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

"I would suggest implementing Barracuda Spam, because this solution has a multi-factor threat analysis engine, which other products don't have."
"The solution is largely stable, it can scale, and overall it has been working fine without issue, while the message tracking and messaging logs have proven to be quite useful."
"Its backups are valuable."
"The time it saves in eliminating inbox clutter and the focus that creates allows staff to be more productive instead of absolutely wasting time manually filtering spam."
"This solution has helped to significantly reduce the amount of junk email that we receive."
"We are using this product to protect us against spam and viruses."
"It is very simple to whitelist addresses."
"I appreciate that the product provides account takeover protection."
"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."
"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."
"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."
"Scalability is impressive."
"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."
"The solution can be used remotely, including from mobiles, and it's easy to upload and share files."
"As a file-sharing application, it's an absolute 10 out of 10."
 

Cons

"The technical support is not available globally 24/7 and this is the biggest problem with the product."
"This product can always be made more secure."
"We detect some failures in some mails; not all mails pass through consistently. Some mails pass while others are dropped without any apparent logic, despite having the policy set for specific recipients or senders."
"Solution requires regular checking to ensure it's 'keeping up' with spam."
"There is room for improvement in the speed of the interface, specifically the cloud interface, is a bit slow."
"Barracuda isn't catching everything. We're still getting quite a few phishing emails, so we're looking for something else."
"I have noticed that it takes a little time to get familiar with after deploying and some tweaks need to be done as things come up."
"It's not a scalable product. If we want to scale it then we have to change the device, because it is on-premises."
"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."
"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."
"It could be more stable. In the next release, it would be better if it was more stable with improved performance."
"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."
"We have experienced some issues with stability due to bugs."
"There is one particular thing that is a nuisance."
"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."
"In my experience, their technical support can be a little slow."
 

Pricing and Cost Advice

"I rate the price of Barracuda Email Security Gateway a ten on a scale of one to ten, where one is low price and ten is high price."
"The solution requires a license and we pay annually."
"e solution's pricing is exceedingly high, and it continues to increase."
"We paid for an annual license."
"It is a cost-effective and relatively cheap solution as compared to others. Our customers have a yearly subscription. We do have a few customers with monthly subscriptions, but they have cloud-based Email protection, which is a different type of solution. Both solutions are very good."
"Our licensing fees are approximately $4,000 per year, and this includes updates for the antivirus and spam signatures."
"The price of Barracuda Email Security Gateway is approximately $17 per user annually."
"Compared to other products, this solution is quite affordable."
"The license management is changing and confusing. If I could make one change to it, it would be better license management through the API."
"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."
"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."
"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."
"The price of Kiteworks is reasonable."
"The solution is very expensive because we are buying with Malaysian Ringgit and it's sold in US dollars."
