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.

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.

Users report increased security awareness and effective training implementation

I am not familiar with the intelligent filtering system in PhishER Plus and whether it helps focus on actual threats. At the moment PhishER Plus meets our needs, but we could benefit from reports that show information from other companies. It would be useful to see what percentage of users from other companies make unsafe clicks. Currently, I cannot think of additional features that I would want to see in PhishER Plus. The current functionality seems sufficient for our needs.

Quotes from Members

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

Pros

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."

"Clover is the best product globally."

"Cloudflare is by far the most effective solution that I have come across."

"I'm very satisfied with the environment and the dashboard."

"It is a stable solution."

"The blocking feature is very good."

"Cloudflare DDoS mitigates DDoS attacks."

"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."

More Cloudflare One pros

"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."

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

"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 allow end-users to manage their own information and data with minimal administration. That's the best feature from my perspective."

"It’s a great product that you should seriously consider and take the first step by training."

"The benefits that Kiteworks has provided to its customers in terms of data sovereignty."

"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."

"The solution can be used remotely, including from mobiles, and it's easy to upload and share files."

More Kiteworks pros

"PhishER Plus is a user-friendly tool, we can get effective training with PhishER Plus which helps prevent clicks on real phishing emails and this experience saves company money."

Cons

"For the topic of improvement, providing some training material is one of my suggestions."

"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."

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."

"The response time for support must be reduced."

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."

"I would like them to include a VPN feature to provide a secure connection to the data center."

"Feedback could be enhanced."

"The software has automated alerts, but the automated alerts are not available in the mobile app."

More Cloudflare One cons

"There is one particular thing that is a nuisance."

"We have experienced some issues with stability due to bugs."

"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."

"Perhaps there could be a notification to users about their bandwidth or network packet loss."

"File location could be improved."

"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."

"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."

"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

"I am not familiar with the intelligent filtering system in PhishER Plus and whether it helps focus on actual threats."

Pricing and Cost Advice

"The solution is not that expensive."

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"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."

"Cloudflare Zero Trust Platform's pricing is good."

"The solution's pricing lacks transparency."

"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."

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"The prices are slightly expensive."

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

"The price of Kiteworks is reasonable."

"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 solution is very expensive because we are buying with Malaysian Ringgit and it's sold in US dollars."

"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 license management is changing and confusing. If I could make one change to it, it would be better license management through the API."
