Very good threat protection, spam filtering, and cloud backups

Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings. For instance, for email quarantine, I can't set up a global setting. Users must go through an induction session where I guide them in configuring quarantine alerts rather than having default settings based on group membership. This seems like an oversight since they already use Active Directory details. They should assign policies based on group membership, which configures these settings by default.

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

"I would rate the solution nine out of ten."

"The product is easy to deploy and maintain."

"The solution is straightforward to set up."

"The most valuable features of Barracuda Email Protection are flexibility and customization."

"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."

"The best feature of Barracuda Email Protection is that it provides protection for Microsoft 365."

"The most valuable features of Barracuda Essentials are it's a trusted name and is rated very high on review sites. It blocks high percentages of spam and junk email and it's in the cloud. They have hardware appliances, but this is in the cloud. The solution is very effective at blocking malware and blocking spam and this is what we are looking for. There's not a whole lot of complexity, you want a solution that is very good at blocking out all of the unwanted emails."

"The most valuable aspect includes attempts to spoof or compromise domains from external sources."

More Barracuda Email Protection 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."

"I can identify from which region our users are uploading or downloading files."

"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."

"The benefits that Kiteworks has provided to its customers in terms of data sovereignty."

"We could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."

"The solution can be used remotely; it's easy to upload and share files."

"Scalability is impressive."

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

More Kiteworks pros

Cons

"The platform's pricing needs improvement."

"Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings."

"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."

"The customer service and support could be improved if the support were available directly in Europe. Currently, the support is often managed from India, so we sometimes need to wait due to the time zone difference. It would be quicker and better if the support were provided by European staff."

"Barracuda Essentials can improve by continually adding more features."

"The solution's reporting mechanism is a little poor and could be improved."

"The product must enable bulk user management."

"Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings."

More Barracuda Email Protection cons

"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."

"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."

"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."

"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."

"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."

"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."

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

Pricing and Cost Advice

"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a seven out of ten."

"We pay annually. They never charged us for anything else. And they were quite a bit under that $20,000 mark. It was $19,074. And they've been pretty good about not skyrocketing the price or anything like that. It has gone up. It's gone up to $24,000 in 2020."

"The price is similar to that of Microsoft 365."

"The solution's pricing is moderate, where it is neither cheap nor expensive."

"Barracuda licensing model is good."

"The price of Barracuda Essentials is better than some of the competing products."

"We didn't have to pay a lot for the solution because we got it from a good vendor with a good user volume."

More Barracuda Email Protection pricing and cost advice

"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 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."

"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."

"The price of Kiteworks is reasonable."

"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."

Overview

The popularity of Microsoft 365 means criminals test and design their attacks to bypass its native security features. And that means you need additional layers of defense. With Advanced Threat Protection enabled, Barracuda uses multiple layers of detection, including signature, static, and behavioral analysis, along with CPU-emulation sandboxing to accurately detect and block zero-hour targeted attacks and ransomware.

Traditional email gateways use static rules and policies—reputation analysis, block lists, and malicious payloads—to determine if an email is malicious.

Barracuda protects your Microsoft 365 inbox against evasive threats with a powerful AI engine that learns the unique communication patterns within your organization through access to internal and historical emails. Once it understands what legitimate emails looks like for each user, it can detect anomalies that signal malicious intent. This context-based detection is more effective at blocking targeted attacks, which are designed to bypass traditional rule-based email security.

Barracuda Networks

Kiteworks empowers organizations to effectively manage risk in every send, share, receive, and save of sensitive content over numerous communications channels: email, file sharing, managed file transfer, APIs, and web forms. The Kiteworks platform unifies, tracks, controls, and secures sensitive content moving within, into, and out of an organization, significantly improving risk management and ensuring regulatory compliance.
