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.

Works

This is a dud product with inferior spam filtering

This is a dud product with inferior spam filtering versus alternatives like SpamHero, and the continuity feature is essentially marketing fluff. Failed deliveries, for example, they don't count it as an issue so those messages won't be queued for another delivery attempt. As I understand it from talking to their support, if the server pings or sends any response at all, then Mail Assure will not keep a copy. It will also weirdly mark messages during that outage as rejected, so it's not like Mail Assure doesn't know that the message never reached the user(s).

Quotes from Members

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

Pros

"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."

"Cloudflare DDoS mitigates DDoS attacks."

"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."

"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."

"I'm very satisfied with the environment and the dashboard."

"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 has different options that can be used to differentiate DDoS attacks."

"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."

More Cloudflare One pros

"The security features provided by Microsoft are robust."

"You can use the product to create special accounts."

"The simplicity and the easy deployment ensure that anybody who has worked on Exchange can easily work on this."

"It has a really nice web-based administration console."

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

"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."

"The initial setup of Microsoft Exchange Online Protection was easy."

"We like the holding facility that is available for potentially suspicious URLs, which allows a real-time review to be performed before the email reaches a user's inbox."

More Microsoft Exchange Online Protection (EOP) pros

"The only benefit from Mail Assure is its white label feature and its per-user licensing plus the ability to package archiving and spam protection into a single interface."

Cons

"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."

"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."

"They don't have a person to provide support for customers using the solution under their free plan."

"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."

"Cloudflare DDoS has poor technical support."

"The response time for support must be reduced."

More Cloudflare One cons

"The solution must improve the user experience."

"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."

"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."

"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."

"The tool is not 100% stable."

"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 would be helpful for customers if Plan 1 features were included with EOP."

"Microsoft has some training portals, but more could be developed."

More Microsoft Exchange Online Protection (EOP) cons

"This is a dud product with inferior spam filtering versus alternatives like SpamHero, and the continuity feature is essentially marketing fluff."

Pricing and Cost Advice

"The prices are slightly expensive."

"Cloudflare Zero Trust Platform's pricing is good."

"The solution is not that expensive."

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."

"The solution's pricing lacks transparency."

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

"Apart from the license fee for the solution, there are no additional costs."

"The solution should reduce the cost."

"The product is expensive."

"The pricing of the solution is reasonable."

"It's a high price."

"The product is bundled with Microsoft 365."

"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 solution is expensive but is backed by Microsoft's reputation."
