Cloud security has improved remote access and has reduced costs for smaller client sites
I have used Cloudflare One's Identity-Aware Proxy, and it is quite straightforward from what I have seen so far. The app registration on the Azure side integrates fully into Cloudflare, and I am very satisfied with that part because it is easy to set up. The integration of Cloudflare One's Secure Web Gateway and Zero Trust Network Access works without any issues. That part is pretty automatic, and if you complete the rest of the setup, it comes together by itself with no issues from my side. What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection. The hops get shorter and you get better latency. We have done testing to see if it is better. One thing that we did notice with our proof of concept with our current client is that they have people connecting from the UK. When they used their previous VPN solution, uploading CAD drawings and other files to the server took a long time. They mentioned that it is much quicker on Cloudflare One's solution. I definitely believe that is part of the improved performance, and I am satisfied with that as well. What is nice about Cloudflare One is that it makes the setup easier and also easier to train technicians to maintain it. Compared to legacy systems, we do not need to get fancy firewalls in place that are costly. That is definitely also a cost-saver with Cloudflare One.

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 blocking feature is very good."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"Cloudflare Access is part of the Zero Trust philosophy."
"It will take the blow rather than our applications should an attack occur."
"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare is by far the most effective solution that I have come across."
"The solution can be used remotely, including from mobiles, and it's easy to upload and share files."
"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 best part of this solution is that we can generate multiple reports about how the data is transferred and about user information or IP."
"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."
"We could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."
"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."
"It’s a great product that you should seriously consider and take the first step by training."
"The Tap and Trap features. They are the best features."
"My advice to others is the solution seems to be good and stable with a very easy-to-use user interface."
"Proofpoint Email Protection is a strong and reliable solution for defending against advanced email threats, especially phishing and targeted attacks."
"In the pros, we can see strong protection against phishing, spoofing, and malware threats, and good email filtering accuracy and threat visibility."
"A one-stop shop for email protection"
"As a cloud-based product, it can scale well."
"When I manage a SOC and Proofpoint Email Protection is integrated with it, it gives me a consolidated alert, so when phishing alerts come in it is slightly easier to manage, even my L1 incident response team from the SOC can easily understand the alerts, perform basic checks on VirusTotal, and create complete SOAR automation from that information."
"The most valuable feature of this solution is that it's a one-stop shop for email protection."
 

Cons

"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"For the topic of improvement, providing some training material is one of my suggestions."
"They don't have a person to provide support for customers using the solution under their free plan."
"The initial onboarding was causing us some confusion."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"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."
"We have experienced some issues with stability due to bugs."
"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."
"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."
"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."
"It could be more stable. In the next release, it would be better if it was more stable with improved performance."
"The solution should add post-sales training."
"Proofpoint Email Protection provides a solution for user training, which I did not end up going with because I chose KnowBe4. That is the only part I did not appreciate about it."
"Unfortunately, the whole product is going downhill right now, ever since they were sold to Thoma Bravo. We're constantly having problems with stability and the product in general."
"Proofpoint Email Protection could improve the Mail Trace feature and make navigation easier."
"The setup requires expertise. It needs someone with experience on managing it, and I would rate the implementation as needing someone experienced."
"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 only downside with Proofpoint Email Protection is the cost."
"The accessibility of Proofpoint Email Protection, particularly access to product trials, could be improved. It's hard to get a trial for Proofpoint Email Protection, and many customers prefer not just to do the POC or demo but try the product out."
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution is not that expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"The prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."
"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."
"The price of Kiteworks is reasonable."
"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."
"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."
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"The price is reasonable."
"Proofpoint Email Protection has comparable pricing."
"We sell annual licenses for this solution."
"The licensing is basically $8/user."
"The tool's pricing depends on the customer's preference, offering options for an annual license or a monthly subscription. The cost varies based on factors such as the number of users and specific requirements. Overall, the pricing is competitive."
"It is multiple times more expensive, which made it very much less attractive."
"In general, the pricing is competitive."
