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

"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"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."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"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."
"With both of them working together, we have the perfect solution for mail."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"The product is good; to date, we have not faced any challenges."
"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."
"The initial setup is easy."
"Its administration console is very easy to use. The administration console is absolutely important because you interact with the platform through it."
"I recommend Mimecast based on customer requirements and budget."
"The solution's performance is good."
"The reviewer gave Mimecast Email Security a rating of 10 out of 10."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
 

Cons

"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."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"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."
"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."
"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."
"I'd like to have better support from the product in the future."
"The solution is expensive in comparison to similar solutions."
"The interface and the documentation could be improved."
"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."
"As a user, the user interface of the management console could be upgraded, for example."
"We discussed the phishing aspect, the DNS system, and the key rotation."
"It was not a good experience due to the fact that our main infrastructure had a problem for that entire time."
"The price could be better, it should be reduced."
 

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."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"My company makes annual payments towards the licensing costs solution."
"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."
"The product price is moderate. I rate the pricing a five out of ten."
"The solution is expensive."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The licensing costs are per-user for the product that you get with them."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"The price of Mimecast Mailbox Continuity is expensive."
"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."
