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.

Provides robust email security features but requires improved modernization and complexity management

Modernization is an area that could be improved for Cisco Secure Email Threat Defense, as some features have lagged behind newer competitors, potentially offering more advanced analysis capabilities. The initial setup is not straightforward and requires expertise and time to master configurations such as spoofing and DLP. More control over backend functionalities and simplifying rule management could enhance user experience. 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. Furthermore, the pricing might deter new users who could opt for alternative, more cost-effective solutions.

Quotes from Members

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

Pros

"This is one of the easiest, safest, and most secure solutions for security and email archival."

"The most valuable features of Barracuda Essentials are it's a trusted name and is rated very high on review sites. It blocks high percentages of spam and junk email and it's in the cloud. They have hardware appliances, but this is in the cloud. The solution is very effective at blocking malware and blocking spam and this is what we are looking for. There's not a whole lot of complexity, you want a solution that is very good at blocking out all of the unwanted emails."

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

"The product is easy to deploy and maintain."

"The solution is straightforward to set up."

"The most helpful aspect for me is the out-of-the-box configuration, which is fairly good."

"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."

More Barracuda Email Protection pros

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

"The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."

"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."

"Cisco Secure Email Threat Defense's best features include user management of graymail, enhancing security awareness by allowing users to manage cold calls, sales-based items, and ensuring email compliance."

"Regarding stability, Cisco Secure Email Threat Defense is very stable."

"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."

"Cisco's technical support is very good."

"It has an efficient email filtering feature."

Cons

"The licensing and pricing need to be improved."

"They could simplify the licensing and the pricing."

"Regarding the price, I find it pretty expensive. It is not even reasonable; it is pretty expensive because we are dealing with the South African market and our currency is not as powerful as the dollar."

"Customers chose a different product after experiencing a problem when they upgraded the firmware, which caused the system to restart multiple times during working hours."

"There is room for improvement, particularly in reaching out to technical support during deployment."

"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."

"Barracuda Essentials can improve by continually adding more features."

"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."

More Barracuda Email Protection cons

"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."

"We encounter issues while searching for missing emails."

"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."

"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 solution is a bit expensive. It could be cheaper."

"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."

"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."

More Cisco Secure Email Threat Defense cons

Pricing and Cost Advice

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

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

"The product is expensive."

"Barracuda licensing model is good."

"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."

"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."

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

"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."

More Barracuda Email Protection pricing and cost advice

"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."
