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 most valuable feature is the Antispam services, which are the basic services of spam device"
"Thanks to Barracuda Email Security Gateway, I have seen increases in productivity and functionality in terms of spam reduction and filtering against different threats, which is a benefit by default."
"This product is powerful and quite simple to use."
"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."
"The most valuable feature of the Barracuda Email Security Gateway is the ATP."
"It can scale."
"Its backups are valuable."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The most valuable feature is the straightforward setup."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"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."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"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."
 

Cons

"The UI could be a little cleaner and require less clicking around in different modules. They give the illusion of a single pane of glass, but as you click around to different products, you're actually being transferred into a different system."
"Barracuda Email Security Gateway should add auto-remediation to improve the solution. Additionally, there are times when we have false positives and our general emails get locked, we have mentioned this to Barracuda."
"There is room for improvement in the speed of the interface, specifically the cloud interface, is a bit slow."
"Solution requires regular checking to ensure it's 'keeping up' with spam."
"The solution should add automatic alerts to the mobile."
"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."
"Barracuda should add an option where it can add multiple domains, such as abc.com, bbc.com, and cbc.com. Therefore, this 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 domain's emails will be relayed through Barracuda Email Security Gateway. That is the drawback that I have observed. So, Barracuda should work on this."
"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."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"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."
"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."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"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."
 

Pricing and Cost Advice

"The licensing fees are part of a bundled support package that we pay for."
"The solution requires a license and we pay annually."
"e solution's pricing is exceedingly high, and it continues to increase."
"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."
"There is an annual license required for this solution."
"As far as advanced email security systems, this product is mid-range on the pricing scale."
"Our licensing fees are approximately $4,000 per year, and this includes updates for the antivirus and spam signatures."
"Barracuda Email Security Gateway is an affordable solution that caters to small, midsize, and high-end businesses with great revenue."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"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."
