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.

Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.

Quotes from Members

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

Pros

"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"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 DDoS is better than its competitors for its security, deployment, and scalability."
"I'm very satisfied with the environment and the dashboard."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"It is a stable solution."
"Clover is the best product globally."
"The benefits that Kiteworks has provided to its customers in terms of data sovereignty."
"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."
"As a file-sharing application, it's an absolute 10 out of 10."
"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 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 solution removes the limitations with file attachment size that is found with regular email."
"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."
"Microsoft EOP's most valuable feature is a shared mailbox."
"It is an easy solution."
"The simplicity and the easy deployment ensure that anybody who has worked on Exchange can easily work on this."
"Overall, I think it's really a great product."
"I rate Microsoft Exchange Online Protection (EOP) nine out of ten."
"The most valuable feature of Microsoft Exchange Online Protection is the accidental release of information protection capabilities, and additionally, the solution is easy to use."
"It offers great security against malware and other threats."
"We like the holding facility that is available for potentially suspicious URLs, which allows a real-time review to be performed before the email reaches a user's inbox."
 

Cons

"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."
"The onboarding process can be improved a little bit."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"They don't have a person to provide support for customers using the solution under their free plan."
"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 tool should provide on-premise versions. Currently, all versions are cloud-based."
"Operating and tuning the product is difficult."
"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"We mainly had stability issues with kiteworks, where we were pushing the limits of its capability."
"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."
"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 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 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."
"The product needs more granularity. Some features, like encryption, are not available."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"It doesn't protect against everything. We do need protection for, for example, endpoints."
"If a company wants to put in line back-to-back anti-spam solutions, they need to work on that part because Microsoft recommends either you use EOP as a front line or you don't use it."
"Performance and speed should continue to be improved."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"When you're using a Microsoft product solution, you can scale it, but if you're not, there are limitations."
 

Pricing and Cost Advice

"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."
"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's pricing lacks transparency."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Cloudflare Zero Trust Platform's pricing is good."
"The prices are slightly expensive."
"The solution is not that expensive."
"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."
"The license management is changing and confusing. If I could make one change to it, it would be better license management through the API."
"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."
"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."
"On a scale of one to ten, where one is cheap, and ten is very expensive, I rate the pricing a six. For licensing, we can make monthly or yearly payments. Right now, we pay 5 USD per month to secure a person's license."
"Regarding the price, it's comparable to other service providers. We've also looked at Check Point's offerings, and the pricing doesn't seem to be an issue."
"The solution falls on the higher or more expensive side of the spectrum."
"The pricing for the solution depends on what you are trying to achieve with the use of the product, but I know that it is not a cheaply priced product. Yearly payments have to be made towards the licensing fees of the solution."
"The solution should reduce the cost."
"The solution is priced high and could be less expensive compared to other solutions."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
"The tool's pricing is excellent."
