Secures email by identifying threats and managing email policies effectively
The intuitive management interface feature makes email security policies very easy to implement as it's all about features that need to be enabled or disabled. Our investigation in any incident or mail is very useful as it provides all details about incoming mails, enabling thorough review and detection. The real-time threat intelligence feature is particularly useful as it detects all kinds of threats identified by incoming mails. The Impersonation license utilizes AI tools. Sometimes some phishing mails are reported as phishing, but they are not actually phishing mails. They are detected due to certain words and languages that appear suspicious but were generated by AI tools. Everyone or an advisor may use it for their own purpose or learning, even though it indicates that the mail detected is phishing when it's not.

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

"Barracuda Email Security Gateway has features like identify the spam source, rules to avoid some specific spams and then reschedule. And there are some other features like the email continuity, the email server and gateway site, which can relay the mail kit. The solution is user-friendly.These kind of features are the most valuable."
"The security protection is the best and it's GUI is user-friendly."
"Its backups are valuable."
"Their support is very good; you get German and from Austria, but they also have English support world-wide, with very good service and short response time."
"Barracuda Email Security Gateway is very simple to use."
"It not only tackles spam effectively but also incorporates advanced features like ATP and active features which ensures a comprehensive and adaptable email security solution tailored to their heterogeneous environment."
"The most valuable feature of Barracuda Email Security Gateway is that it blocks almost 99 percent of threats from users' email inboxes."
"The solution helps us to block some blacklisted emails."
"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."
"It’s a great product that you should seriously consider and take the first step by training."
"As a file-sharing application, it's an absolute 10 out of 10."
"Scalability is impressive."
"The solution can be used remotely, including from mobiles, and it's easy to upload and share files."
"We could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."
"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."
"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."
 

Cons

"Some of the phishing emails are not being blocked. Another problem is that we are not able to manage the date and time in our time zone."
"It's not a scalable product. If we want to scale it then we have to change the device, because it is on-premises."
"We had a case where right before a link was redirected and there was no chance to ignore it."
"Barracuda Email Security Gateway should include ATP in the next release."
"I had some difficulty in the past with the system getting swamped and overwhelmed trying to process all incoming traffic."
"The DMARC security is somewhat weak and could be strengthened."
"We would like to have a local support center in India so that they are operating in the same time zone and speak the same language."
"There are limited administration controls that should be improved."
"The system is extremely stable, but because it is a "COTS" system access is restricted and you must use the solution's support to make even simple changes, which increases the downtime."
"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."
"The one feature, which I have also requested directly to Kiteworks, is to have a scheduled upgrade function. Currently, one of my engineers logs in after hours for the upgrade. We're a hospital, and we're 24/7, but the primary users are seven to five. So, we log in the early evening just to push a button to tell it to do the update. It would be nice if that could be very easily scheduled."
"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"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."
"It could be more stable. In the next release, it would be better if it was more stable with improved performance."
"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."
"There is one particular thing that is a nuisance."
 

Pricing and Cost Advice

"Barracuda Email Security Gateway is an affordable solution that caters to small, midsize, and high-end businesses with great revenue."
"The licensing fees are part of a bundled support package that we pay for."
"We typically purchase a one or three-year license for Barracuda Email Security Gateway."
"The solution is priced low. We have received a good price discount here in Sri Lanka. There are additional licenses we have to purchase a license for the ATP."
"The regular pricing was initially very reasonable, but three years ago, Barracuda revised their price list and SKUs, resulting in a significant doubling of the standard prices."
"The price of the solution should be reduced. The price in the USA is less than where we are. Our local distributor of the solution is manipulating the market."
"As far as advanced email security systems, this product is mid-range on the pricing scale."
"Barracuda Email Security Gateway is a cost-effective solution."
"The license management is changing and confusing. If I could make one change to it, it would be better license management through the API."
"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."
"The solution is very expensive because we are buying with Malaysian Ringgit and it's sold in US dollars."
"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."
"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."
