RM
Senior Information Systems Engineer at Liberty Pumps, Inc.
Helpful support, and useful dashboards
They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward. I haven't tried it in a while since then. Since I can't turn it off on a per-user basis, I had to turn it off globally. I have certain exceptions for not doing the sanitization, and how to set those up is not intuitive. It would be useful if there were a better way of doing that. Using digital certificates is hard. It would be better if it used Windows Servers' built-in certificate management.
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.

Quotes from Members

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

Pros

"The most valuable feature of MetaDefender Email Security is the CDR. Customers purchase this solution specifically for data communication, as the other features can be obtained through other technologies that most customers already possess. Therefore, data communication serves as the foundation for the platform."
"The most valuable feature is called summary reconstruction which is used to deliver encrypted files to users."
"The sanitization is very good."
"The reviewer gave Mimecast Email Security a rating of 10 out of 10."
"Mimecast certainly helped my customers reduce phishing emails."
"It does a good job for us, and its admin console is easy to use."
"It offers an easy initial setup."
"It's good, it keeps the spam out."
"The solution is pretty straightforward to use and easy to set up."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."
 

Cons

"They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward."
"The DLP should be upgraded and has room for improvement."
"Although the number of AV engines is good, it could be better."
"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."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data. They charge an extraction fee."
"I'd like to have better support from the product in the future."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"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."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you, but that is, unfortunately, kind of becoming a trend with everything. In terms of features, I haven't had any complaints. However, I don't like the fact they moved to a paid training subscription model. They used to have a lot of free webinars for training, but they have started to charge for them in the past year."
 

Pricing and Cost Advice

"According to our customers, the price of MetaDefender is high and it continues to increase by almost 15 percent each year."
"It's an expensive solution."
"The customers can select the license packages as per their requirements."
"I'm always going to say the price needs to be lower, but it's reasonable."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"The product price is moderate. I rate the pricing a five out of ten."
"It is a bit expensive."
"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."
"For what it is, the product is overpriced."
