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.

Helpful support, and useful dashboards

They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward. I haven't tried it in a while since then. Since I can't turn it off on a per-user basis, I had to turn it off globally. I have certain exceptions for not doing the sanitization, and how to set those up is not intuitive. It would be useful if there were a better way of doing that. Using digital certificates is hard. It would be better if it used Windows Servers' built-in certificate management.

Quotes from Members

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

Pros

"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."

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

"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."

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

"Kiteworks is easy to manage and maintain with a user-friendly interface and I recommend it to anyone that requires a file-sharing system that supports SFTP."

"The solution can be used remotely, including from mobiles, and it's easy to upload and share files."

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

"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."

More Kiteworks pros

"The most valuable feature of MetaDefender Email Security is the CDR. Customers purchase this solution specifically for data communication, as the other features can be obtained through other technologies that most customers already possess. Therefore, data communication serves as the foundation for the platform."

"The most valuable feature is called summary reconstruction which is used to deliver encrypted files to users."

"The sanitization is very good."

Cons

"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 system is extremely stable, but because it is a "COTS" system access is restricted and you must use the solution's support to make even simple changes, which increases the downtime."

"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."

"File location could be improved."

"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."

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

"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."

More Kiteworks cons

"The DLP should be upgraded and has room for improvement."

"They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward."

"Although the number of AV engines is good, it could be better."

Pricing and Cost Advice

"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 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."

"The solution is very expensive because we are buying with Malaysian Ringgit and it's sold in US dollars."

"According to our customers, the price of MetaDefender is high and it continues to increase by almost 15 percent each year."
