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.

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 would rate the solution nine out of ten."
"I'm quite satisfied with the graphical user interface for Barracuda products."
"The product is easy to deploy and maintain."
"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."
"With Barracuda Email Protection, the features I find most valuable are spam filtering, as it is primarily used for spam protection."
"Barracuda Email Protection has positively impacted our organization because we rely on it to stop spear-phishing and phishing overall, enabling us to conduct our business securely."
"The archiving and search features are very good."
"The most valuable features are security and ease of use."
"The top two features are the two-factor authentication, which is pretty good. It's easily understood by the users. And their API is rather robust. We have numerous integrations that work off the API."
"I can identify from which region our users are uploading or downloading files."
"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."
"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."
"It’s a great product that you should seriously consider and take the first step by training."
"We could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."
"The solution removes the limitations with file attachment size that is found with regular email."
"The most valuable feature is the ability to send a large file of 30 GB in size and more. In Outlook and other email applications, you cannot send files that are larger than 20 MB. But with Kiteworks, 30 GB is transferable by default and, with the proper approval, a file of up to 100 GB can be sent. It makes file transfer very easy and smooth."
 

Cons

"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."
"My experience with pricing, setup cost, and licensing for Barracuda Email Protection is that it is a bit high."
"Barracuda Email Protection needs better reporting and more robust integration with security awareness training platforms and third-party solutions."
"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."
"They can still improve."
"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"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."
"File location could be improved."
"It could be more stable. In the next release, it would be better if it was more stable with improved performance."
"There is no offboarding process for end-users in Kiteworks. It's a manual process. There is no automated syncing with LDAP and checking to see if the account is still active. It's a manual process to get people out of here, which isn't the best way."
"In my experience, their technical support can be a little slow."
"Perhaps there could be a notification to users about their bandwidth or network packet loss."
"There is one particular thing that is a nuisance."
"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

"Barracuda licensing model is good."
"The product is expensive."
"The price is similar to that of Microsoft 365."
"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."
"The price of Barracuda Essentials is better than some of the competing products."
"Price-wise, this product is middle-of-the-road."
"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 solution's pricing is moderate, where it is neither cheap nor expensive."
"The solution is very expensive because we are buying with Malaysian Ringgit and it's sold in US dollars."
"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."
"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 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."
