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

"It’s a great product that you should seriously consider and take the first step by training."
"As a file-sharing application, it's an absolute 10 out of 10."
"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."
"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."
"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."
"The solution removes the limitations with file attachment size that is found with regular email."
"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."
"I can identify from which region our users are uploading or downloading files."
"It is a very scalable solution."
"The most valuable feature of this solution is that it's a one-stop shop for email protection."
"It has been comprehensive and easy to use for both users and administrators."
"Proofpoint Email Protection is quite scalable; I have not experienced any issues with the onboarding and offboarding of users and devices."
"The tool has improved our workflow by ensuring people receive only the emails they need for work rather than being inundated with hundreds or thousands of unnecessary emails daily."
"We have a lot fewer malicious emails coming in since implementing this product."
"My advice to others is the solution seems to be good and stable with a very easy-to-use user interface."
"Proofpoint Email Protection has positively impacted our organization in a very fruitful way."
 

Cons

"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"File location could be improved."
"It could be more stable. In the next release, it would be better if it was more stable with improved performance."
"We mainly had stability issues with kiteworks, where we were pushing the limits of its capability."
"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."
"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 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."
"For Proofpoint Email Protection, when it comes to support, there are times when they do not meet the SLAs for support, mostly on Fridays."
"Some of the old portal features of Proofpoint Email Protection are missing in the new portal, so some of the settings could be modernized."
"Proofpoint Email Protection could improve by allowing more customization of the reports, such as exceptions and black-and-white lists."
"They do not have an on-demand scan for the internal viruses and internal users, and they don't have a scan for the exchange server against viruses and spam as Symantec does."
"There are user interface complexities that require integration with a SOC team, which needs time and training."
"Proofpoint is a little bit expensive."
"Filtering false positives is highly challenging because it is impossible for humans to identify which emails are genuine and which are spam."
"I have not noticed much change in operational efficiency after implementing Proofpoint Email Protection, but the process execution is light."
 

Pricing and Cost Advice

"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 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."
"In general, the pricing is competitive."
"The price is reasonable."
"It is multiple times more expensive, which made it very much less attractive."
"Proofpoint Email Protection is a reasonably priced product, which means that it is neither too low nor too high in terms of price."
"Pricing has recently been increased and the cost is a downside"
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"Proofpoint Email Protection has comparable pricing."
"It is expensive."
