Pricing that is competitive, excellent technical support, and email security
They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried. They are very easy to use. We don't have as many problems with email security. They have some areas that could be improved. For example, we also use Zix email Encryption for email encryption, which was clunky and could be improved, but the email security itself has been excellent.

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

"They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried."
"They are very easy to use."
"It's easy to use and user-friendly. Users can also easily release spam emails."
"My advice for others looking into using Mimecast Advanced Email Security is that they can strengthen their security very well if they choose to go with it."
"URL inspection works pretty well."
"The solution is stable and reliable; there are no bugs or glitches, and it doesn't crash or freeze."
"The security on offer is very good."
"The initial setup is easy."
"Mimecast Mailbox Community is an email gateway required for every organization, regardless of size."
"I have been satisfied with Mimecast Email Security as a good solution."
"It is our spam filter, phishing filter, and executive impersonation filter."
 

Cons

"It needs to make sure that the application is up to date with new attacks. They should also send us the demo or introductions for their new incoming features."
"Email security checks contain a small number of false positives."
"Technical support is no longer as good as it once was."
"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."
"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."
"It analyzes patterns but sometimes overlooks suspicious indicators."
"The product's interface could be improved to be more user-friendly."
"The interface isn't the best. How everything works on the back end is confusing."
"The solution is complex and not easy to use."
"The attachment scanning feature doesn't work properly."
"The detection rates are an area for improvement."
 

Pricing and Cost Advice

"They're fairly inexpensive, but they're right in the ballpark of most of the other online products like that."
"I can rate it five out of ten because there are different platforms that also offer the same services for lower prices. But AppRiver is more flexible."
"The price of Mimecast Mailbox Continuity is expensive."
"The customers can select the license packages as per their requirements."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."
"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."
"The product has good pricing in terms of return on investment."
