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.

Targeted email filtering has reduced spam and phishing and now saves significant investigation time
The best features of Fortinet FortiMail include its techniques and tactics, which are highly effective compared to other solutions such as Microsoft 365. Although Fortinet FortiMail may not be as advanced in some aspects, it is well recognized for its strong performance in handling spam and phishing. It performs thorough mail scanning and also offers a sandboxing feature that enhances protection. Fortinet FortiMail has had a positive impact on my organization by significantly reducing unwanted email activities such as spam and phishing. It provides accurate detection and generates results that often exceed what can be achieved through manual analysis. Since deploying Fortinet FortiMail, I have observed a reduction in investigation time by at least 20 to 30 percent.

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 Access is a stable solution."
"It is a stable solution."
"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."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Cloudflare Access is part of the Zero Trust philosophy."
"It will take the blow rather than our applications should an attack occur."
"Fortinet FortiMail is rated an eight for the protection and features it provides in the on-premises setup."
"FortiMail has a low cost and high support."
"With the Fortinet FortiMail solution, you have a lot of advantages because of the effectiveness of security."
"The spam filtering is great."
"The most valuable features are the endpoint defense features, it is very secure."
"It is a very reliable program and it works great."
"The anti-spam feature is very valuable."
"FortiMail is an awesome product mechanically."
"I like the product's ZAP feature."
"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."
"The scalability is pretty good; it does what it is supposed to do."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"The solution's stability is very, very good. I didn't face any problems in the last year."
"It is easy to configure, easy to use, easy to add exclusions, easy to track, and easy to add anything else if you want."
"We use the solution to receive emails. We do not use the calendar function as our clients are slow adaptors to the latest features."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
 

Cons

"Our customers no longer use Cloudflare because its service is subpar."
"Feedback could be enhanced."
"Lacks a VPN feature to provide a secure connection to the data center."
"Our subscription plan for the solution has a limitation of bot signatures."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"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."
"The response time for support must be reduced."
"They don't have a person to provide support for customers using the solution under their free plan."
"The solution is user-friendly to a degree but the dashboard needs improvement."
"What's missing in Fortinet FortiMail is some sandbox information for some of the emails. It's probably configuration-based, where it could be configured on some emails. For example, there was malware in some emails that weren't detected in some of the Fortinet FortiMail sessions, but it should have been configured from my company's end to better catch scam emails, but overall, the solution is okay. At the moment, my company is okay with the current Fortinet FortiMail offerings, but in the past, because of a lack of understanding, my team wasn't able to quickly implement the geographical IP blocking feature. It was time-consuming to implement that feature, but that wasn't a fault of Fortinet FortiMail. The issue was from my team's end, but just by emailing the support team, that issue was resolved, so right now, there isn't any additional feature I'd like added to Fortinet FortiMail."
"Maybe FortiMail's integration could be better."
"The solution is user-friendly to a degree but the dashboard needs improvement."
"It would be nice if we could manage the solution from the cloud so I could handle things off-site if necessary."
"The solution lacks to provide more visibility when there is a problem, and it needs to be tracked."
"Sometimes it takes a little bit too long to determine if an email is good or not. It does delay our email, which does not make users happy."
"I would like it if the solution could be more affordable."
"The solution must improve the user experience."
"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."
"Performance and speed should continue to be improved."
"It kind of has a heavy footprint in terms of an implementation footprint."
"The security features could be better and more secure in the next release."
"The product needs more granularity. Some features, like encryption, are not available."
"It would be helpful for customers if Plan 1 features were included with EOP."
"The licensing can be on the expensive side, especially in the cloud space."
 

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."
