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.

Advanced email filtering has blocked massive spam volumes and prevents unauthorized data leaks
Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts. Streamlining this could improve overall usability and security management for users. Reporting is another area needing improvement in Mimecast Advanced Email Security, as the reports provided are not very easy to decipher. With artificial intelligence being integrated into various tools including Mimecast Advanced Email Security, I believe there is potential to enhance functionality, enabling users to ask specific questions and retrieve concise answers instead of overwhelming data. I choose a nine for Mimecast Advanced Email Security because improvements such as better user interface and artificial intelligence integration features would greatly enhance its usability. While no tool is perfect, these adjustments could greatly elevate Mimecast Advanced Email Security's capabilities.

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."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"With both of them working together, we have the perfect solution for mail."
"The most valuable feature is the straightforward setup."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"Its administration console is very easy to use. The administration console is absolutely important because you interact with the platform through it."
"What I like about the integration is that it is directly into Microsoft 365, users can use their Microsoft 365 credentials to log into the portal and access their mail."
"The product is good. To date, we have not faced any challenges."
"Mimecast has been in the market for a long time; it's a good tool if you want to simplify your operations and a good tool for removing on-prem appliances that otherwise you would need to do with the protection that Mimecast provides."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"I have always found Mimecast to be very responsive; for example, if we see something come through, they address it and it helps to sort out the issues."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"The setup was easy."
 

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."
"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."
"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."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"The solution is not 100 percent stable and that can use improvement."
"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 feature that should be included is to remove the block on the encrypted files."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"The interface isn't the best. How everything works on the back end is confusing."
"Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts."
"The installation is not so straightforward."
"The price could be better, it should be reduced."
"We discussed the phishing aspect, the DNS system, and the key rotation."
"As for areas for improvement within Mimecast Web Security, I believe there is quite a lot that can be improved."

"My company makes annual payments towards the licensing costs solution."
"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
