Robust email protection with advanced features such as effective spam filtering, virus and malware defense, phishing protection and high scalability
Our customer faced a significant challenge with spam, leading to increased expenses. The complexity of their email infrastructure added to the issue, with some clients using Microsoft Exchange, others relying on different systems, and some operating on Linux platforms. To address this, we…

Two-factor authentication and .ZIP format make large file transfers very secure
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. Also, only the .ZIP format is supported because it is a very secure mode of file transfer, and that is why it is recommended. It also has built-in antivirus, so if it detects any malware it will quarantine the file and it won't be delivered. This is really important to keep the service up and running in a proper and secure manner. With people working from home, the data needs to be checked to see what kind of data is being sent. It has a two-factor authentication mechanism. For example, if a person with a particular domain is using Kiteworks and sends a file to a party outside of his domain, that external party has to go through two-factor authentication. The receiver gets a link that takes them to the setup of a temporary account, which will be valid for three days. The recipient will also receive a customized password separately. Only after all these steps will they be able to access the file. That access is only available to a person with the mail ID to which the file was sent. In addition, admins can see who is sending sensitive content, what that content is, and to whom it is being sent, and can track emails. One week of good training will give a user complete knowledge for using the solution. The system is very easy to use. You just click on "Compose," attach a file, and send it. It's very easy compared to Outlook or Teams. It's quite simple, even for someone logging in for the first time. It is very smooth and easy to send files.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The link protection and anti-phishing features are great."
"This solution has helped to significantly reduce the amount of junk email that we receive."
"All features it provides on the cloud environment are very, very useful, including the antivirus that is enabled on it."
"It is very simple to whitelist addresses."
"The spam filtering, in particular, is very important for us. We have a large volume of emails each month, something like 200,000, and Barracuda filters about 85 percent of the spam, malware, and phishing that comes in. It prevents our users from receiving this content on their computers."
"The anti-spamming, anti-fishing features are great."
"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 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."
"The benefits that Kiteworks has provided to its customers in terms of data sovereignty."
"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."
"The solution removes the limitations with file attachment size that is found with regular email."
"We could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."
"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."
"The solution can be used remotely; it's easy to upload and share files."
"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 allow end-users to manage their own information and data with minimal administration. That's the best feature from my perspective."
 

Cons

"Barracuda's spam database isn't on par with its competitors. Users complain about the spam email they're receiving, and we report the issue. Barracuda said they are going to update their system to block the malicious email we received, but we're still getting the same spam. The signatures are not in their database. They need to update their spam signatures because spam is bypassing Barracuda."
"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."
"Some customers experience issues with integration."
"False positives have given us issues."
"Artificial intelligence improvement could be used to help block spam and phishing mail that is directly delivered to users."
"The pricing needs improvement."
"The technical support is not available globally 24/7 and this is the biggest problem with the product."
"Barracuda has shown difficulty in providing us with the solutions we sought."
"File location could be improved."
"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."
"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."
"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."
"In my experience, their technical support can be a little slow."
"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."
 

Pricing and Cost Advice

"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."
"The pricing for the product is fine."
"Our licensing fees are approximately $4,000 per year, and this includes updates for the antivirus and spam signatures."
"We find the solution's pricing okay."
"Barracuda Email Security Gateway is a cost-effective solution."
"Barracuda has the best price. Every year we need to renew our license, and every year I need to compare Barracuda to two or three other players in the market. Barracuda always has a price that is 30 to 40 percent less than the other players' prices."
"We have a long agreement with Barracuda Email Security Gateway. We're very pleased with the cost and the solution. The cost is in the average range for this type of solution."
"Barracuda Email Security Gateway is an affordable solution that caters to small, midsize, and high-end businesses with great revenue."
"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."
"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."
"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."
