Why SSL Matters
SSL/TLS certificates encrypt data in transit and authenticate your website to visitors. Expired or misconfigured certificates can expose your users to attacks and damage trust.
Common SSL Issues
Expired Certificates: Browsers display warnings, driving visitors away.
Incomplete Chain: Missing intermediate certificates cause trust errors.
Weak Protocols: Support for outdated TLS versions creates vulnerabilities.
Hostname Mismatch: Certificate doesn't match the domain being accessed.
