How to Monitor SSL Certificate Expiration with Automated Alerts

Never let an SSL certificate expire again with Domain Lab's intelligent monitoring

Expired SSL certificates cause security warnings, lost trust, and can cost your business thousands in lost revenue. Domain Lab automatically monitors SSL certificates 24/7 and alerts you before expiration, with AI-powered analysis explaining exactly what you need to do.

Why SSL Certificate Monitoring is Critical

Security Warnings Kill Trust

When SSL certificates expire, browsers show scary security warnings to visitors. This immediately damages your credibility and causes potential customers to leave your site.

Lost Revenue

An expired SSL certificate can cause immediate revenue loss. E-commerce sites see up to 90% drop in conversions when security warnings appear. Even a few hours of downtime can cost thousands.

SEO Impact

Google penalizes sites with SSL issues. An expired certificate can hurt your search rankings, making it harder for customers to find you even after the issue is resolved.

Customer Data at Risk

Expired SSL means unencrypted data transmission. Customer information including passwords, payment details, and personal data becomes vulnerable to interception.
