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.
Amber Worth - PeerSpot reviewer
Retrieves data from quarantines and easy to read logs with robust security features
Some of the searchability when looking for specifics in Exchange logs is tedious. Although eventually the information is located, it can be difficult if detailed information is lacking. Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous. Simplifying interfaces would also be appreciated.

Quotes from Members

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

Pros

"The sanitization is very good."
"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 threat management feature includes policies and alerts that are valuable."
"The security features provided by Microsoft are robust."
"It provides security to both on-premises and Azure infrastructures."
"Online Protection's most valuable feature is its admin interface."
"Microsoft EOP's most valuable feature is a shared mailbox."
"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
"It offers great security against malware and other threats."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
 

Cons

"Although the number of AV engines is good, it could be better."
"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."
"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."
"It would be helpful for customers if Plan 1 features were included with EOP."
"Our company faces difficulty with Microsoft Exchange Online Protection (EOP) because it's too big, clunky, and difficult for a small client to implement quickly and easily."
"The tool's classification for bulk email is cumbersome."
"Microsoft 365 Defender and EOP policies are stable with the proper license. However, with the basic policy, it's hard to say it's stable due to configuration limitations."
"The security compliance features need to be improved. Sometimes, a client's mailbox becomes full because of retained information and not because of mail. I would like to see improvement in block rules as well."
 

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 very expensive, I rate the pricing a six. For licensing, we can make monthly or yearly payments. Right now, we pay 5 USD per month to secure a person's license."
"The product's pricing is competitive for the US market."
"Regarding the price, it's comparable to other service providers. We've also looked at Check Point's offerings, and the pricing doesn't seem to be an issue."
"It is a low-price solution."
"It's a high price."
"The pricing of the solution is reasonable."
"The product is expensive."
"The pricing for the solution depends on what you are trying to achieve with the use of the product, but I know that it is not a cheaply priced product. Yearly payments have to be made towards the licensing fees of the solution."
