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.
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

"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"The most valuable feature is the straightforward setup."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"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 feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
"We like the holding facility that is available for potentially suspicious URL's. This allows a real-time review to be performed before the email reaches a users inbox."
"It is scalable."
"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."
"The email policy configuration options in Microsoft EOP are satisfactory."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."
 

Cons

"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"The solution is not 100 percent stable and that can use improvement."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"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."
"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."
"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."
"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."
"The solution needs to improve its backup."
"The tool's classification for bulk email is cumbersome."
"The solution must improve the user experience."
"When you're using a Microsoft product solution, you can scale it, but if you're not, there are 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."
"It doesn't protect against everything. We do need protection for, for example, endpoints."
"The tool is not 100% stable."
"Performance and speed should continue to be improved."
