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 anti-spamming and anti-phishing features are great; they're really strong and stable in this solution."
"The solution's anti-spam features are its most valuable aspect."
"Barracuda's email service is simple and cost-effective, offering excellent overall protection."
"Barracuda Email Security Gateway is very simple to use."
"I appreciate that the product provides account takeover protection."
"The most valuable feature of Barracuda Email Security Gateway is that it blocks almost 99 percent of threats from users' email inboxes."
"The interface of the Barracuda Email Security Gateway is pretty user-friendly, and you can easily navigate through it."
"Eliminating inbox clutter creates an opportunity to be more productive instead of wasting time manually sorting through spam."
"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

"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."
"Artificial intelligence improvement could be used to help block spam and phishing mail that is directly delivered to users."
"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."
"Sometimes the spam filtering is a little too aggressive. You can not get granular enough to back off what is considered spam and what is not."
"Barracuda Email Security Gateway can improve reporting and anti-spam. The anti-spam engine is not working well. We are seeing a lot of problems where spam is going through the gateway. Additionally, access privilege should be given to the IT support, because they don't have a lot of privileges. We are forced to give our IT support administrative access in order to clear and deliver emails and this should not be happening."
"This product can always be made more secure."
"Two improvements that are needed include an enhancement in the proxy feature, as well as the ability to more fully automate patches and updates."
"We still have critical threats coming into our environment and delivered to our users. When we compare it with other solutions, these other solutions can already detect those threats."
"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

"Barracuda Email Security Gateway is a cost-effective solution."
"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."
"The price of this solution is very high, but it's working fine."
"We have a long agreement with Barracuda Email Security Gateway. We're very pleased with the cost and the solution. The cost is in the average range for this type of solution."
"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."
