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.

Offers clear vision on the clear side of what is being blocked and easy to use but a bit old-fashioned GUI

I would rate my experience with the initial setup a four out of ten when one is difficult, and ten is easy. It's difficult initially since it's an on-premise solution. So it's a bit difficult. So the initial assessment took a few days, and then the deployment was a couple of days. It is on-prem. That is also one of the improvements you need to make on the cloud. Most of the people like things to be on the cloud. You don't have the burden of setting up things on-premise.

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 features are the anti-phishing and anti-spam capabilities."

"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 most valuable features are the anti-phishing and anti-spam capabilities."

"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."

"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."

"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."

"The most valuable feature is the straightforward setup."

"The primary use case of this solution is to filter emails and only allow the legitimate ones through."

More Kaspersky Security for Mail Server pros

"The product's most valuable features are spam protection and artificial intelligence."

"I like that it doesn't hold emails for any reason; it sends out notifications to the user as well as administrators. So we have a clear vision on the clear side of what is being blocked and in time as well."

Cons

"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."

"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."

"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."

"The solution is not 100 percent stable and that can use improvement."

"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."

"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."

"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."

"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."

More Kaspersky Security for Mail Server cons

"There is room for improvement in GUI because it is a bit old-fashioned."

"The technical support services and stability need improvement as well."

Pricing and Cost Advice

"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."

"The solution is not expensive."

"My company makes annual payments towards the licensing costs solution."

"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."
