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.

Provides reliable real-time email protection and offers competitive pricing features
Regarding Kaspersky Security for Mail Server, I have not compared with other solutions, but I will compare and provide feedback. It is a reliable and fast security solution, and I can say it blocks better than other competitor software. Kaspersky Security for Mail Server has support for Windows and Linux, but regarding improvement, I have to dig deep and will have to do research on that. I have not checked into much detail about what can be better in Kaspersky Security for Mail Server. I have checked in general. If given some time, I can check and compare with other solutions. Regarding Kaspersky Security for Mail Server, I have found this is quite a good solution. It has a good response and good detection capability. I have not checked other products, so I cannot give any detailed or specific feedback regarding that. From what I have checked from Kaspersky mail security, it is satisfactory.

Quotes from Members

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

Pros

"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"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'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."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare DDoS mitigates DDoS attacks."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"Clover is the best product globally."
"Cloudflare is by far the most effective solution that I have come across."
"I would rate Fortinet FortiMail ten out of ten overall."
"I am satisfied with both the scalability and the stability of this solution."
"It is a scalable solution."
"This solution is good for small and medium enterprise companies."
"I highly recommend the product; the product is easy and there's no complexity, it's easy to use, easy to learn, easy to upgrade, easy to apply any changes, and it offers a good price versus quality balance."
"The most valuable feature of the solution is its interface, allowing users to get around the solution easily. The integration capabilities in the solution are also very easy."
"FortiMail has a low cost and high support."
"The product's initial setup phase was very easy."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"With both of them working together, we have the perfect solution for mail."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
 

Cons

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Cloudflare DDoS has poor technical support."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Our subscription plan for the solution has a limitation of bot signatures."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Feedback could be enhanced."
"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."
"Fortinet FortiMail can be improved in terms of its dashboard, which is small and not visually appealing, making deeper investigations difficult."
"I have faced issues from one of the customers that they received spam emails. I think they need to look into it and improve their signatures."
"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."
"I believe there is room for enhancement in content and web security features."
"The product's cybersecurity features could be better."
"The product's price is an area with shortcomings, making it an area where improvements are required."
"The product could incorporate even more artificial intelligence to enhance the functionality, but it is a competetive and intelligent product as it."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"The solution is not 100 percent stable and that can use improvement."
 

Pricing and Cost Advice

"The solution is not that expensive."
"The prices are slightly 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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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."
"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."
"It is an expensive product."
"Pricing is straight-forward and renewable without complicated pricing structures."
"There is a license required for this solution."
"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."
