Robust email protection with advanced features such as effective spam filtering, virus and malware defense, phishing protection and high scalability
Our customer faced a significant challenge with spam, leading to increased expenses. The complexity of their email infrastructure added to the issue, with some clients using Microsoft Exchange, others relying on different systems, and some operating on Linux platforms. To address this, we…

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is an excellent, intelligent solution that provides maximum security from email attacks."
"Before this solution, we didn't have any separate feature for protecting our emails. We used to only have a firewall but now we have email security. It has a graphical interface and we can see the log every time. We can see that the performance is fine."
"All features it provides on the cloud environment are very, very useful, including the antivirus that is enabled on it."
"One advantage is its immediate deployment capability. So the fast speed to deploy is a big plus point."
"It can effectively combat phishing attacks, block spam, provide confirmation, and ensure operational manageability with a strong focus on product stability."
"Its backups are valuable."
"I appreciate that the product provides account takeover protection."
"The most valuable feature of the Barracuda Email Security Gateway is the ATP."
"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 is the straightforward setup."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"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."
 

Cons

"Sometimes there are false positive emails coming through, so they should improve further on detection technologies and techniques."
"The reports are standard, and it would be nice to be able to customize them."
"We still have critical threats coming into our environment and delivered to our users. When we compare it with other solutions, these other solutions can already detect those threats."
"Barracuda's spam database isn't on par with its competitors. Users complain about the spam email they're receiving, and we report the issue. Barracuda said they are going to update their system to block the malicious email we received, but we're still getting the same spam. The signatures are not in their database. They need to update their spam signatures because spam is bypassing Barracuda."
"There's a bit of configuration work that's needed with the DNS service provider, but other than that, everything else should be very smooth."
"The solution should include an improvised anti-phishing feature, since it blocks certain genuine emails."
"There is room for improvement in the management of multiple domains."
"The downsides of the solution stem from the fact that it is an expensive product, and one may see too many false positives when using it, making them both areas where improvements are required."
"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."
"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."
"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."
"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."
 

Pricing and Cost Advice

"The price of this solution is very high, but it's working fine."
"We find the solution's pricing okay."
"For overall value and cost, Barracuda came in as most appropriate, price as well as services provided. In terms of price, it's average . It's not the most expensive, it's not the least expensive but it works well."
"We pay between $8 and $10 USD per user per month."
"We paid for an annual license."
"It is a cost-effective and relatively cheap solution as compared to others. Our customers have a yearly subscription. We do have a few customers with monthly subscriptions, but they have cloud-based Email protection, which is a different type of solution. Both solutions are very good."
"Barracuda Email Security Gateway is a cost-effective solution."
"We have a long agreement with Barracuda Email Security Gateway. We're very pleased with the cost and the solution. The cost is in the average range for this type of solution."
"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."
"My company makes annual payments towards the licensing costs solution."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"The solution is not expensive."
