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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Cloudflare, in my opinion, was easy to implement."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare is simple to use."
"Cloudflare Access is part of the Zero Trust philosophy."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"Enables me to work from two locations."
"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"The solution's stability is very, very good. I didn't face any problems in the last year."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"The initial setup is just a standard process."
"The security features provided by Microsoft are robust."
"It provides security to both on-premises and Azure infrastructures."
"The pre-set policies and configuration analyzer are the most valuable features."
"It's definitely scalable."
"With Microsoft Exchange Online Protection, if malware is attached to a mailer, it's very easy to go into the incident alert and find out what's happening with that identity and the mail."
"The solution provides protection with its Email Track Records and Machine Manual features."
"The technical support services are excellent."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
 

Cons

"Feedback could be enhanced."
"Cloudflare DDoS has poor technical support."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Operating and tuning the product is difficult."
"Our subscription plan for the solution has a limitation of bot signatures."
"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."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The management interface of Microsoft Exchange Online Protection (EOP) could be intuitive."
"Not all settings can be configured automatically and most still require manual configuration. However, there is an automation tool available that can be used to input all the configurations either as a script or a tool it would be helpful."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"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."
"They should specify the difference between Defender for Office 365 and Exchange Online Protection."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"The tool's classification for bulk email is cumbersome."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"The solution's pricing could be improved."
"The product's pricing could be more flexible."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"The solution is not that expensive."
"The solution's pricing lacks transparency."
"The prices are slightly expensive."
"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."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Online Protection is fairly expensive."
"It's a high price."
"The solution falls on the higher or more expensive side of the spectrum."
"The solution is priced high and could be less expensive compared to other solutions."
"Regarding the price, it's comparable to other service providers. We've also looked at Check Point's offerings, and the pricing doesn't seem to be an issue."
"The price of Microsoft Exchange Online Protection is reasonable."
"The pricing of the solution is reasonable."
"Apart from the license fee for the solution, there are no additional costs."
"Trend Micro is an expensive solution."
