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.

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."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"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 is simple to use."
"Cloudflare, in my opinion, was easy to implement."
"It will take the blow rather than our applications should an attack occur."
"I'm very satisfied with the environment and the dashboard."
"The blocking feature is very good."
"From our experience with Fortinet FortiMail, we have found that it's a very strong platform for ensuring company security."
"FortiMail is extremely flexible and very easy to learn. Compared to other email security products that we've tried, it is mainly the ease of configuration that makes FortiMail valuable to us."
"FortiMail is a stable product."
"Fortinet FortiMail's most valuable features are antispam, antivirus, database, and data loss prevention (DLP)."
"The key benefits of this solution are its user-friendly interface and clear instructions, as well as the wealth of online resources and helpful health community available for support. These features make it easy for users to navigate and utilize the solution effectively."
"I would rate Fortinet FortiMail ten out of ten overall."
"After implementing FortiMail, the spam, and malicious emails we receive have significantly reduced, making it much simpler to manage."
"I love the integration between Fortinet products."
 

Cons

"The onboarding process can be improved a little bit."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"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."
"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."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Cloudflare DDoS has poor technical support."
"They should add a lot of threat-intelligence feeds from different sources - not only from one source (FortiGuard)."
"The solution could be improved by providing a virtual machine facility with a complete set of options in the VM setup."
"High Availability needs improvement."
"My customers frequently ask to have detailed documentation for FortiMail and FortiWeb as they have in FortiGate. What they currently have is not enough."
"The support could be faster because we've been receiving complaints from customers, they say that when they raise a ticket, it doesn't take 24 hours to respond, sometimes the support responds after three days. This is a lot of time."
"The product's cybersecurity features could be better."
"A room for improvement in Fortinet FortiMail is that it only has a hardware version. I also didn't find the solution scalable, so that's another area for improvement."
"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."
 

Pricing and Cost Advice

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that expensive."
"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 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 licensing model for this solution is better because it is based on the box and not the number of users."
"I find Fortinet FortiMail pricing reasonable. There's no additional cost apart from its standard licensing fees."
"Pricing is straight-forward and renewable without complicated pricing structures."
"In terms of licensing, we are using a virtual machine license for the single virtual server which it runs on. Doing it this way enables us to cut costs by only licensing FortiMail for our exact use case. If you need to expand in future, you can later buy extra licenses per virtual machine."
"The product's licensing part depends on the number of mailboxes and the hard disk needed by customers. The cost of the license depends on the number of mailboxes and the number of emails."
"It is a fairly priced product, considering what it does. The product offers good value for the money users spend on it."
"Fortinet FortiMail is inexpensive."
"Pricing is based on initial license purchase and use volume."
