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

"Content disarming and analysis are essential features in our email security setup"
"It has the best feature for processed mail analysis."
"The return on investment for us was achieved since we did not have similar incidents again in our environment."
"We did not put serious thought into solutions by other vendors because after looking at Fortinet, we found that it was quite simple, good, and full of features."
"With Office 365, I would recommend using this solution as there would be no problem and everything will be taken care of."
"FortiMail Cloud is very fast."
"It is a good solution and a good choice."
"The most valuable feature is the advanced threat protection."
"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 benefits that Kiteworks has provided to its customers in terms of data sovereignty."
"The solution removes the limitations with file attachment size that is found with regular email."
"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 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."
"The most valuable aspect of Kiteworks is undoubtedly the private content network. This feature is particularly beneficial for us. Furthermore, it serves as a centralized platform that enables us to track and manage our information exchange."
"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."
 

Cons

"There are no specific new features I would suggest at this moment."
"When it comes to security, this solution is not as efficient as other products."
"This ease of use and user-friendliness is something we believe could be improved in FortiMail."
"The throwback with Sophos is that it had a huge problem with spam."
"The product could be improved by extending reporting tools and adding options for notification."
"Its GUI needs improvement."
"Fortinet FortiMail Cloud doesn't have AI features, making it an outdated tool for me."
"The price is relatively expensive."
"We have experienced some issues with stability due to bugs."
"It could be more stable. In the next release, it would be better if it was more stable with improved performance."
"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."
"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"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."
"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."
"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

"I see how manageable and flexible the licenses are."
"When we're talking about pricing, other products have about the same price. That is normal."
"I rate the price of Fortinet FortiMail Cloud a five on a one to ten scale, where one is the low price, and ten is the high price. It is an averagely priced product."
"A license for our company using FortiMail and FortiCare (filtering and support) was $4000."
"The licensing is for three years. In the beginning, we did not pay monthly, it was paid once for three years."
"It should cost around $60,000. We bought it as a bundle, so everything comes together in the license. That is standard."
"The price of this solution could be more competitive."
"You only have to purchase one license for multiple participants."
"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."
"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."
"The license management is changing and confusing. If I could make one change to it, it would be better license management through the API."
"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."
