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

"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"The solution has different options that can be used to differentiate DDoS attacks."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare, in my opinion, was easy to implement."
"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."
"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."
"Fortinet FortiMail's most valuable features are antispam, antivirus, database, and data loss prevention (DLP)."
"Fortinet FortiMail is rated an eight for the protection and features it provides in the on-premises setup."
"Troubleshooting is very simple because you can see where the email was not delivered and why it would be considered as spam."
"I am satisfied with both the scalability and the stability of this solution."
"The most valuable features are the endpoint defense features, it is very secure."
"The integration with FortiSandbox is good, and something that we utilize often."
"They have a feature called CDR, Content Disarm, Reconstruction, click protection, and DLP for encryption purposes."
"The most valuable feature of the solution is the tool's ability to prevent phishing attacks."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"The product is good. To date, we have not faced any challenges."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"Mimecast certainly helped my customers reduce phishing emails."
"The Large File Send feature comes in handy when you have to send fairly large attachments."
"It does a good job for us, and its admin console is easy to use."
"The initial setup is very straightforward."
 

Cons

"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."
"The initial onboarding was causing us some confusion."
"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."
"The response time for support must be reduced."
"Our customers no longer use Cloudflare because its service is subpar."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"Cloudflare DDoS has poor technical support."
"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 product could incorporate even more artificial intelligence to enhance the functionality, but it is a competetive and intelligent product as it."
"I believe there is room for enhancement in content and web security features."
"The security products stop their operations once the subscription period expires. It is a wrong policy. If I trust a product, it has to continue working even after expiry. It should have a grace period of 30, 40, or 60 days. We can extend the subscription during those days. In some places, subscription extensions can take up to six weeks. During the renewal process, the support offered by the company is very poor. It also reduces security. We pay for the expired period but do not get protection during those times. The user of Fortinet FortiMail should have a feature to see spam names."
"In the Latin America market, some spam messages use Portuguese language. Some clearly spam messages would be better identified by the anti-spam if not for the language."
"I don't know if it is possible, but I would like to see Artificial Intelligence and machine learning introduced."
"The product should work on licensing and provide more detail once the license is selected for the customer."
"The product's cybersecurity features could be better."
"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."
"Mimecast Email Security is somewhat expensive compared to the competition in the Indian market, and the local presence is lacking as they do not have a local representative currently."
"As a user, the user interface of the management console could be upgraded, for example."
"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"As for areas for improvement within Mimecast Web Security, I believe there is quite a lot that can be improved."
"The solution is expensive in comparison to similar solutions."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"Technical support has been slower than it was in the past, likely due to the pandemic."
 

Pricing and Cost Advice

"The prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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 is not that expensive."
"The solution's pricing lacks transparency."
"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."
"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."
"Price-wise, you get what you pay for in Fortinet FortiMail. Apart from the licensing costs, no additional expenses are attached to the solution's pricing."
"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 tool is very expensive."
"It is reasonable."
"9,000 Euro per annum for Fortinet Mail and sandbox."
"Fortinet FortiMail is a little bit expensive."
"The licensing model for this solution is better because it is based on the box and not the number of users."
"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 price of Mimecast Mailbox Continuity is expensive."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The product has good pricing in terms of return on investment."
"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."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"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 licensing costs are per-user for the product that you get with them."
