The extension automates the tedious task of manually checking SSL statuses for multiple domains. It is particularly useful for agencies or freelancers managing a large portfolio of client sites.
Automated Monitoring: Automatically scans all connected child sites for SSL status at user-defined intervals.
Expiration Alerts: Sends email notifications when a certificate is nearing its expiration date.
Bulk Overview: Provides a dedicated dashboard with a sortable table showing:
Common Name: The domain name associated with the SSL.
Issuer: Who provided the certificate (e.g., Let’s Encrypt, DigiCert).
Validity Dates: Start and end dates for the current certificate.
Days Remaining: A countdown to expiration.
Status Indicators: Visual cues (health icons) on the “Manage Sites” screen to quickly identify sites with SSL issues.

| Notification Threshold | User-defined “days before expiry” (e.g., 30, 15, or 7 days) to trigger an alert. |

| Certificate Details | Deep-dive view for specific sites including Serial Number, Signature Algorithm, and Version. |
| Compatibility | Works with all certificate types, including Let’s Encrypt, Wildcard, and commercial SSLs. |
