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.

Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.

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

"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."
"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."
"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."
"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."
"Clover is the best product globally."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"It is a stable solution."
"It will take the blow rather than our applications should an attack occur."
"Overall, this tool's cost is fairly cheap given its features and excellent output."
"It is simple to deploy this platform and interact with the set features."
"Avanan Cloud Email Security has empowered teams with modern data security management knowledge and provided enough awareness that helps employees to prepare for any outcomes."
"It can retract unsafe emails and remove them from the entire communication channel."
"We are grateful for the solution and its great advances in connecting teams under a secure environment that cybercriminals cannot compromise."
"We have highly benefited from this platform since we deployed it, as it has provided reliable security to our email infrastructure and developed a secure working environment."
"In the overall experience, I have come to conclude that Avanan has the best email management tools that can prevent cyber attacks."
"It can detect corrupted files and filters out documents with viruses."
"The pre-set policies and configuration analyzer are the most valuable features."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"The threat management feature includes policies and alerts that are valuable."
"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."
"Overall, I think it's really a great product."
"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."
"Microsoft EOP's most valuable feature is a shared mailbox."
"The security features provided by Microsoft are robust."
 

Cons

"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 initial onboarding was causing us some confusion."
"Our subscription plan for the solution has a limitation of bot signatures."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"Feedback could be enhanced."
"The onboarding process can be improved a little bit."
"For the topic of improvement, providing some training material is one of my suggestions."
"Our customers no longer use Cloudflare because its service is subpar."
"The response to new threats is sometimes slow and can lead to data compromise."
"Sometimes it seemed like the allow list wasn't working. I've created many allow list rules however, they still seem to be blocked; the same is true with the blocked list rules."
"Integration with various SaaS offerings, who are leading in the SaaS market. Examples include: SNOW (ServiceNow), Salesforce.com"
"It should also offer a quick backup in case any email is wrongly quarantined or deleted to ensure no data loss."
"When sending bulky emails, the system slows down and takes a long time before it responds effectively to our requests."
"Familiarization with performance for new teams may take a long time."
"It is complicated for new users unfamiliar with the modern cloud networking infrastructure."
"The system could be designed to give corporate emails first priority due to demands."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
"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."
"It would be helpful for customers if Plan 1 features were included with EOP."
"The tool is not 100% stable."
"Online Protection has an issue in that it doesn't provide an option to stop impersonation."
"The product's end-of-life cycle could be extended."
"Performance and speed should continue to be improved."
"The security features could be better and more secure in the next release."
 

Pricing and Cost Advice

"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."
"Cloudflare Zero Trust Platform's pricing is good."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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 prices are slightly expensive."

"The product is not the cheapest in the market."
"Avanan’s price is comparable to Barracuda."
"Good pricing arrangement as an SaaS offering."
"Having the flexibility and modeling to do the pricing that best fits the needs of the organization is incredibly ideal. That is what Avanan does. They know exactly how many users are using it, etc. We can tune the invoicing associated with how we are using the product so we can charge it back to the shows appropriately."
"The pricing of Avanan is reasonable."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
"The solution should reduce the cost."
"The product is bundled with Microsoft 365."
"The price could be lower."
