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.

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."
"The blocking feature is very good."
"Cloudflare Access is a stable solution."
"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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."
"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 deployment is simple and once up and running it is easy to manage."
"Both logging and reporting are very good, as well as the antivirus profiles, content emails, content profile, and application profile."
"Fortinet FortiMail is easy to use and the detection rate is very good. You can customize content filters and profiles are done easily. Additionally, there is a sandbox integration feature that is good."
"The integration with FortiSandbox is good, and something that we utilize often."
"FortiMail is a stable product."
"I love the integration between Fortinet products."
"The anti-spam functionality is good and works well."
"For now, as per our experience with FortiMail in handling a large number of emails and spams as well, in the past three years, we have been protected and saved from any attacks from the outside."
"The email policy configuration options in Microsoft EOP are satisfactory."
"What I like most about Microsoft Exchange Online Protection is its integration with Windows, so we have one central view for all alerts and incidents."
"Microsoft EOP's most valuable feature is a shared mailbox."
"Online Protection's most valuable feature is its admin interface."
"The initial setup is just a standard process."
"It is scalable."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"The pre-set policies and configuration analyzer are the most valuable features."
 

Cons

"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 One is not very powerful, but for what we require, it is basic and sufficient."
"Our customers no longer use Cloudflare because its service is subpar."
"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."
"Operating and tuning the product is difficult."
"For the topic of improvement, providing some training material is one of my suggestions."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The onboarding process can be improved a little bit."
"It is not easy to install."
"The IDE feature in Fortinet is not as good as the rest of the product because it's very difficult to deploy it."
"I think the security of the product could improve."
"I would like it if the solution could be more affordable."
"Issues with the current email search functionality."
"Header inspection and containerization, like on-prem premises sandboxing, need enhancement."
"The solution's pricing is flexible and can be adjusted for African utility companies. Microsoft often offers special pricing formulas for African governments and organizations and it is similar to Fortinet FortiMail. In my country, government institutions receive discounted pricing from Fortinet FortiMail."
"There are features that other solutions have that this one is lacking, such as reporting options. I hope in future releases they advance their features list."
"Performance and speed should continue to be improved."
"Our company faces difficulty with Microsoft Exchange Online Protection (EOP) because it's too big, clunky, and difficult for a small client to implement quickly and easily."
"It doesn't protect against everything. We do need protection for, for example, endpoints."
"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."
"The product needs more granularity. Some features, like encryption, are not available."
"The tool is not 100% stable."
"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."
"The tool's classification for bulk email is cumbersome."
 

Pricing and Cost Advice

"The prices are slightly expensive."
"The solution's pricing lacks transparency."

"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."
