Network Engineer at a computer software company with 11-50 employees
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.

Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

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."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"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."
"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 is the straightforward setup."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"Mimecast Mailbox Continuity helps companies continue to move."
"The solution offers good technical support."
"We're now certain business-critical mail is perfectly protected in multiple ways."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"We used Mimecast Mailbox Continuity when we had a power issue, and it works, has been pretty reliable, and the support has been quite good."
"Mimecast Mailbox Community is an email gateway required for every organization, regardless of size."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"My advice to those considering this product would be to go for it."
 

Cons

"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."
"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."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"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 solution is not 100 percent stable and that can use improvement."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"The solution is not 100 percent stable and that can use improvement."
"The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. It retains your email for 45 days. They can maybe increase this duration."
"I don't think it's ideally suited for maybe a smaller business environment, like, for example, for companies with less than 100 seats."
"The filtering needs more flexibility."
"The solution is expensive in comparison to similar solutions."
"The detection rates are an area for improvement."
"The installation is not so straightforward."
"The price of the solution is expensive. It can improve by reducing the price."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves."
