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.

Provides valuable security features and has a straightforward setup process
The initial setup process is straightforward and takes a weekend at most. A .com domain can take up to forty-eight hours, while a local domain takes about four to eight hours because it has to propagate through the international DNS records. It is a cloud-only solution. If you're managing email security on-premises, you use your bandwidth to download emails, including spam, and then use your servers to clean it up. For example, say a third of your email is spam; this consumes significant bandwidth and resources. However, if you use Mimecast, they filter the emails on their servers before delivering them to you. It can be a major selling point in regions with expensive bandwidth, such as Africa. You can save bandwidth and improve overall efficiency by offloading the spam filtering to Mimecast.

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 feature is the straightforward setup."
"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."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"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."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"We like the content filtering and secure messaging features."
"I recommend Mimecast based on customer requirements and budget."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"The interface of this solution is very easy to navigate and user-friendly. There is no delivery in email and other communications, making it reliable. The configuration is relatively easy."
"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."
"It offers an easy initial setup."
"The product is good. To date, we have not faced any challenges."
 

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."
"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."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to 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."
"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."
"The solution is not 100 percent stable and that can use improvement."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data. They charge an extraction fee."
"We discussed the phishing aspect, the DNS system, and the key rotation."
"They could provide a unified licensing model, including all the security features."
"The tool can be challenging because it relies on rule-based configurations, especially for addressing impersonation threats. This approach requires setting up numerous rules to ensure filtering. It should work based on behavior-based analytics."
"The product's interface could be improved to be more user-friendly."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you, but that is, unfortunately, kind of becoming a trend with everything. In terms of features, I haven't had any complaints. However, I don't like the fact they moved to a paid training subscription model. They used to have a lot of free webinars for training, but they have started to charge for them in the past year."
"Its pricing can be improved. It is a bit expensive."
 

Pricing and Cost Advice

"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."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"For what it is, the product is overpriced."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The solution is expensive."
"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 product price is moderate. I rate the pricing a five out of ten."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
