My Email Communications Security Assessment (MECSA)

CONFIDENCIALIDAD EN EL ENVÍO/RECEPCIÓN

(5.0/5)

Tu proveedor de correo utiliza cifrado para proteger la confidencialidad de tus mensajes (enviados/recibidos). Utiliza las últimas tecnologías disponibles, asegurando la identidad de los servidores con los que interactúa.

PHISHING Y IDENTITY THEFT

(3.5/5)

Tu proveedor de correo electrónico detecta la recepción de mensajes enviados desde servidores no legítimos. También toma medidas para evitar que servidores no autorizados envíen correos electrónicos en su nombre. Con estas acciones, se reduce drásticamente la probabilidad de recibir (o generar) suplantación y/o ataques de phishing.

INTEGRIDAD DE LOS MENSAJES

(3.5/5)

Tu proveedor de correo electrónico puede identificar mensajes recibidos que han sido modificados o interceptados durante el trayecto entre emisor y receptor.
