SSL Certificate Monitoring
Never let an expired certificate break.
An expired SSL certificate turns your website into a browser warning page overnight. Pulsewise continuously monitors your certificates, tracks expiry dates, and alerts you well before anything expires — so your visitors never see a security error.
Start Free TrialAn expired certificate shuts your site down
When your SSL certificate expires, browsers don't just warn visitors — they actively block them from reaching your site. Chrome, Firefox, and Safari all display a full-screen security error that most users will never click through. Your site is effectively offline.
Auto-renewal isn't a safety net. DNS changes break validation, server migrations drop certificates, multiple subdomains use different expiry dates, and team turnover loses institutional knowledge. Without monitoring, you're one forgotten renewal from an outage.

NET::ERR_CERT_DATE_INVALID
Attackers might be trying to steal your information from yoursite.com.
We monitor the full health of your certificate
Expiry dates are just the beginning. Pulsewise checks the full certificate chain from your domain certificate through every intermediate to the root authority. If any link in that chain has an issue, you'll know about it before your visitors do.
Staged notifications at 30, 14, and 7 days before expiry give you plenty of time to act. Every certificate change is detected with a clear before-and-after comparison — whether it's an expected renewal or an unauthorized certificate swap.
