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 is simple to use."
"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."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare, in my opinion, was easy to implement."
"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."
"It is a stable solution."
"Clover is the best product globally."
"The anti-spam feature is very valuable."
"Fortinet FortiMail is a very good product and reliable, and we find it easy to sell it."
"Troubleshooting is very simple because you can see where the email was not delivered and why it would be considered as spam."
"The most valuable feature of this solution is the spam filter."
"FortiMail is a stable product."
"We found the initial setup to be mostly straightforward."
"It is a very reliable program and it works great."
"Technical support is great. They're available 24/7 and their response time is typically within the hour."
"We can migrate seamlessly without any disruptions to our operations."
"The email policy configuration options in Microsoft EOP are satisfactory."
"It provides security to both on-premises and Azure infrastructures."
"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
"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."
"It is scalable."
"I like the product's ZAP feature."
"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."
 

Cons

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Operating and tuning the product is difficult."
"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Feedback could be enhanced."
"Cloudflare DDoS has poor technical support."
"The onboarding process can be improved a little bit."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Sometimes it takes a little bit too long to determine if an email is good or not. If they could shorten that time span, it'd be so much better. It does delay our email, which does not make users happy. That said, I would have to say we have not been blacklisted for quite a while now."
"The product's cybersecurity features could be better."
"In the future, I would like it if there's a possibility to lower the price of the bandwidth and UTM. It is quite expensive."
"The product could incorporate even more artificial intelligence to enhance the functionality, but it is a competetive and intelligent product as it."
"Limited ability to upgrade hardware may lead to some performance issues that might otherwise be improved."
"The solution could be improved by providing a virtual machine facility with a complete set of options in the VM setup and by enhancing the clarity of the information supplied for content filtering."
"I need a stable update in the product that stays for a long time instead of having to deal with frequent updates."
"The Ui isn't that intuitive."
"The product's end-of-life cycle could be extended."
"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."
"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."
"Performance and speed should continue to be improved."
"Microsoft has some training portals, but more could be developed."
"The management interface of Microsoft Exchange Online Protection (EOP) could be intuitive."
"They should specify the difference between Defender for Office 365 and Exchange Online Protection."
"The solution can be complex at times. It would be nice to have the on-server version. It needs to improve the stability as well."
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"Cloudflare Zero Trust Platform's pricing is good."
"The prices are slightly expensive."
"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 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."
"My company has a three-year license for Fortinet FortiMail, including the support, but I'm not so sure of how much the solution costs because I'm not part of the procurement team. What's more important to me is the functionality and stability of Fortinet FortiMail. In terms of Fortinet FortiMail licensing, the cost is calculated based on company requirements. For example, it's based on the features you need for your environment, on capacity, how many CPUs you have, etc."
"Pricing is straight-forward and renewable without complicated pricing structures."
"It is reasonable."
"It is a fairly priced product, considering what it does. The product offers good value for the money users spend on it."
"Price-wise, the solution is not far from Microsoft ATP. So, it is affordable."
"Pricing is based on initial license purchase and use volume."
"I find Fortinet FortiMail pricing reasonable. There's no additional cost apart from its standard licensing fees."
"Price-wise, you get what you pay for in Fortinet FortiMail. Apart from the licensing costs, no additional expenses are attached to the solution's pricing."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"The solution's pricing is subscription-based rather than a yearly licensing cost. Pricing is based on the size of the environment and company and can be expensive."
"On a scale of one to ten, where one is cheap, and ten is very expensive, I rate the pricing a six. For licensing, we can make monthly or yearly payments. Right now, we pay 5 USD per month to secure a person's license."
"The product is bundled with Microsoft 365."
"The pricing of the solution is reasonable."
"The tool's pricing is excellent."
"The price could be lower."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
