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 performance is good."
"The feature that sets Barracuda apart from other solutions is the Office 365 cloud-to-cloud backup."
"This appliance has helped in that we now eliminate the thousands of scams, spam, and malware emails that are destined for our users."
"We find the product to be scalable."
"This solution has helped to significantly reduce the amount of junk email that we receive."
"It is lightweight, and we can filter all of our inbound and outbound emails. We have controls for rate control, quarantine, and tagging. We can see whether an email is a spam email or a phishing email."
"The most valuable feature of Barracuda Email Security Gateway is the complete capabilities it provides. Additionally, the phishing security and sandbox features are effective."
"It can effectively combat phishing attacks, block spam, provide confirmation, and ensure operational manageability with a strong focus on product stability."
"The product's most valuable features are spam protection and artificial intelligence."
"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."
 

Cons

"I have noticed that it takes a little time to get familiar with after deploying and some tweaks need to be done as things come up."
"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 deep scanning feature needs to be improved."
"The initial setup can be a little bit complex."
"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."
"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 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."
"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 GUI because it is a bit old-fashioned."
"The technical support services and stability need improvement as well."
 

Pricing and Cost Advice

"The pricing for the product is fine."
"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."
"There is an annual license required for this solution."
"We pay between $8 and $10 USD per user per month."
"We find the solution's pricing okay."
"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."
"Our licensing fees are approximately $4,000 per year, and this includes updates for the antivirus and spam signatures."
"The price of Barracuda Email Security Gateway is approximately $17 per user annually."
"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."
"It is a cost-effective product."
