Advanced email filtering has blocked massive spam volumes and prevents unauthorized data leaks
Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts. Streamlining this could improve overall usability and security management for users. Reporting is another area needing improvement in Mimecast Advanced Email Security, as the reports provided are not very easy to decipher. With artificial intelligence being integrated into various tools including Mimecast Advanced Email Security, I believe there is potential to enhance functionality, enabling users to ask specific questions and retrieve concise answers instead of overwhelming data. I choose a nine for Mimecast Advanced Email Security because improvements such as better user interface and artificial intelligence integration features would greatly enhance its usability. While no tool is perfect, these adjustments could greatly elevate Mimecast Advanced Email Security's capabilities.

Easy to install and secures users against URL relay attacks, spam, and malicious attachments
The frequency in which this solution receives technical updates should be improved. If they are to be rated as the number one email appliance then they should also be the first to receive updates. It should happen across all of the customers, immeidately. In the next release of this solution, I would like to see more user awareness, such as information about phishing email attacks that have been prevented. The baselining and reporting is better with some of the competing solutions.
