Great for email archiving, good search functionality, and bug-free
The deployment was very simple. It was backed into the Global Relay host exchange. We're using it through a company called Global Relay and it's on their server. The deployment is instantaneous. It's across all the emails under the domain. You only need one person to implement it. The product does not require any maintenance.

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.

"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
