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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The Large File Send feature comes in handy when you have to send fairly large attachments."
"I recommend Mimecast based on customer requirements and budget."
"Mimecast certainly helped my customers reduce phishing emails."
"The positive impact of Mimecast Advanced Email Security on our organization is evident in how it has drastically reduced spam emails and improved our data security."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."

"It offers an easy initial setup."
"It's good, it keeps the spam out."
"The technical support services are excellent."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
"The solution provides protection with its Email Track Records and Machine Manual features."
 

Cons

"The differentiation between bulk spam mail and campaign-related mail could be improved."
"The price could be better, it should be reduced."
"I don't think it's ideally suited for maybe a smaller business environment, like, for example, for companies with less than 100 seats."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you about the problem you're reporting."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"The product's interface could be improved to be more user-friendly."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
"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."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"The product's pricing could be more flexible."
"The solution's pricing could be improved."
