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

"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."
"Mimecast is pretty good, even if you're on Office 365."
"The product is good; to date, we have not faced any challenges."
"In terms of technical superiority and the product itself, there are no complaints."
"The setup was easy."
"I recommend Mimecast based on customer requirements and budget."
"The solution's performance is good."
"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."
"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

"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 needs to reduce the number of false positive emails; a big pain point for us."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"The installation is not so straightforward."
"The detection rates are an area for improvement."
"The filtering needs more flexibility."
"While it's quick and easy, the initial setup could be more user-friendly."
"The price could be better, it should be reduced."
"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

"I'm always going to say the price needs to be lower, but it's reasonable."
"For what it is, the product is overpriced."
"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 price of Mimecast Mailbox Continuity is expensive."
"It is a bit expensive."
"The product has good pricing in terms of return on investment."
"The solution is expensive."
"The product price is moderate. I rate the pricing a five out of ten."
