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

"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."

"With both of them working together, we have the perfect solution for mail."

"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."

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

"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 integration rate is very high in Kaspersky, which is why most of our customers like it."

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

More Kaspersky Security for Mail Server pros

"Mimecast Mailbox Continuity helps companies continue to move."

"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."

"The solution's performance is good."

"It is our spam filter, phishing filter, and executive impersonation filter."

"The platform's most valuable features are journaling and email archiving, effectively stopping phishing attacks."

"The initial setup is very straightforward."

"URL inspection works pretty well."

"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."

More Mimecast Email and Collaboration Threat Protection pros

Cons

"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."

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

"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."

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

"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."

More Kaspersky Security for Mail Server cons

"This solution can be frustrating. It blocks many things that should be going through."

"The interface and the documentation could be improved."

"The feature that should be included is to remove the block on the encrypted files."

"The attachment scanning feature doesn't work properly."

"They could provide a unified licensing model, including all the security features."

"I don't think it's ideally suited for maybe a smaller business environment, like, for example, for companies with less than 100 seats."

"We discussed the phishing aspect, the DNS system, and the key rotation."

"The lock in is very, very tight. It is impossible to move out of Mimecast to a different product, like Proofpoint or 365 ATP, and keep the chain of custody for every email that I've archived."

More Mimecast Email and Collaboration Threat Protection cons

Pricing and Cost Advice

"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."

"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."

"For what it is, the product is overpriced."

"I'm always going to say the price needs to be lower, but it's reasonable."

"The product has good pricing in terms of return on investment."

"It is a bit expensive."

"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."
