Secures email by identifying threats and managing email policies effectively
The intuitive management interface feature makes email security policies very easy to implement as it's all about features that need to be enabled or disabled. Our investigation in any incident or mail is very useful as it provides all details about incoming mails, enabling thorough review and detection. The real-time threat intelligence feature is particularly useful as it detects all kinds of threats identified by incoming mails. The Impersonation license utilizes AI tools. Sometimes some phishing mails are reported as phishing, but they are not actually phishing mails. They are detected due to certain words and languages that appear suspicious but were generated by AI tools. Everyone or an advisor may use it for their own purpose or learning, even though it indicates that the mail detected is phishing when it's not.

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

"The anti-spamming and anti-phishing features are great; they're really strong and stable in this solution."
"The most valuable feature of Barracuda Email Security Gateway is that it blocks almost 99 percent of threats from users' email inboxes."
"It can effectively combat phishing attacks, block spam, provide confirmation, and ensure operational manageability with a strong focus on product stability."
"It is a very stable solution."
"We find the product to be scalable."
"It can scale."
"The interface of the Barracuda Email Security Gateway is pretty user-friendly, and you can easily navigate through it."
"We find the email security to be valuable."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"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."
"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 most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"The most valuable feature is the straightforward setup."
 

Cons

"The initial setup can be a little bit complex."
"The reports are standard, and it would be nice to be able to customize them."
"Regarding real-time intelligent features of the Barracuda Email Security Gateway, some spam emails are still being released by the ESG to the end users, so the functionality is not working appropriately."
"We detect some failures in some mails; not all mails pass through consistently. Some mails pass while others are dropped without any apparent logic, despite having the policy set for specific recipients or senders."
"The pricing is a little bit high, and it is causing the company to rethink renewal. If they could lower the pricing, that would be ideal."
"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."
"I would like to have better integration with third-party archival vendors to facilitate moving data in and out."
"There are some times when legit emails are trapped on Barracuda and we are unable to get that information unless we actually log on to the network to find out."
"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 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."
"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."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"The solution is not 100 percent stable and that can use improvement."
 

Pricing and Cost Advice

"The solution is priced low. We have received a good price discount here in Sri Lanka. There are additional licenses we have to purchase a license for the ATP."
"We paid for an annual license."
"Compared to other products, this solution is quite affordable."
"e solution's pricing is exceedingly high, and it continues to increase."
"The pricing for the product is fine."
"The regular pricing was initially very reasonable, but three years ago, Barracuda revised their price list and SKUs, resulting in a significant doubling of the standard prices."
"The licensing fees are part of a bundled support package that we pay for."
"Our licensing fees are approximately $4,000 per year, and this includes updates for the antivirus and spam signatures."
"The solution is not expensive."
"My company makes annual payments towards the licensing costs 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."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
