Senior Network Security Engineer at Vibs
Provides solid functionality and allows room for enhancing content management and support services
They can improve their CDR content profile and some anti-spam features. They don't have any direct script to run to add personalization, and we have to do it manually one by one. There are many tasks which we have to complete individually. We can't import files into the Fortinet FortiMail Cloud sensors. That's a drawback, as they need to provide a feature to import files. We can make the format, but we cannot import the file into Fortinet FortiMail Cloud. Additionally, in Fortinet FortiMail Cloud, not in FortiSandbox, they need to improve the block and allow list functionality to block URLs and allow specific types of URLs or regex.

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

"This solution is easy to install. The deployment takes about forty-five minutes."
"Fortinet and other software ensure that my company's email remains safe, helping to avoid access issues at some cost in production."
"From my experience, this tool is able to protect the network."
"Fortinet FortiMail Cloud has had a positive effect on our organization since we can classify each email coming to our organization."
"The scanners with FortiMail are valuable."
"FortiMail Cloud is very fast."
"Content disarming and analysis are essential features in our email security setup"
"The return on investment for us was achieved since we did not have similar incidents again in our environment."
"The solution removes the limitations with file attachment size that is found with regular email."
"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."
"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."
"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 benefits that Kiteworks has provided to its customers in terms of data sovereignty."
"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."
 

Cons

"This solution is slow and it should be made faster."
"Fortinet FortiMail Cloud doesn't have AI features, making it an outdated tool for me."
"This solution is expensive, so the pricing could be improved to be more competitive."
"The setup of the rules can be improved. I think it should be simplified and would be the best improvement in the system."
"There are no specific new features I would suggest at this moment."
"The price is relatively expensive."
"In endpoint security, they are not at the latest quadrant. That is why a customer with existing endpoint security solutions like Trend Micro might prefer a main security solution from that vendor."
"The throwback with Sophos is that it had a huge problem with spam."
"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 some issues with stability due to bugs."
"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."
"In my experience, their technical support can be a little slow."
"Perhaps there could be a notification to users about their bandwidth or network packet loss."
"We mainly had stability issues with kiteworks, where we were pushing the limits of its capability."
"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."
 

Pricing and Cost Advice

"You only have to purchase one license for multiple participants."
"The licensing is for three years. In the beginning, we did not pay monthly, it was paid once for three years."
"The pricing depends on various factors, including the type of licenses and subscriptions you have procured"
"I see how manageable and flexible the licenses are."
"The price of this solution could be more competitive."
"A license for our company using FortiMail and FortiCare (filtering and support) was $4000."
"When we're talking about pricing, other products have about the same price. That is normal."
"It's on a subscribed basis."
"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."
"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 price of Kiteworks is reasonable."
"It is not really expensive. I mean, to me it's obviously expensive, but it's worth 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."
