Preguntas frecuentes
¿Cómo consigo una A+?
Habilita TLS 1.3 con cifrados fuertes, garantiza PFS completa, despliega HSTS correctamente y usa un certificado válido de una CA de confianza.
¿Por qué mi nota es baja con un certificado válido?
La nota evalúa toda la configuración TLS: protocolos antiguos, cifrados débiles o falta de HSTS la reducen.
