Aaron Alornyenu - PeerSpot reviewer
Helps us stay compliant, has excellent malware detection, and is stable
The solution helped our organization stay 100 percent compliant with industry standards. MetaDefender Email Security can be set to be very aggressive for identifying attacks. This can be done based on how we want it. If we set it to this level, most of our emails will be blocked because the system will block anything that looks suspicious. We will also need to set the spam severity. This is the severity of everything, including phishing, spoofing, and other types of attacks. I would give the solution's ability to identify attacks a nine out of ten. MetaDefender helps us improve our spam catch rate. Any spam we receive is usually due to user subscriptions. We can specify rules of exclusion to meet our requirements as well. It also detects and blocks the links with suspicious codes. MetaDefender Email Security's multi-scanning capabilities for malware detection work based on how we set the parameters. The solution perfectly detects malware. MetaDefender can identify and disarm emails in zero-day attacks.
Frank Rawson - PeerSpot reviewer
It gives clients peace of mind and helps them educate their users about threats
A few years ago, our team found the implementation to be somewhat challenging. It has gotten easier as we've grown more experienced. The difficulty depends on the expertise of the person doing it. I don't work with Mimecast every day, so it might be more difficult for me than it is for one of my techs who regularly does Mimecast implementations. It requires some specific in-depth product knowledge and an understanding of email solutions. The deployment time varies. In South Africa, it depends on who you use to deploy it. If you use one of Mimecast's local partners, it can take up to two weeks because of their process. However, it's only about four to eight hours of work. After deployment, there isn't much maintenance aside from supporting and educating your customers. Users require constant education on how to use the Mimecast client and release an email that has been blocked.

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 sanitization is very good."
"The most valuable feature is called summary reconstruction which is used to deliver encrypted files to users."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"The product is good. To date, we have not faced any challenges."
"The most valuable feature is the DMARC Analyzer."
"The solution is pretty straightforward to use and easy to set up."
"The initial setup is very straightforward."
"URL inspection works pretty well."
"I would rate Mimecast Email Security a nine out of ten."
"It offers an easy initial setup."
 

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."
"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."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"The solution is very expensive."
"As a user, the user interface of the management console could be upgraded, for example."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"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."
"The detection rates are an area for improvement."
"The installation is not so straightforward."
 

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."
"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 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."
"I'm always going to say the price needs to be lower, but it's reasonable."
"For what it is, the product is overpriced."
"The product price is moderate. I rate the pricing a five out of ten."
"The licensing costs are per-user for the product that you get with them."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
