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

"The client has the option to blacklist or whitelist any email address or domain based on the sender and recipient filters. If they want, they can restrict any IP addresses so email won't be received from those IP addresses."
"One advantage is its immediate deployment capability. So the fast speed to deploy is a big plus point."
"It catches a lot of things and has the ability to add domains as well as add senders and update their things."
"All features it provides on the cloud environment are very, very useful, including the antivirus that is enabled on it."
"The most valuable feature is the Antispam services, which are the basic services of a spam device."
"Barracuda has one of the best email security solutions for SMB and big enterprises."
"This solution has helped to significantly reduce the amount of junk email that we receive."
"The anti-spamming and anti-phishing features are great; they're really strong and stable in this solution."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"The most valuable feature is the straightforward setup."
"With both of them working together, we have the perfect solution for mail."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"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."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
 

Cons

"The UI could be a little cleaner and require less clicking around in different modules."
"The solution should include an improvised anti-phishing feature, since it blocks certain genuine emails."
"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."
"I would like to have better integration with third-party archival vendors to facilitate moving data in and out."
"Barracuda should have a sandbox feature in the appliances."
"The pricing of this solution could be improved."
"Barracuda Email Security Gateway can improve email detection. We have some emails that are bypassing the threat scanning. There are some impersonation emails passing through."
"This product can always be made more secure."
"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."
"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."
"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 solution is not 100 percent stable and that can use improvement."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
 

Pricing and Cost Advice

"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."
"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."
"We paid for an annual license."
"Barracuda Email Security Gateway is a cost-effective solution."
"There is an annual license required for this solution."
"Barracuda Email Security Gateway is an affordable solution that caters to small, midsize, and high-end businesses with great revenue."
"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."
"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."
"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."
"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."
