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

"This solution has helped to significantly reduce the amount of junk email that we receive."
"The anti-spamming, anti-fishing features are great."
"Thanks to Barracuda Email Security Gateway, I have seen increases in productivity and functionality in terms of spam reduction and filtering against different threats, which is a benefit by default."
"It is lightweight, and we can filter all of our inbound and outbound emails. We have controls for rate control, quarantine, and tagging. We can see whether an email is a spam email or a phishing email."
"It is a really good product with a lot of features. It is responsive, updated, and modern. It is easy to use and has an easy interface for non-IT users. Its dashboard is also quite fine. It is also quite flexible and has an API at the backend."
"The interface of the Barracuda Email Security Gateway is pretty user-friendly, and you can easily navigate through it."
"I like Barracuda's cloud sandbox feature."
"It's easy to use. The configuration and web interface are user-friendly."
"The solution removes the limitations with file attachment size that is found with regular email."
"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."
"We could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."
"I can identify from which region our users are uploading or downloading files."
"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."
"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."
 

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."
"The solution should add automatic alerts to the mobile."
"The reporting can be improved."
"Barracuda Email Security Gateway can improve email detection. We have some emails that are bypassing the threat scanning. There are some impersonation emails passing through."
"The DMARC security is somewhat weak and could be strengthened."
"Barracuda isn't catching everything. We're still getting quite a few phishing emails, so we're looking for something else."
"Barracuda Email Security Gateway should include ATP in the next release."
"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."
"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 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."
"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."
"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"It could be more stable. In the next release, it would be better if it was more stable with improved performance."
"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."
"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."
 

Pricing and Cost Advice

"The licensing fees are part of a bundled support package that we pay for."
"The price of this solution is very high, but it's working fine."
"We typically purchase a one or three-year license for Barracuda Email Security Gateway."
"e solution's pricing is exceedingly high, and it continues to increase."
"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."
"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."
"Our licensing fees are approximately $4,000 per year, and this includes updates for the antivirus and spam signatures."
"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."
"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."
"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."
"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."
