HS
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.
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

"My advice to those considering this product would be to go for it."
"I have always found Mimecast to be very responsive; for example, if we see something come through, they address it and it helps to sort out the issues."
"Email security is the most valuable feature of the solution."
"Mimecast Mailbox Community is an email gateway required for every organization, regardless of size."
"The most valuable feature is the DMARC Analyzer."
"Mimecast is pretty good, even if you're on Office 365."
"The solution's performance is good."
"The security is pretty good, and that's why we're going to upgrade to an even more advanced package. We used it when we had a power issue, and it works. It has been pretty reliable, and the support has been quite good."
"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

"Its pricing can be improved. It is a bit expensive."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult."
"Technical support has been slower than it was in the past, likely due to the pandemic."
"I don't think it's ideally suited for maybe a smaller business environment, like, for example, for companies with less than 100 seats."
"This solution can be frustrating. It blocks many things that should be going through."
"The price could be better, it should be reduced."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"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

"It's an expensive solution."
"The licensing costs are per-user for the product that you get with them."
"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."
"The solution is expensive."
"The product has good pricing in terms of return on investment."
"The price of Mimecast Mailbox Continuity is expensive."
"The customers can select the license packages as per their requirements."
"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."
