SSL Security Best Practices

Automate Renewals

Forgotten certificates cause downtime. Use Let's Encrypt or professional monitoring to automate the renewal process.

Monitor Transparency

Keep an eye on Certificate Transparency (CT) logs to ensure no unauthorized certificates are issued for your domain.
