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

"The solution has different options that can be used to differentiate DDoS attacks."
"It will take the blow rather than our applications should an attack occur."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"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."
"The blocking feature is very good."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"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."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"The solution has a user-friendly interface. It is easy to deploy and handle. You can easily troubleshoot the issues of the solution."
"Fortinet FortiMail's most valuable features are its performance and security."
"This solution is good for small and medium enterprise companies."
"The deployment is simple and once up and running it is easy to manage."
"The product's initial setup phase was very easy."
"Fortinet FortiMail's most valuable features are antispam, antivirus, database, and data loss prevention (DLP)."
"For me, Fortinet FortiMail is the best solution I have ever tried."
"The most valuable feature of Fortinet FortiMail is its fully detailed dashboard."
"The scalability is pretty good; it does what it is supposed to do."
"You can use the product to create special accounts."
"The initial setup of Microsoft Exchange Online Protection was easy."
"Microsoft Exchange Online Protection (EOP) is used essentially for email filtering, acting as an anti-spam and security product for email."
"The initial setup is just a standard process."
"It is easy to configure, easy to use, easy to add exclusions, easy to track, and easy to add anything else if you want."
"It is useful for local users and our company because we use Microsoft 365."
"The pre-set policies and configuration analyzer are the most valuable features."
 

Cons

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Our subscription plan for the solution has a limitation of bot signatures."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"The response time for support must be reduced."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Our customers no longer use Cloudflare because its service is subpar."
"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."
"The product could incorporate even more artificial intelligence to enhance the functionality, but it is a competetive and intelligent product as it."
"Sometimes, the tool flags legitimate incoming traffic as spam."
"I have little to say about possible improvements, but the configuration for content blocking could be better."
"Sometimes, authentic emails get blocked by the solution's firewall."
"Maybe FortiMail's integration could be better."
"There are features that other solutions have that this one is lacking, such as reporting options. I hope in future releases they advance their features list."
"It is not easy to install."
"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."
"The reporting needs a little bit of improvement."
"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."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"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."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"I would like to get reports about vulnerable connections from our clients with information about domains, public IPs, etc. That would be highly useful."
"The product needs more granularity. Some features, like encryption, are not available."
"The product's end-of-life cycle could be extended."
 

Pricing and Cost Advice

"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."
"Cloudflare Zero Trust Platform's pricing is good."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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 is on the higher side."
"I have no information on pricing for the competition because right now, my company is working only with Fortinet, but I can say that in general, the price for Fortinet FortiMail was accepted by the customers easily. The POC is also important when a customer is buying a solution. The customer wants to see how the product runs, and as Fortinet FortiMail is a stable product that runs without big issues, it has a bigger chance of getting chosen by customers over its competitors, even if its price may be a little higher. Pricing for the solution is competitive. Sometimes it's less, sometimes it's a little bit higher, but it isn't far from what other solutions charge."
"9,000 Euro per annum for Fortinet Mail and sandbox."
"Price-wise, the solution is not far from Microsoft ATP. So, it is affordable."
"The solution is reasonably priced compared to one of its competitors."
"Compared to its competitors, Fortinet's products are available at a higher price range."
"I find Fortinet FortiMail pricing reasonable. There's no additional cost apart from its standard licensing fees."
"You need to pay additional fees for premium support."
"The product is expensive."
"It's a high price."
"The pricing for the solution depends on what you are trying to achieve with the use of the product, but I know that it is not a cheaply priced product. Yearly payments have to be made towards the licensing fees of the solution."
"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."
"The price of Microsoft Exchange Online Protection is reasonable."
"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 should reduce the cost."
