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.

Pros

"I'm very satisfied with the environment and the dashboard."
"Cloudflare is simple to use."
"Enables me to work from two locations."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare Access is part of the Zero Trust philosophy."
"Clover is the best product globally."

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"The solution has a user-friendly interface. It is easy to deploy and handle. You can easily troubleshoot the issues of the solution."
"The solution can scale."
"I like the anti-spam and security features of Fortinet FortiMail, and that its features complement each other."
"Fortinet FortiMail's most valuable features are its performance and security."
"I am satisfied with both the scalability and the stability of this solution."
"It has a very high level of security through special licensing with solutions like FortiGuard, sandboxing solutions in the cloud, and URL rewriting solutions."
"Fortinet FortiMail positively impacts my organization by reducing mail activities such as spam and phishing, and I have noticed specific outcomes since deploying it, such as reducing my time by a minimum of 20 to 30 percent."
"This solution is good for small and medium enterprise companies."
"The product is good. To date, we have not faced any challenges."
"The reviewer gave Mimecast Email Security a rating of 10 out of 10."
"Email security is the most valuable feature of the solution."
"It offers an easy initial setup."
"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."
"Its administration console is very easy to use. The administration console is absolutely important because you interact with the platform through it."
"The solution is scalable."
"The solution is pretty straightforward to use and easy to set up."
 

Cons

"They don't have a person to provide support for customers using the solution under their free plan."
"Cloudflare DDoS has poor technical support."
"Feedback could be enhanced."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Our customers no longer use Cloudflare because its service is subpar."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."
"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."
"ortiMail has some latency issues and sometimes takes time to receive emails."
"They should add a lot of threat-intelligence feeds from different sources - not only from one source (FortiGuard)."
"The main area for improvement is the pricing."
"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."
"The logging information is sometimes not clear or easy to understand."
"An additional feature that could be added is a pop-up screen notifying you that an email has been blocked, without having to double click on it to take you there it could provide you with a summary explaining why it was on hold or why was it spam when you hover over it with your cursor."
"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's price is an area with shortcomings, making it an area where improvements are required."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"The feature that should be included is to remove the block on the encrypted files."
"The interface isn't the best. How everything works on the back end is confusing."
"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."
"The attachment scanning feature doesn't work properly."
"While it's quick and easy, the initial setup could be more user-friendly."
"The product's interface could be improved to be more user-friendly."
"I'd like to have better support from the product in the future."
 

Pricing and Cost Advice

"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 prices are slightly 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."
"The solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"Cloudflare Zero Trust Platform's pricing is good."
"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."
"Pricing is straight-forward and renewable without complicated pricing structures."
"There is a license required for this solution."
"The price is acceptable for the support license it includes."
"It is an expensive product."
"You need to pay additional fees for premium support."
"The solution is quite pricey compared to other competitors in the market."
"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."
"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."
"The price of Mimecast Mailbox Continuity is expensive."
"It's an expensive solution."
"The product has good pricing in terms of return on investment."
"It is a bit expensive."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"For what it is, the product is overpriced."
"The product price is moderate. I rate the pricing a five out of ten."
