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.

Streamlined global file sharing with user-friendly interface and self-service capabilities

I'm not a network expert, however, there must be some room for improvement. Perhaps there could be a notification to users about their bandwidth or network packet loss. If users receive such notifications, they can understand any disruptions are due to issues with their network or bandwidth rather than the site or Kiteworks. Additionally, I work from offshore India, and I told my client manager to communicate with the Kiteworks forum salesman regarding one feature. I noticed the Kiteworks login UI is very basic, lacking customization. Allowing more HTML tags to add hyperlinks or user-friendly information on the home page would be very useful.

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."

"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."

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

"I would rate the solution nine out of ten."

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

"With Barracuda Email Protection, the features I find most valuable are spam filtering, as it is primarily used for spam protection."

"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."

More Barracuda Email Protection pros

"The best part of this solution is that we can generate multiple reports about how the data is transferred and about user information or IP."

"The benefits that Kiteworks has provided to its customers in terms of data sovereignty."

"It’s a great product that you should seriously consider and take the first step by training."

"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."

"Kiteworks is easy to manage and maintain with a user-friendly interface and I recommend it to anyone that requires a file-sharing system that supports SFTP."

"As a file-sharing application, it's an absolute 10 out of 10."

"The most valuable aspect of Kiteworks is undoubtedly the private content network. This feature is particularly beneficial for us. Furthermore, it serves as a centralized platform that enables us to track and manage our information exchange."

"We can see when people are sending things. We can definitely see who is sending to whom. From the administrative logs, we can see who is sending to an outside entity, and those logs are retained for quite a while."

More Kiteworks pros

Cons

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

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

"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."

"Sometimes, in some cases, this might end up with their teams being unfocused or a bit thin and stretched and super busy."

"The email encryption could be improved."

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

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

"Barracuda Email Protection can be improved by enhancing the reporting feature."

More Barracuda Email Protection cons

"We have experienced some issues with stability due to bugs."

"In my experience, their technical support can be a little slow."

"It would be nice if Kiteworks could provide a free version of the platform so that it could be used for a certain number of file transfers. We could be charged a fee if we exceeded the number of allotted file transfers."

"File location could be improved."

"Kiteworks could benefit from enhancing the proposal knowledge base section, specifically regarding the type of work involved. Currently, the knowledge base seems insufficiently dedicated to this topic, making it challenging for new users to access the relevant administrative law. Improving the visual aids and providing clearer explanations could alleviate this issue."

"I would like to see immediate releases of fixes because now it takes at least a week. If that time span can be reduced to one day or two days, that would be very helpful for users so that things are sorted and transactions work smoothly."

"We mainly had stability issues with kiteworks, where we were pushing the limits of its capability."

"There are always issues when there are bugs or upgrades. The challenge with upgrading is getting more storage from the customer. Every time we have a new version, it requires additional storage. This means that the customer would need to procure more storage for their server, which they don't like because it means additional cost to them. So, I think my request would be that the version upgrades don't require any significant storage requirement."

Pricing and Cost Advice

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

"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."

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

"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 product is expensive."

More Barracuda Email Protection pricing and cost advice

"I believe it's a little costly, but given the faith that we put into it from a security perspective to maintain the integrity of our patient information that is being transferred through this system, that's a small price to pay. So, on the surface, it might look like a lot of money, but depending on the need for security, which is where we feel it shines, it's okay price-wise."

"The solution is very expensive because we are buying with Malaysian Ringgit and it's sold in US dollars."

"The license management is changing and confusing. If I could make one change to it, it would be better license management through the API."

"The price of Kiteworks is reasonable."

"They changed it midstream. We were being charged a certain flat rate for SFTP traffic. For whatever reason, at the beginning of the year, our pricing changed, and we are now being charged more for using a feature of the product than we were when we first bought it. That has been our experience with billing. It turned out to be more expensive than when we started with it."

"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."
