
•Compliance Requirements: Meet regulatory requirements for certificate lifecycle management in PCI DSS, HIPAA, and SOC 2 environments
•Vendor Management: Track certificates issued by third-party vendors or managed services that you do not directly control
•Disaster Prevention: Avoid the costly downtime and reputation damage caused by expired SSL certificates on customer-facing services

Tips & Best Practices

•Set a 30-day threshold for standard domains and 60-90 days for critical production systems
•Combine alerts with auto-renewal (Let's Encrypt) for hands-free certificate management
•Monitor certificates from all Certificate Authorities, not just one — different CAs have different renewal processes
•Set up multiple notification channels (email, webhook, Slack) for critical certificate expiry alerts

Frequently Asked Questions

We recommend 30 days for standard domains, 60 days for production systems with complex renewal processes, and 90 days for enterprise environments requiring change management approvals. This gives ample time to renew certificates and test deployment without rushing.

When an SSL certificate expires, browsers display security warnings to visitors, blocking access to your site. This causes immediate traffic loss, damages brand trust, and can affect SEO rankings. Automated monitoring prevents this by alerting you well before expiry.

Yes, the alert system monitors all certificates stored in your account regardless of the Certificate Authority. This includes Let's Encrypt, ZeroSSL, DigiCert, and any other CA certificates you have imported or are actively monitoring.
