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.

Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"This solution is easy to understand and easy to configure."
"Cloudflare Access is part of the Zero Trust philosophy."
"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."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"It is a stable solution."
"Cloudflare Access is a stable solution."
"The solution has a user-friendly interface. It is easy to deploy and handle. You can easily troubleshoot the issues of the solution."
"Through Fortinet FortiMail, we can perfectly authenticate each local mail service and mail release so that only authenticated mail goes out from our domain."
"This solution has protected us from email spam and from phishing."
"Fortinet utilizes specialized processing units, which network faster and sample more efficiently compared to others."
"Clean user interface and good sandbox."
"The product helps users handle security challenges as it offers prefiltering options and does relatively good incident reporting."
"Fortinet FortiMail has a lot of valuable features. It works great. It also has an antivirus feature. Support for Fortinet FortiMail was also great when my team wanted to block some geographic IPs, but couldn't figure out how to do it. The support team provided clear communication on how to resolve that issue. Another valuable feature of Fortinet FortiMail is SPAM filtering which tells you how many spammy emails you've received. Based on my current use cases, I'm happy with Fortinet FortiMail."
"The solution is very, very stable."
"In terms of technical superiority and the product itself, there are no complaints."
"It's good, it keeps the spam out."
"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."
"The solution is stable and reliable; there are no bugs or glitches, and it doesn't crash or freeze."
"We used Mimecast Mailbox Continuity when we had a power issue, and it works, has been pretty reliable, and the support has been quite good."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"If you want the ease of use, then Mimecast, or at least a cloud solution, is the way to go."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
 

Cons

"The response time for support must be reduced."
"For the topic of improvement, providing some training material is one of my suggestions."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"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."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Lacks a VPN feature to provide a secure connection to the data center."
"High Availability needs improvement."
"The solution's pricing is flexible and can be adjusted for African utility companies. Microsoft often offers special pricing formulas for African governments and organizations and it is similar to Fortinet FortiMail. In my country, government institutions receive discounted pricing from Fortinet FortiMail."
"The product should work on licensing and provide more detail once the license is selected for the customer."
"FortiMail's dashboard is somewhat complex and could be made simpler."
"It would be nice if we could manage the solution from the cloud so I could handle things off-site if necessary."
"The only drawback to this solution is that the firmware is frequently updated, and each update results in downtime."
"It is not easy to install."
"I think their statistics and the BI in general could be improved."
"Technical support has been slower than it was in the past, likely due to the pandemic."
"The filtering needs more flexibility."
"Lately, Mimecast's outbound mail servers have been regularly blocklisted by spam filters. That didn't happen a few years back, but it seems to be a more frequent problem these days. When a server is blocklisted, it means all of my outgoing mail ends up in the recipient's junk mail. That affects my reputation and business confidence."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult."
"External security features need improvement."
"As a user, the user interface of the management console could be upgraded, for example."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves."
"The installation is not so straightforward."
 

Pricing and Cost Advice

"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 prices are slightly expensive."
"The solution's pricing lacks transparency."
"The solution is not that expensive."
"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."
"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The price is acceptable for the support license it includes."
"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'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 an expensive product."
"The solution is reasonably priced compared to one of its competitors."
"FortiMail has extra charges for installation, configuration, and project management."
"The pricing is on the higher side."
"It's not as that expensive with the competitive different brands. The products sell a lot."
"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."
"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."
"The licensing costs are per-user for the product that you get with them."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
