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.
This is a dud product with inferior spam filtering
This is a dud product with inferior spam filtering versus alternatives like SpamHero, and the continuity feature is essentially marketing fluff. Failed deliveries, for example, they don't count it as an issue so those messages won't be queued for another delivery attempt. As I understand it from talking to their support, if the server pings or sends any response at all, then Mail Assure will not keep a copy. It will also weirdly mark messages during that outage as rejected, so it's not like Mail Assure doesn't know that the message never reached the user(s).

Quotes from Members

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

Pros

"The solution's performance is good."
"My advice to those considering this product would be to go for it."
"The solution offers good technical support."
"If you want the ease of use, then Mimecast, or at least a cloud solution, is the way to go."
"What I like about the integration is that it is directly into Microsoft 365, users can use their Microsoft 365 credentials to log into the portal and access their mail."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
"I have been satisfied with Mimecast Email Security as a good solution."
"It offers an easy initial setup."
"The only benefit from Mail Assure is its white label feature and its per-user licensing plus the ability to package archiving and spam protection into a single interface."
 

Cons

"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"This solution can be frustrating. It blocks many things that should be going through."
"As a user, the user interface of the management console could be upgraded, for example."
"The interface and the documentation could be improved."
"Mimecast Email Security is somewhat expensive compared to the competition in the Indian market, and the local presence is lacking as they do not have a local representative currently."
"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."
"The installation is not so straightforward."
"The solution is expensive in comparison to similar solutions."
"This is a dud product with inferior spam filtering versus alternatives like SpamHero, and the continuity feature is essentially marketing fluff."
 

Pricing and Cost Advice

"For what it is, the product is overpriced."
"The price of Mimecast Mailbox Continuity is expensive."
"The solution is expensive."
"The product price is moderate. I rate the pricing a five out of ten."
"The customers can select the license packages as per their requirements."
"The product has good pricing in terms of return on investment."
"It's an expensive solution."
"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."
