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.

Offers clear vision on the clear side of what is being blocked and easy to use but a bit old-fashioned GUI
I would rate my experience with the initial setup a four out of ten when one is difficult, and ten is easy. It's difficult initially since it's an on-premise solution. So it's a bit difficult. So the initial assessment took a few days, and then the deployment was a couple of days. It is on-prem. That is also one of the improvements you need to make on the cloud. Most of the people like things to be on the cloud. You don't have the burden of setting up things on-premise.

Quotes from Members

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

Pros

"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."
"Its backups are valuable."
"The link protection and anti-phishing features are great."
"The performance is good."
"I would suggest implementing Barracuda Spam, because this solution has a multi-factor threat analysis engine, which other products don't have."
"The most important features of Barracuda Email Security Gateway are the simple and quick configuration, interactive console, and easy-to-understand logs."
"Barracuda's email service is simple and cost-effective, offering excellent overall protection."
"Barracuda has one of the best email security solutions for SMB and big enterprises."
"I like that it doesn't hold emails for any reason; it sends out notifications to the user as well as administrators. So we have a clear vision on the clear side of what is being blocked and in time as well."
"The product's most valuable features are spam protection and artificial intelligence."
 

Cons

"It's not a scalable product. If we want to scale it then we have to change the device, because it is on-premises."
"There is room for improvement in the speed of the interface, specifically the cloud interface, is a bit slow."
"Some of the phishing emails are not being blocked. Another problem is that we are not able to manage the date and time in our time zone."
"The initial setup can be a little bit complex."
"The user interface needs to be more responsive."
"Barracuda's spam database isn't on par with its competitors. Users complain about the spam email they're receiving, and we report the issue. Barracuda said they are going to update their system to block the malicious email we received, but we're still getting the same spam. The signatures are not in their database. They need to update their spam signatures because spam is bypassing Barracuda."
"There's a bit of configuration work that's needed with the DNS service provider, but other than that, everything else should be very smooth."
"There is room for further integration with the wider platform."
"The technical support services and stability need improvement as well."
"There is room for improvement in GUI because it is a bit old-fashioned."
 

Pricing and Cost Advice

"The price of Barracuda Email Security Gateway is approximately $17 per user annually."
"There is an annual license required for this solution."
"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."
"Barracuda Email Security Gateway is an affordable solution that caters to small, midsize, and high-end businesses with great revenue."
"The licensing cost is competitive, it's not too high and not too low."
"We paid for an annual license."
"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."
"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."
"It is a cost-effective product."
"The pricing is in the middle. Compared to other products, it should be five out of ten, where one is cheap and ten is expensive."
