Pros Que es sin lugar a duda una herramienta multiservicios, que permite trabajar eficientemente en todos los programas compatibles como Word, Power Point, y Excel entre otros. Además estos programas se vienen actualizando continuamente, lo que los convierte en herramientas mucho más útiles y agiles. Gracias a este programa el sistema siempre está protegido. Cons Lo único que no me gusta es que cada programa debería traer alguna pauta o tutoría de como usarlos y todas las opciones con las que cuenta cada programa. Claro está para las personas que tienen conocimientos mínimos sobre el tema. Review Source Maria Teresa O.

If you are looking for an endpoint solution that will give you informative, usable data is the platform to go with! Pros The best part about MS Defender hands down is the real time data it gives you in the O365 portal. I was extremely worried about switching to Defender as our endpoint security but so far we couldn't be happier. Whether it's Anti-Phising, Anti-Malware, or Anti-spam, the data it provides has been extremely instrumental in stopping/preventing certain attacks. Cons So far there is nothing about the product itself that I dislike. It would be nice if there were more educational videos on certain areas because it is easy to spin your wheels when attempting to make changes.
