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.

Email defenses have reduced phishing incidents and protect sensitive data across our enterprise
As things are evolving and threats develop in unpredictable ways, Proofpoint must adopt AI solutions and agentic solutions more aggressively and provide them to customers as part of service offerings. Inbuilt AI solutions would add more value and make Proofpoint a more premium choice for customers. With the help of AI solutions, agentic AI, and generative AI capabilities, the product would be more efficient than it currently is. Filtering false positives is highly challenging because it is impossible for humans to identify which emails are genuine and which are spam. Proofpoint should focus more on this area with back-end agents or other tools. Proofpoint should decide which emails are genuine and which are spam so it is not a challenge for end users. When receiving an email, end users should not have to determine whether to respond or not. Proofpoint should not release such spam emails and should strictly block such spam and spoof emails based on connection IPs. Currently, false positives occur in the product, and while this occurs in every product, it is an area where Proofpoint can focus on improving and reducing false positives. One email is enough for an end user to be deceived and lose money, so addressing this area is critical.

Quotes from Members

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

Pros

"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."
"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, including from mobiles, and it's easy to upload and share files."
"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 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."
"Scalability is impressive."
"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."
"It's detection of true positives are great, as it's cloud based it's very scalable and stable."
"It has been comprehensive and easy to use for both users and administrators."
"Proofpoint Email Protection positively impacts my organization because it is a simpler solution in terms of user interaction compared to my previous email gateway, and its detection capabilities are considerably more advanced."
"It is a very scalable solution."
"The solution's technical support is good. I rate the technical support a ten out of ten."
"Proofpoint Email Protection is very effective because they are very proactive, always ahead of the attackers, and were already detecting new kinds of attacks before customers thought about them."
"On a day-to-day basis, Proofpoint Email Protection has saved me about 50% of my workload, which has been a real godsend."
"It's a mature product. It does a good job in detection."
 

Cons

"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."
"There is one particular thing that is a nuisance."
"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."
"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."
"In my experience, their technical support can be a little slow."
"We mainly had stability issues with kiteworks, where we were pushing the limits of its capability."
"I think Proofpoint Email Protection could be improved if the user interface portals could be consolidated into a single portal, as there are currently four, five, or six separate ones."
"The reporting section could be enhanced. I like some reports but if they could allow us to create custom reports with more flexibility it would enhance the reports more."
"The solution could be improved with the addition of PLP and email encryption features."
"The Secure Mail aspect should have an Outlook add-in, instead of an external dashboard that outside users have to access."
"It became very expensive due to the nature of local circumstances, and I may advise Proofpoint to adjust marketing solutions based on each country."
"It has too many screens. It is kind of a conglomeration of products. In other words, they built product A, product B, and product C, and they are yet to integrate them into a single administrative console. I would certainly like to see a more seamless administrative interface. I would also like to see them include more bang for the buck, by including features like email fraud protection, rather than making their product so piecemeal, where you are buying little pieces. I agree with the idea of having multiple tiers or layers, but maybe as small, medium, and large, as opposed to an a la carte menu."
"The incident reporting on offer needs to be improved. It's lacking right now. It should be on the platform somewhere."
"The solution's server console and cluster dashboard have been the same for four years so need to be upgraded."
 

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."
"The price of Kiteworks is reasonable."
"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."
"Pricing has recently been increased and the cost is a downside"
"The solution uses a licensing model that is reasonable compared to other products."
"They are competitively priced, but I have been forced to get quotes for other solutions now because they haven't been responding to requests to do the work that we would like them to do."
"Proofpoint Email Protection has comparable pricing."
"Customers pay around $90,000 yearly for a 1,000-user organization, with the subscription license being the main expense, apart from implementation fees."
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"It is multiple times more expensive, which made it very much less attractive."
"The licensing is basically $8/user."
