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.

"It has a very high level of security through special licensing with solutions like FortiGuard, sandboxing solutions in the cloud, and URL rewriting solutions."

"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
"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."

Cons

"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"The response time for support must be reduced."
"Our subscription plan for the solution has a limitation of bot signatures."
"Our customers no longer use Cloudflare because its service is subpar."
"Cloudflare DDoS has poor technical support."
"Sometimes, the tool flags legitimate incoming traffic as spam."
"The solution doesn't scale easily."
"The area that could use some improvement in Fortinet FortiMail is the integration process. I would like the integration to be easier."
"I'll rate it higher when it can be easier to configure or connect to the cloud to report on the attachments."
"The web console management interface could be improved."
"An additional feature that could be added is a pop-up screen notifying you that an email has been blocked, without having to double click on it to take you there it could provide you with a summary explaining why it was on hold or why was it spam when you hover over it with your cursor."
"The product could incorporate even more artificial intelligence to enhance the functionality, but it is a competetive and intelligent product as it."
"The infrastructure could be improved. The data leak prevention could also be better."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"The biggest issue that I experience is that Microsoft keeps moving things around, and it's very inconsistent as to where you find the information when you're trying to work on different pieces."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"When you're using a Microsoft product solution, you can scale it, but if you're not, there are limitations."
"Performance and speed should continue to be improved."
"Besides price, the main room for improvement includes the sandbox or something similar; the usability that solutions are focused on."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
"We would like the solution to have more in-built intelligence in the way that it reviews potential security risks, rather than our team constantly having to update the policies."

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.
