Executive SummaryUpdated on Nov 5, 2024

Barracuda Email Security Gateway and Kiteworks are both leading solutions in their respective fields of email security and secure file transfer. Barracuda holds an advantage in email security due to its effective email threat management, while Kiteworks excels in secure large-scale file transfers and privacy controls.

Features: Barracuda offers anomaly-based spam detection, robust integration with LDAP and Active Directory, and email spooling capabilities during server downtimes. In contrast, Kiteworks provides extensive API capabilities, the ability to manage large file transfers with detailed tracking, and a secure content sharing experience emphasizing privacy controls.

Room for Improvement: Barracuda could expand its backup and recovery processes, address denial-of-service issues, and improve automated updates and API integration. Kiteworks can benefit from enhanced support speed, stabilized performance, and improvements to its admin console for more efficient user management.

Ease of Deployment and Customer Service: Barracuda offers on-premises and hybrid deployment options, although its customer support varies, particularly lacking in localized assistance. Kiteworks, with similar deployment forms, is lauded for comprehensive support despite experiencing some stability challenges. Both products are noted for having effective support teams.

Pricing and ROI: Barracuda presents a broad pricing range, offering competitive value, though concerns exist over pricing discrepancies in certain regions. Users criticize the rising renewal costs.

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 protection from Barracuda Email Security Gateway is essentially a sandboxing solution."

"It seems good in terms of spam blocking and virus blocking; it is lightweight, and we can filter all of our inbound and outbound emails, with controls for rate control, quarantine, and tagging, and we can see whether an email is a spam email or a phishing email."

"It can effectively combat phishing attacks, block spam, provide confirmation, and ensure operational manageability with a strong focus on product stability."

"This product is powerful and quite simple to use."

"Barracuda has one of the best email security solutions for SMB and big enterprises."

"I would suggest implementing Barracuda Spam, because this solution has a multi-factor threat analysis engine, which other products don't have."

"The initial setup was very easy and user-friendly."

"There are plenty of features, such as sandboxing capabilities with zero threat protection. It has all the leading email security appliances compared to other solutions."

More Barracuda Email Security Gateway pros

"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 solution removes the limitations with file attachment size that is found with regular email."

"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."

"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."

"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 most useful feature of this solution is to share files with external parties and we can use this functionality to share files internally too."

More Kiteworks pros

Cons

"The pricing is a little bit high, and it is causing the company to rethink renewal. If they could lower the pricing, that would be ideal."

"Barracuda Email Security Gateway can improve reporting and anti-spam. The anti-spam engine is not working well. We are seeing a lot of problems where spam is going through the gateway. Additionally, access privilege should be given to the IT support, because they don't have a lot of privileges. We are forced to give our IT support administrative access in order to clear and deliver emails and this should not be happening."

"There are limited administration controls that should be improved."

"There is room for improvement in the speed of the interface, specifically the cloud interface, is a bit slow."

"Few customers require an on-premises fabric ATP box for attack detection and response."

"The pricing of this solution could be improved."

"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."

"We had an incident where we didn't want to receive any emails or spam from a certain site and email address. We selected the mail ID, and we send it to Barracuda for analysis to see if it's spam or something like that. As of now, we haven't gotten any update or notification as to what happened with it."

More Barracuda Email Security Gateway cons

"We mainly had stability issues with kiteworks, where we were pushing the limits of its capability."

"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."

"File location could be improved."

"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."

"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."

"Perhaps there could be a notification to users about their bandwidth or network packet loss."

Pricing and Cost Advice

"We pay between $8 and $10 USD per user per month."

"This is one of the major points for integrating this solution in any organization. Barracuda Email Security Gateway needs to make it a bit more tolerable for customers because it is increasing every year. They should create a plan for reducing the cost."

"The solution requires a license and we pay annually."

"Barracuda Email Security Gateway is a cost-effective solution."

"The price of this solution is very high, but it's working fine."

"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."

"Our licensing fees are approximately $4,000 per year, and this includes updates for the antivirus and spam signatures."

"e solution's pricing is exceedingly high, and it continues to increase."

More Barracuda Email Security Gateway pricing and cost advice

"The price of Kiteworks is reasonable."

"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."

"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 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."
