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.

Quotes from Members

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

Pros

"The protection from Barracuda Email Security Gateway is essentially a sandboxing solution."
"The most valuable feature of the Barracuda Email Security Gateway is the ATP."
"This product is powerful and quite simple to use."
"The most valuable feature of Barracuda Email Security Gateway is the complete capabilities it provides. Additionally, the phishing security and sandbox features are effective."
"The security protection is the best and it's GUI is user-friendly."
"The anti-spamming, anti-fishing features are great."
"The solution is scalable."
"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."
"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 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."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"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."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
 

Cons

"There is room for further integration with the wider platform."
"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."
"False positives have given us issues."
"Its integration with other solutions can be improved. There should be integration for telemetry information, system information, and other types of information with other solutions. Barracuda currently doesn't have that. Barracuda has its own platform. Its integration with firewalls is quite good, and it communicates really well with firewalls, but I have not seen any other integration. Based on what I know, it does have an API at the backend, but I have not used it."
"Sometimes there are false positive emails coming through, so they should improve further on detection technologies and techniques."
"The initial setup can be a little bit complex."
"The scalability needs improvement, it's the only feature that is required."
"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 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."
"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."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"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."
"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 solution is not 100 percent stable and that can use improvement."
 

Pricing and Cost Advice

"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 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."
"e solution's pricing is exceedingly high, and it continues to increase."
"We typically purchase a one or three-year license for Barracuda Email Security Gateway."
"We pay between $8 and $10 USD per user per month."
"Our licensing fees are approximately $4,000 per year, and this includes updates for the antivirus and spam signatures."
"As far as advanced email security systems, this product is mid-range on the pricing scale."
"The pricing for the product is fine."
"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 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."
