Improved email security has reduced spam, simplified encrypted mail, and strengthened user trust
The best features Barracuda Email Protection offers include good spam filtering and very good sandboxing of all links, as well as good encryption. It also has integrated logging for user management of their own spam. It has better filtering technology, so few are false positives as well, with excellent anti-spam engines and logging. It is extremely easy to install, configure, and set up, and there is excellent message tracking for folks that say they have not received an email they were expecting. Integrated logging and user management make my daily work easier because it is very easy to log in and to manage this tool, hence making it a very good tool for email protection. It also has excellent, easy-to-add designated users as site administrators, and it is competitively priced. It has a user-friendly portal, strong cloud-based features, and no additional maintenance cost, along with responsive support. Barracuda Email Protection has positively impacted my organization by handling encryption better than any other tool I have used before, which has increased our email protection significantly. Our security has also increased from forty percent to sixty-five percent, especially when dealing with all the threats that come through emails. It has been a great tool because we can handle email delays and delays on file scanning. When our partners are happy, we are very happy, and it has helped us have less time chasing bad emails. The fast implementation of encrypted mail keeps employees working with less interruption since they are happy, satisfied, and secure.

Has faced challenges with configuration, taking actions, and learning curve but benefits from centralized management and good technical support
We have deployed Cisco Secure Email Threat Defense in two customer environments. It is still in development as a new product. Some customer requirements, such as sending logs to a Syslog server, are limited as ETD only supports sending audit logs. Customers have requirements for other system logs as well, which should be developed from their side. Another customer request is to restrict the IPs that can log in, which cannot be done from Cisco Secure Email Threat Defense yet. Any user with login details can log in. We can restrict the IPs in Cloud Mail Gateways, but not from Cisco Secure Email Threat Defense. It would be beneficial to improve this feature. Cisco Secure Email Threat Defense can take actions, such as requesting O365 to quarantine mail. In that case, the customer requires notification to the recipient from Cisco Secure Email Threat Defense. This option would be valuable if available. The real-time threat intelligence of Cisco Secure Email Threat Defense is an AI-based classification. It took one to two months to optimize the classification, but we still experience some false positives. Reducing the learning period would be beneficial. The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned. Reducing the learning time would be much better. Additional features desired in the next release include IP restrictions and user logging IP restrictions, ensuring only the customer environment can log in to Cisco Secure Email Threat Defense. Logs forwarding needs improvement as currently it only has audit logs. In Cloud Mail Gateway, we can create an IPsec tunnel to forward logs. However, in Cisco Secure Email Threat Defense, there is no option, and we must do API integration to send logs. Only SIM can get logs; Syslog cannot retrieve them.

Quotes from Members

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

Pros

"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."
"The main benefits Barracuda Email Protection provides for us are saving time and money because we don't run into any kind of attack or disruption in the mail service that we may face, including ransomware attacks."
"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."
"The most helpful aspect for me is the out-of-the-box configuration, which is fairly good."
"We found Barracuda to be more efficient, easy to use, and customizable."
"The investment in Barracuda Email Protection is quite good for us because we see the value of money on it, as we are saving a lot with Barracuda Email Protection, going from paying close to 300,000 to now sitting at 100,000."
"I would rate the solution nine out of ten."
"The solution's most valuable feature is impersonation detection."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"Cisco Cloud Mailbox is used for copying emails, anti-spamming, and securing the company's email, and we really enjoy the anti-spamming capabilities as well as the rejecting of bulk emails, which we can customize by adjusting the variables, and it is very user-friendly."
"It has an efficient email filtering feature."
"I highly recommend it as one of the best choices."
"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."
"The product offers protection, email security, anti-spam, and antivirus."
"This solution is easy to use."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
 

Cons

"Two to three months back, we got fraudulent emails in which someone in the organization was being blamed."
"Barracuda Email Protection needs better reporting and more robust integration with security awareness training platforms and third-party solutions."
"The solution's reporting mechanism is a little poor and could be improved."
"Barracuda Email Protection can be improved by enhancing the reporting feature."
"They could simplify the licensing and the pricing."
"The product must enable bulk user management."
"The technology works on a supervised engine, but it would be better if it ran on an unsupervised engine."
"Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings."
"The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"The solution is a bit expensive. It could be cheaper."
"The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"The physical appliance has been discontinued, although the platform still exists."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
 

Pricing and Cost Advice

"We didn't have to pay a lot for the solution because we got it from a good vendor with a good user volume."
"Barracuda licensing model is good."
"The solution's pricing is moderate, where it is neither cheap nor expensive."
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a seven out of ten."
"The price of Barracuda Essentials is better than some of the competing products."
"We pay annually. They never charged us for anything else. And they were quite a bit under that $20,000 mark. It was $19,074. And they've been pretty good about not skyrocketing the price or anything like that. It has gone up. It's gone up to $24,000 in 2020."
"The price is similar to that of Microsoft 365."
"The product is expensive."
"The feedback from vendors and customer is that it is expensive."
"The solution’s pricing is manageable."
"It is expensive compared to other vendors."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
