SSL Certificate Best Practices
Monitor expiry dates
Set alerts 30, 14, and 7 days before expiry. An expired certificate causes browser warnings that immediately destroy user trust.
Automate renewal
Use Let's Encrypt with certbot for automatic renewal. If using commercial certs, set calendar reminders and consider multi-year purchases.
Use TLS 1.2+
Disable TLS 1.0 and 1.1. Only allow TLS 1.2 and 1.3. Older protocols have known vulnerabilities that automated scanners will flag.
Check the full chain
Ensure your server sends the complete certificate chain including intermediates. Missing chain certificates cause trust errors on some devices.

Understanding SSL Certificates
What is an SSL Certificate?
SSL (Secure Sockets Layer) certificates encrypt the connection between a user's browser and your server. They ensure data transmitted (passwords, credit cards, personal info) cannot be intercepted. Modern certificates actually use TLS (Transport Layer Security) but the term "SSL" persists.

What happens when a certificate expires?
Browsers display a full-page warning that your site is "Not Secure" or "Your connection is not private." Most users will immediately leave. Search engines may also temporarily deindex your site. Certificate expiry is one of the most preventable causes of downtime.

Types of SSL Certificates
DV (Domain Validation): Verifies domain ownership only. Fastest to issue. Used by Let's Encrypt.
OV (Organization Validation): Verifies organization identity. Shows company name in certificate details.
EV (Extended Validation): Highest level of verification. Required for some compliance standards.
