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

"Fortinet FortiMail Cloud has had a positive effect on our organization since we can classify each email coming to our organization."

"One of the most beautiful benefits is its integration, as it can seamlessly integrate with any third-party email servers."

"Cost-wise, it's a bit expensive, but it's totally worth it."

"The most valuable features are the low price and its ability to integrate with other Fortinet products."

"If there is a problem somewhere Fortinet can act on it immediately. That is very important."

"Overall, it is a comprehensive and reliable solution."

"This is a solid email monitoring and security system that learns and maintains a two-way dialog with email system administrators."

"FortiMail Cloud is very fast."

More Fortinet FortiMail Cloud pros

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

"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."

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

"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."

"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."

"Scalability is impressive."

More Kiteworks pros

Cons

"Fortinet policies add an extra load to the endpoint."

"Fortinet FortiMail Cloud doesn't have AI features, making it an outdated tool for me."

"I would like to see more advanced sandbox features, where you can actually download to a machine where you can test."

"Networking should be simplified."

"Email sorting is missing from this solution."

"There are no specific new features I would suggest at this moment."

"The price is relatively expensive."

"The downside of this solution is that it is difficult to implement policies on FortiMail."

More Fortinet FortiMail Cloud cons

"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."

"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."

"In my experience, their technical support can be a little slow."

"It could be more stable. In the next release, it would be better if it was more stable with improved performance."

"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."

"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."

More Kiteworks cons

Pricing and Cost Advice

"You only have to purchase one license for multiple participants."

"It's on a subscribed basis."

"It should cost around $60,000. We bought it as a bundle, so everything comes together in the license. That is standard."

"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."

"The price of this solution could be more competitive."

"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"

"The product's price is reasonable."

More Fortinet FortiMail Cloud pricing and cost advice

"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."

"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."

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

"The price of Kiteworks is reasonable."
