Email Security Engineer at Logic Infosecurity
Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Cons

"They could provide a unified licensing model, including all the security features."
"The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. It retains your email for 45 days. They can maybe increase this duration."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data."

"For what it is, the product is overpriced."
