Entendiendo los Certificados SSL/TLS
SSL (Secure Sockets Layer) y su sucesor TLS (Transport Layer Security) son protocolos de seguridad utilizados para establecer un enlace cifrado entre un servidor web y un navegador.
Preguntas Frecuentes sobre SSL
¿Qué pasa si mi certificado expira?

Para la mayoría de los sitios web, un certificado estándar DV (Validación de Dominio) es suficiente. Los certificados OV o EV proporcionan mayor confianza para sitios corporativos.
