Helps us reduce phishing email attacks and has a user-friendly dashboard
It is the best product. It helps reduce spam and phishing attacks. It has user-friendly Real-Time Phishing Mitigation features for environmental protection. It primarily focuses on verifying security features like SPS (Sender Policy Framework) and Smart DKIM (DomainKeys Identified Mail). The DLP feature ensures that only emails meeting the required security standards pass through the secure gateway. The configuration and management of the policies and settings are easy to navigate. I rate it an eight out of ten.

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.

Quotes from Members

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

Pros

"The solution is easier to manage than FortiMail. You can implement policies easily."
"It helps reduce spam and phishing attacks."
"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."
 

Cons

"Its pricing could be affordable."
"The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very quickly."
"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."
"Although the number of AV engines is good, it could be better."
"The DLP should be upgraded and has room for improvement."
 

Pricing and Cost Advice

"Email Security Gateway's pricing is good."
"According to our customers, the price of MetaDefender is high and it continues to increase by almost 15 percent each year."
