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.

"This product is powerful and quite simple to use."
"Barracuda is good at keeping the garbage from reaching your inbox."

Cons

"Artificial intelligence improvement could be used to help block spam and phishing mail that is directly delivered to users."
"There is room for further integration with the wider platform."
"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."
"We are using the tool’s 400 model which does not offer accurate spam detection. We have also had performance issues with the tool."
"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."
"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."
"The spam filtering is a little too aggressive. You can not get granular enough to back off on 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."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
