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

"Cloudflare is simple to use."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"It is a stable solution."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"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 best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"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."
"I love the integration between Fortinet products."
"The GUI isn't hard to use. When we do a demo and explain the features of Fortinet products to our customers, they understand very quickly. They can easily manage their systems without us."
"The anti-spam functionality is good and works well."
"I would rate Fortinet FortiMail ten out of ten overall."
"The solution is very reliable and very stable."
"After implementing FortiMail, the spam, and malicious emails we receive have significantly reduced, making it much simpler to manage."
"FortiMail effectively filters all emails coming to our mail server, blocking malicious ones automatically."
"Technical support is great. They are able to look at their patches and offer quick responses. We even have an account manager in the Middle East. They are very good."
 

Cons

"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"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."
"The onboarding process can be improved a little bit."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The response time for support must be reduced."
"Our customers no longer use Cloudflare because its service is subpar."
"The initial onboarding was causing us some confusion."
"It is not easy to install."
"My customers frequently ask to have detailed documentation for FortiMail and FortiWeb as they have in FortiGate. What they currently have is not enough."
"Fortinet FortiMail's pricing could be improved."
"It's difficult for me to talk about areas for improvement in Fortinet FortiMail because I'm the general manager of the company and I'm an engineer with knowledge about the solution, but I'm not deeply involved in its implementation. As I mentioned previously, Fortinet FortiMail is also being used within the company, and I'm happy with its functionality, but sometimes, attacks pass and avoid the Fortinet FortiMail filters, but those could be very sophisticated attacks. There could still be an improvement in the filtering feature of the solution, though the security of Fortinet FortiMail is okay for me because I believe you can't implement one hundred percent security in any solution. The initial setup for the solution also needs improvement. The setup is supposed to be simple, but then the customer starts to complain that some of the false positive emails are reaching quarantine, so my team has to configure it again. There have been instances when Fortinet FortiMail rejects valid emails because some of the service partners of the customer have not been configured accurately, so the system considered valid mails as attacks to be quarantined, so aside from improving the filters, there should also be an improvement in the categorization of emails in the server. My team has to modify the configuration so that valid emails could pass and for Fortinet FortiMail to correctly filter the SPAM traffic. A feature that could be added to Fortinet FortiMail in its next release is advanced AI, so it can analyze and decide accurately on which mail is valid and which mail is SPAM."
"Header inspection and containerization, like on-prem premises sandboxing, need enhancement."
"Sometimes, authentic emails get blocked by the solution's firewall."
"Fortinet FortiMail could improve general user management. There are no password policies for users."
"I think they need to look into it and improve their signatures. This will help with blocking incoming spam emails."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The prices are slightly expensive."
"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."
"Fortinet FortiMail is a little bit expensive."
"Fortinet FortiMail is inexpensive."
"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."
"This is a good solution and value for the money."
"Fortinet Fortimail has reasonable pricing."
"If you don't need the full bundle that includes everything, you have options for the small or medium enterprise environments."
"Price-wise, the solution is not far from Microsoft ATP. So, it is affordable."
"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."
