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

"This solution is easy to understand and easy to configure."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare Access is a stable solution."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"I'm very satisfied with the environment and the dashboard."
"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"The spam filtering is great."
"The product's initial setup phase was very easy."
"A full-featured email gateway solution that contains security threats reliably."
"It has a very high level of security through special licensing with solutions like FortiGuard, sandboxing solutions in the cloud, and URL rewriting solutions."
"For now, as per our experience with FortiMail in handling a large number of emails and spams as well, in the past three years, we have been protected and saved from any attacks from the outside."
"Fortinet FortiMail has been beneficial to my company; in the past, there were a lot of spam and phishing attempts, but after Fortinet FortiMail was implemented, it provided better protection against spam, phishing attempts, and ransomware."
"Fortinet FortiMail is very reliable and stable since the databases are very strong."
"I would rate Fortinet FortiMail ten out of ten overall."
"It provides security to both on-premises and Azure infrastructures."
"What I like most about Microsoft Exchange Online Protection is its integration with Windows, so we have one central view for all alerts and incidents."
"It offers great security against malware and other threats."
"It has a really nice web-based administration console."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"The email policy configuration options in Microsoft EOP are satisfactory."
"The product's most valuable feature is third-party integrations."
"The scalability is pretty good; it does what it is supposed to do."
 

Cons

"They don't have a person to provide support for customers using the solution under their free plan."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Our customers no longer use Cloudflare because its service is subpar."
"The response time for support must be reduced."
"The initial onboarding was causing us some confusion."
"Our subscription plan for the solution has a limitation of bot signatures."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Cloudflare DDoS has poor technical support."
"Fortinet FortiMail could improve general user management. There are no password policies for users."
"It can be easier to configure or connect to the cloud to report on the attachments."
"I believe there is room for enhancement in content and web security features."
"Limited ability to upgrade hardware may lead to some performance issues that might otherwise be improved."
"Fortinet FortiMail's technical support team has shortcomings and needs improvement."
"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 UI could be better."
"High Availability needs improvement."
"It doesn't protect against everything. We do need protection for, for example, endpoints."
"The product's end-of-life cycle could be extended."
"The reporting needs a little bit of improvement."
"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."
"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."
"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."
"The solution must improve the user experience."
"The solution lacks to elaborate on its spam policies."
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"The prices are slightly expensive."

"Cloudflare Zero Trust Platform's pricing is good."
"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 is not that expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"It is reasonable."
"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."
"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."
"9,000 Euro per annum for Fortinet Mail and sandbox."

"I find Fortinet FortiMail pricing reasonable. There's no additional cost apart from its standard licensing fees."
"The solution is priced high and could be less expensive compared to other solutions."

"It is a low-price solution."
"The tool's pricing is excellent."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
"The product is expensive."
