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

"I'm quite satisfied with the graphical user interface for Barracuda products."

"The beauty of Barracuda Email Protection is that it is easy to manage and simple to deploy."

"I don't see any other email security solution that stacks up against them."

"Barracuda Email Protection has positively impacted my client's organization by reducing almost 50 to 60 percent of phishing emails, making it more secure and allowing us to feel safe from phishing incidents."

"We now have a secondary backup of Office 365 that's much easier to retrieve compared to Microsoft. If someone deletes something in Office 365, we can get it back within Office 365, but it's difficult. Barracuda is much easier. There is a lot less management needed using Barracuda. The management becomes much easier for Office 365 and it's no longer on-prem, so there are fewer hours managing on-prem devices, servers, and things of that nature. We don't have network appliances anymore for the backup of our information."

"The best feature of Barracuda Email Protection is that it provides protection for Microsoft 365."

"When we got the service, it included the email archiver with unlimited storage."

"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."

More Barracuda Email Protection pros

"The solution is stable."

"On ease of use, it rates very high."

"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."

"The advanced threat analytics and URL filtering in threat detection are good features that are working well."

"It has an efficient email filtering feature."

"The product offers protection, email security, anti-spam, and antivirus."

"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."

"It's very easy to deploy and configure."

Cons

"They could simplify the licensing and the pricing."

"The platform's pricing needs improvement."

"I would like to see better integration with other products."

"Regarding the threat protection feature in Barracuda Email Protection, it does not help to manage threats or sophisticated threats."

"The product must enable bulk user management."

"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 customer service and support could be improved if the support were available directly in Europe. Currently, the support is often managed from India, so we sometimes need to wait due to the time zone difference. It would be quicker and better if the support were provided by European staff."

"The policies are set up in Barracuda by default; we don't have any control over them."

More Barracuda Email Protection cons

"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."

"I wouldn't recommend Cisco to others because I think Fortinet is better."

"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."

"The pricing could always be better."

"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."

"The physical appliance has been discontinued, although the platform still exists."

"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."

"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."

Pricing and Cost Advice

"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 solution's pricing is moderate, where it is neither cheap nor expensive."

"The price is similar to that of Microsoft 365."

"The product is expensive."

"We didn't have to pay a lot for the solution because we got it from a good vendor with a good user volume."

"Price-wise, this product is middle-of-the-road."

"Barracuda licensing model is good."

"The price of Barracuda Essentials is better than some of the competing products."

More Barracuda Email Protection pricing and cost advice

"The solution’s pricing is manageable."

"It is expensive compared to other vendors."

"The feedback from vendors and customer is that it is expensive."

"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."
