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

"By choosing Barracuda as our solution for filtering, year by year we have seen a big improvement in our environment with a significant reduction in the number of threats."
"It catches a lot of things and has the ability to add domains as well as add senders and update their things."
"The product safeguards user mail for gateway defense, data protection, business continuity, AI-based inbox defense, and automated threat detection and incident response."
"This appliance has helped in that we now eliminate the thousands of scams, spam, and malware emails that are destined for our users."
"The solution helps us to block some blacklisted emails."
"The most valuable feature of the Barracuda Email Security Gateway is the cloud ATP functionality not available on the on-premise version. Most of the zero-day attacks can be mitigated with ATP. Additionally, the reporting functionality is good."
"The complete filtering feature for all of the emails is valuable for us, as there are lots of attacks that come to our network through emails and it does a good job of blocking them."
"We find the product to be scalable."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"The most valuable feature is the straightforward setup."
"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."
"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."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"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

"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."
"One aspect of the product that can be improved is the availability of support."
"Sometimes the spam filtering is a little too aggressive. You can not get granular enough to back off what is considered spam and what is not."
"The pricing of this solution could be improved."
"Some customers experience issues with integration."
"Barracuda Email Security Gateway can improve reporting and anti-spam. The anti-spam engine is not working well. We are seeing a lot of problems where spam is going through the gateway. Additionally, access privilege should be given to the IT support, because they don't have a lot of privileges. We are forced to give our IT support administrative access in order to clear and deliver emails and this should not be happening."
"The solution should include an improvised anti-phishing feature, since it blocks certain genuine emails."
"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."
"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."
"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."
"The solution is not 100 percent stable and that can use improvement."
"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."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
 

Pricing and Cost Advice

"We paid for an annual license."
"Compared to other products, this solution is quite affordable."
"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."
"The price of the solution should be reduced. The price in the USA is less than where we are. Our local distributor of the solution is manipulating the market."
"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."
"The price of Barracuda Email Security Gateway is approximately $17 per user annually."
"We pay between $8 and $10 USD per user per month."
"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."
