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

"Cloudflare is simple to use."

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

"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."

"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."

"This solution is easy to understand and easy to configure."

"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."

"The blocking feature is very good."

More Cloudflare One pros

"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."

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

"Scalability is impressive."

"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."

"The solution can be used remotely; it's easy to upload and share files."

"The solution removes the limitations with file attachment size that is found with regular email."

"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 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."

More Kiteworks pros

"It is easy to configure, easy to use, easy to add exclusions, easy to track, and easy to add anything else if you want."

"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."

"The security features provided by Microsoft are robust."

"I like the product's ZAP feature."

"It provides security to both on-premises and Azure infrastructures."

"We use the solution in all our environments. We use it for remedy tickets and give them updates. It was our main communication point."

"The email policy configuration options in Microsoft EOP are satisfactory."

"Microsoft EOP's most valuable feature is a shared mailbox."

More Microsoft Exchange Online Protection (EOP) pros

Cons

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

"Our subscription plan for the solution has a limitation of bot signatures."

"Feedback could be enhanced."

"Cloudflare DDoS has poor technical support."

"They don't have a person to provide support for customers using the solution under their free plan."

"Our customers no longer use Cloudflare because its service is subpar."

"The response time for support must be reduced."

"The onboarding process can be improved a little bit."

More Cloudflare One cons

"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."

"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."

"File location could be improved."

"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."

"It could be more stable. In the next release, it would be better if it was more stable with improved performance."

"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."

"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."

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

More Kiteworks cons

"The reporting needs a little bit of improvement."

"The licensing can be on the expensive side, especially in the cloud space."

"The tool's classification for bulk email is cumbersome."

"The solution lacks to elaborate on its spam policies."

"The product could be more stable. Microsoft products could be more stable because sometimes, even though they are updating some things, we cannot find those updates."

"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."

"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."

"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."

Pricing and Cost Advice

"The solution is not that expensive."

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

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

"The solution's pricing lacks transparency."

"The prices are slightly expensive."

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

"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."

"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."

"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."

"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."

"The solution should reduce the cost."

"The pricing of the solution is reasonable."

"Online Protection is fairly expensive."

"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."

"The solution is expensive but is backed by Microsoft's reputation."

"The product is expensive."

"The solution's pricing is subscription-based rather than a yearly licensing cost. Pricing is based on the size of the environment and company and can be expensive."

"The product's pricing is competitive for the US market."
