Provides reliable real-time email protection and offers competitive pricing features
Regarding Kaspersky Security for Mail Server, I have not compared with other solutions, but I will compare and provide feedback. It is a reliable and fast security solution, and I can say it blocks better than other competitor software. Kaspersky Security for Mail Server has support for Windows and Linux, but regarding improvement, I have to dig deep and will have to do research on that. I have not checked into much detail about what can be better in Kaspersky Security for Mail Server. I have checked in general. If given some time, I can check and compare with other solutions. Regarding Kaspersky Security for Mail Server, I have found this is quite a good solution. It has a good response and good detection capability. I have not checked other products, so I cannot give any detailed or specific feedback regarding that. From what I have checked from Kaspersky mail security, it is satisfactory.

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

"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"The sanitization is very good."
"The most valuable feature is called summary reconstruction which is used to deliver encrypted files to users."
"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."
 

Cons

"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"Although the number of AV engines is good, it could be better."
"The DLP should be upgraded and has room for improvement."
"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."
 

Pricing and Cost Advice

"The solution is not expensive."
"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
"My company makes annual payments towards the licensing costs solution."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"According to our customers, the price of MetaDefender is high and it continues to increase by almost 15 percent each year."
