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

"Enables me to work from two locations."

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

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

"Cloudflare DDoS mitigates DDoS attacks."

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

"It is a stable solution."

"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."

More Cloudflare One pros

"The spam filtering is great."

"The stability and performance of the solution have been great, and we have not had any problems since we have been using it."

"This excellent email gateway minimizes spam, inspects suspicious emails and isolates infected attachments with little administrative effort."

"The filtering is really effective to protect any mail environment of any company."

"The product helps users handle security challenges as it offers prefiltering options and does relatively good incident reporting."

"The solution can scale."

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

"This is a very stable product and all of our customers are happy that we use it."

More Fortinet FortiMail pros

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

"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 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 useful feature of this solution is to share files with external parties and we can use this functionality to share files internally too."

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

"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."

"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."

More Kiteworks pros

Cons

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

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

"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."

"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."

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

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

"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."

More Cloudflare One cons

"Fortinet FortiMail could improve general user management. There are no password policies for users."

"The dashboard is small, it doesn't have a huge dashboard that you can rely on, you need another application to work with it, which is why they created FortiAnalyzer."

"It's difficult for me to talk about areas for improvement in Fortinet FortiMail because I'm the general manager of the company and I'm an engineer with knowledge about the solution, but I'm not deeply involved in its implementation. As I mentioned previously, Fortinet FortiMail is also being used within the company, and I'm happy with its functionality, but sometimes, attacks pass and avoid the Fortinet FortiMail filters, but those could be very sophisticated attacks. There could still be an improvement in the filtering feature of the solution, though the security of Fortinet FortiMail is okay for me because I believe you can't implement one hundred percent security in any solution. The initial setup for the solution also needs improvement. The setup is supposed to be simple, but then the customer starts to complain that some of the false positive emails are reaching quarantine, so my team has to configure it again. There have been instances when Fortinet FortiMail rejects valid emails because some of the service partners of the customer have not been configured accurately, so the system considered valid mails as attacks to be quarantined, so aside from improving the filters, there should also be an improvement in the categorization of emails in the server. My team has to modify the configuration so that valid emails could pass and for Fortinet FortiMail to correctly filter the SPAM traffic. A feature that could be added to Fortinet FortiMail in its next release is advanced AI, so it can analyze and decide accurately on which mail is valid and which mail is SPAM."

"I'll rate it higher when it can be easier to configure or connect to the cloud to report on the attachments."

"I have little to say about possible improvements, but the configuration for content blocking could be better."

"The tool needs to improve its pricing policy. Also, it needs to be more user-friendly. I would want it to improve email security as well."

"A room for improvement in Fortinet FortiMail is that it only has a hardware version. I also didn't find the solution scalable, so that's another area for improvement."

"The UI could be better."

More Fortinet FortiMail cons

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

"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."

"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."

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

"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."

"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."

"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."

"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 prices are slightly expensive."

"The solution is not that expensive."

"The solution's pricing lacks transparency."

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

"Fortinet FortiMail has an annual license agreement."

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

"Fortinet Fortimail has reasonable pricing."

"If you don't need the full bundle that includes everything, you have options for the small or medium enterprise environments."

"This is a good solution and value for the money."

"The pricing is on the higher side."

"The tool is very expensive."

"The product's licensing part depends on the number of mailboxes and the hard disk needed by customers. The cost of the license depends on the number of mailboxes and the number of emails."

More Fortinet FortiMail pricing and cost advice

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

"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."

"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."
