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.

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 a really good product with a lot of features. It is responsive, updated, and modern. It is easy to use and has an easy interface for non-IT users. Its dashboard is also quite fine. It is also quite flexible and has an API at the backend."
"Great at blocking spam."
"It is very simple to whitelist addresses."
"I like Barracuda's cloud sandbox feature."
"For the moment the solution is good."
"The feature that sets Barracuda apart from other solutions is the Office 365 cloud-to-cloud backup."
"Barracuda Email Security Gateway is very simple to use."
"There are plenty of features, such as sandboxing capabilities with zero threat protection. It has all the leading email security appliances compared to other solutions."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"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."
"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."
"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."
 

Cons

"Barracuda should add an option where it can add multiple domains, such as abc.com, bbc.com, and cbc.com; therefore, only these domains' emails will be allowed and other domains' emails will not be relayed through Barracuda Email Security Gateway, whereas if you allow the IP address, then any of the domains' emails will be relayed through Barracuda Email Security Gateway; that is the drawback that I have observed, so Barracuda should work on this."
"There is room for further integration with the wider platform."
"I had some difficulty in the past with the system getting swamped and overwhelmed trying to process all incoming traffic."
"There are limited administration controls that should be improved."
"The reporting can be improved."
"The service best suited for small to medium-sized enterprises, not large enterprise companies."
"Barracuda isn't catching everything. We're still getting quite a few phishing emails, so we're looking for something else."
"Two improvements that are needed include an enhancement in the proxy feature, as well as the ability to more fully automate patches and updates."
"The solution is not 100 percent stable and that can use improvement."
"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."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"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."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"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."
 

Pricing and Cost Advice

"We are using the trial version right now, and before purchasing the license, we need to solve some of the issues that we are facing. We need a proper solution for our email, and then we will look into pricing. We have a vendor for licensing."
"The pricing for the product is fine."
"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."
"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."
"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 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."
"Barracuda has the best price. Every year we need to renew our license, and every year I need to compare Barracuda to two or three other players in the market. Barracuda always has a price that is 30 to 40 percent less than the other players' prices."
"Barracuda Email Security Gateway is a cost-effective solution."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"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."
"The solution is not expensive."
"My company makes annual payments towards the licensing costs solution."
