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.

Targeted email filtering has reduced spam and phishing and now saves significant investigation time

The best features of Fortinet FortiMail include its techniques and tactics, which are highly effective compared to other solutions such as Microsoft 365. Although Fortinet FortiMail may not be as advanced in some aspects, it is well recognized for its strong performance in handling spam and phishing. It performs thorough mail scanning and also offers a sandboxing feature that enhances protection. Fortinet FortiMail has had a positive impact on my organization by significantly reducing unwanted email activities such as spam and phishing. It provides accurate detection and generates results that often exceed what can be achieved through manual analysis. Since deploying Fortinet FortiMail, I have observed a reduction in investigation time by at least 20 to 30 percent.

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.

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."

"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."

"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 mitigates DDoS attacks."

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

"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."

"It is a stable solution."

"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."

More Cloudflare One pros

"We found the initial setup to be mostly straightforward."

"The solution has a user-friendly interface. It is easy to deploy and handle. You can easily troubleshoot the issues of the solution."

"The user quarantine feature in the solution is good...It is a stable solution."

"Through Fortinet FortiMail, we can perfectly authenticate each local mail service and mail release so that only authenticated mail goes out from our domain."

"The anti-spam feature is very valuable."

"They have a feature called CDR, Content Disarm, Reconstruction, click protection, and DLP for encryption purposes."

"It is a very reliable program and it works great."

"We do have, as of late, spam outbreaks, and this solution has been pretty reliable in dealing with them."

More Fortinet FortiMail pros

"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 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 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."

"I can identify from which region our users are uploading or downloading files."

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

"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."

More Kiteworks pros

Cons

"Cloudflare DDoS has poor technical support."

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

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

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."

"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 response time for support must be reduced."

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

"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."

More Cloudflare One cons

"The solution doesn't scale easily."

"What's missing in Fortinet FortiMail is some sandbox information for some of the emails. It's probably configuration-based, where it could be configured on some emails. For example, there was malware in some emails that weren't detected in some of the Fortinet FortiMail sessions, but it should have been configured from my company's end to better catch scam emails, but overall, the solution is okay. At the moment, my company is okay with the current Fortinet FortiMail offerings, but in the past, because of a lack of understanding, my team wasn't able to quickly implement the geographical IP blocking feature. It was time-consuming to implement that feature, but that wasn't a fault of Fortinet FortiMail. The issue was from my team's end, but just by emailing the support team, that issue was resolved, so right now, there isn't any additional feature I'd like added to Fortinet FortiMail."

"I have little to say about possible improvements, but the configuration for content blocking could be better. So, for example, if the email includes the line "You have a Bitcoin", I would like it to be easier to block it before it enters an inbox. Fortinet could maybe offer better or simpler help on how to do this properly."

"The product could incorporate even more artificial intelligence to enhance the functionality, but it is a competetive and intelligent product as it."

"Limited ability to upgrade hardware may lead to some performance issues that might otherwise be improved."

"The main area for improvement is the pricing."

"The product should work on licensing and provide more detail once the license is selected for the customer."

"For example, there was malware in some emails that weren't detected in some of the Fortinet FortiMail sessions, but it should have been configured from my company's end to better catch scam emails, but overall, the solution is okay."

More Fortinet FortiMail cons

"In my experience, their technical support can be a little slow."

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

"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."

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

"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."

"We mainly had stability issues with kiteworks, where we were pushing the limits of its capability."

"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."

More Kiteworks cons

Pricing and Cost Advice

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

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

"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 solution's pricing lacks transparency."

"The solution is not that expensive."

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

"The prices are slightly expensive."

"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."

"You need to pay additional fees for premium support."

"I have no information on pricing for the competition because right now, my company is working only with Fortinet, but I can say that in general, the price for Fortinet FortiMail was accepted by the customers easily. The POC is also important when a customer is buying a solution. The customer wants to see how the product runs, and as Fortinet FortiMail is a stable product that runs without big issues, it has a bigger chance of getting chosen by customers over its competitors, even if its price may be a little higher. Pricing for the solution is competitive. Sometimes it's less, sometimes it's a little bit higher, but it isn't far from what other solutions charge."

"The fees for Fortinet FortiMail can be complicated. However, overall the pricing is fair."

"FortiMail is not cheap."

"There is a license required for this solution."

"The pricing is on the higher side."

"Compared to its competitors, Fortinet's products are available at a higher price range."

"I find Fortinet FortiMail pricing reasonable. There's no additional cost apart from its standard licensing fees."

More Fortinet FortiMail pricing and cost advice

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

"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."

"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."

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