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.

"Cloudflare is by far the most effective solution that I have come across."

"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."

"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."

More Cloudflare One pros

"It's all running in the backend, so it doesn't affect the app functionality."

More Microsoft Exchange Online Protection (EOP) pros

Cons

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

"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 DDoS has poor technical support."

"Feedback could be enhanced."

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

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

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

More Cloudflare One cons

"Some features, like encryption, are not available."

"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 reporting needs a little bit of improvement."

"The security compliance features need to be improved. Sometimes, a client's mailbox becomes full because of retained information and not because of mail. I would like to see improvement in block rules as well."

"The tool is not 100% stable."

"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."

"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."
