# Verify SSL Certificate Setup

An expired or misconfigured SSL certificate breaks your site for every visitor with a scary browser warning. Certificate issues also break API integrations, webhook deliveries, and automated systems that validate certificates strictly. These outages are entirely preventable with regular checks.

The check_ssl skill verifies your SSL certificate is valid, properly chained, and not approaching expiration. It reports the certificate issuer, expiration date, supported protocols, and any chain issues that could cause problems in specific browsers or environments.
