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 is a dud product with inferior spam filtering
This is a dud product with inferior spam filtering versus alternatives like SpamHero, and the continuity feature is essentially marketing fluff. Failed deliveries, for example, they don't count it as an issue so those messages won't be queued for another delivery attempt. As I understand it from talking to their support, if the server pings or sends any response at all, then Mail Assure will not keep a copy. It will also weirdly mark messages during that outage as rejected, so it's not like Mail Assure doesn't know that the message never reached the user(s).

Quotes from Members

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

Pros

"This appliance has helped in that we now eliminate the thousands of scams, spam, and malware emails that are destined for our users."
"The most valuable feature of Barracuda Email Security Gateway is that it blocks almost 99 percent of threats from users' email inboxes."
"From a front-end security point of view, Barracuda Email Security Gateway instantly reduced our spam, which is the main benefit that we are getting together with our customers."
"The most valuable feature of the Barracuda Email Security Gateway is the cloud ATP functionality not available on the on-premise version. Most of the zero-day attacks can be mitigated with ATP. Additionally, the reporting functionality is good."
"One advantage is its immediate deployment capability. So the fast speed to deploy is a big plus point."
"Great at blocking spam."
"We find the email security to be valuable."
"The security protection is the best and it's GUI is user-friendly."
"The only benefit from Mail Assure is its white label feature and its per-user licensing plus the ability to package archiving and spam protection into a single interface."
 

Cons

"The scalability needs improvement, it's the only feature that is required."
"Some customers experience issues with integration."
"Barracuda Email Security Gateway can improve email detection. We have some emails that are bypassing the threat scanning and there are some impersonation emails passing through."
"There is room for improvement in the management of multiple domains."
"The deep scanning feature needs to be improved."
"We had a case where right before a link was redirected and there was no chance to ignore it."
"Barracuda has shown difficulty in providing us with the solutions we sought."
"The solution should add automatic alerts to the mobile."
"This is a dud product with inferior spam filtering versus alternatives like SpamHero, and the continuity feature is essentially marketing fluff."
 

Pricing and Cost Advice

"The licensing cost is competitive, it's not too high and not too low."
"It is an expensive solution and I would rate it 5 out of 10."
"The licensing fees are part of a bundled support package that we pay for."
"We find the solution's pricing okay."
"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."
"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."
"Our licensing fees are approximately $4,000 per year, and this includes updates for the antivirus and spam signatures."
