Questions fréquentes

Comment obtenir une note A+ ?

Activez TLS 1.3 avec des suites fortes, assurez le secret de transmission complet (PFS), déployez HSTS correctement et utilisez un certificat valide d'une CA de confiance.

Pourquoi ma note est-elle basse avec un certificat valide ?

Le score évalue toute la configuration TLS — protocoles hérités, suites faibles ou absence de HSTS le réduisent.
