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.

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.

Pros

"Cloudflare is simple to use."
"Cloudflare DDoS mitigates DDoS attacks."
"I'm very satisfied with the environment and the dashboard."
"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."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"It is a stable solution."
"Cloudflare, in my opinion, was easy to implement."
"It's definitely scalable."

"The email policy configuration options in Microsoft EOP are satisfactory."
"Microsoft Exchange Online Protection (EOP) is used essentially for email filtering, acting as an anti-spam and security product for email."
"It is scalable."
"The scalability is pretty good; it does what it is supposed to do."
"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."

Cons

"Feedback could be enhanced."
"The initial onboarding was causing us some confusion."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

"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 tool should provide on-premise versions. Currently, all versions are cloud-based."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"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."
"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 tool is not 100% stable."
"The security features could be better and more secure in the next release."
"Microsoft has some training portals, but more could be developed."
"I am somewhat happy with technical support from Microsoft. Sometimes it takes a while to get through to the right person or team."
"The tool's classification for bulk email is cumbersome."

"The product's pricing could be more flexible."
"The solution's pricing could be improved."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."

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