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

"The security protection is the best and it's GUI is user-friendly."
"Barracuda is good at keeping the garbage from reaching your inbox."
"Barracuda Email Security Gateway is very simple to use."
"It catches a lot of things and has the ability to add domains as well as add senders and update their things."
"The protection from Barracuda Email Security Gateway is essentially a sandboxing solution."
"The solution is scalable."
"The link protection and anti-phishing features are great."
"It is an excellent, intelligent solution that provides maximum security from email attacks."
"The most valuable feature is the ability to allow end-users to manage their own information and data with minimal administration. That's the best feature from my perspective."
"The benefits that Kiteworks has provided to its customers in terms of data sovereignty."
"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."
"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 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."
"The solution can be used remotely; it's easy to upload and share files."
"The solution removes the limitations with file attachment size that is found with regular email."
"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."
 

Cons

"There's a bit of configuration work that's needed with the DNS service provider, but other than that, everything else should be very smooth."
"Two improvements that are needed include an enhancement in the proxy feature, as well as the ability to more fully automate patches and updates."
"Some customers experience issues with integration."
"The pricing needs improvement."
"Barracuda should have a sandbox feature in the appliances."
"The downsides of the solution stem from the fact that it is an expensive product, and one may see too many false positives when using it, making them both areas where improvements are required."
"The technical support is not available globally 24/7 and this is the biggest problem with the product."
"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."
"File location could be improved."
"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."
"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."
"It could be more stable. In the next release, it would be better if it was more stable with improved performance."
"In my experience, their technical support can be a little slow."
"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."
"Perhaps there could be a notification to users about their bandwidth or network packet loss."
 

Pricing and Cost Advice

"Barracuda Email Security Gateway is a cost-effective solution."
"We find the solution's pricing okay."
"e solution's pricing is exceedingly high, and it continues to increase."
"We are using the trial version right now, and before purchasing the license, we need to solve some of the issues that we are facing. We need a proper solution for our email, and then we will look into pricing. We have a vendor for licensing."
"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."
"There is an annual license required for this solution."
"Compared to other products, this solution is quite affordable."
"The licensing fees are part of a bundled support package that we pay for."
"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."
"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."
"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 price of Kiteworks is reasonable."
