SSL Certificate Management
SSL/TLS certificate management encompasses the full lifecycle of digital certificates bound to domain names: issuance, installation, renewal, revocation, and auditing. Certificates prove domain ownership to browsers and encrypt traffic between users and servers; an expired or misconfigured certificate causes immediate trust warnings and traffic loss. Modern certificate management leverages the ACME protocol (used by Let's Encrypt) for automated issuance and 90-day renewal cycles, often integrated into hosting platforms, CDNs, or [[api-domain-management|API pipelines]]. For organizations with many domains, centralized management tools track certificate expiry dates alongside domain registrations, ensuring that [[domain-monitoring|domain monitoring]] covers both layers of the domain lifecycle.
Example
Using Certbot with a cron job, your server automatically renews the Let's Encrypt certificate for yourdomain.com every 60 days, eliminating the risk of a browser 'Your connection is not private' warning.
