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.

Email security has blocked sophisticated phishing and now protects inboxes with AI detection
The only challenge with Check Point Email Security (formerly Harmony Email & Collaboration) is that it is an API-based solution. In an API-based solution, the major challenge is that it can read email content and Google Drive content. This presents a data privacy challenge, and we had to mitigate it by signing a Data Processing Agreement and other agreements. Because it is not a traditional in-line solution, Check Point Email Security (formerly Harmony Email & Collaboration) connects with Google Workspace using API permission and can access email, attachments, sender, recipient information, links, and all metadata is with Check Point. Data storage and everything else is with Check Point, which is the challenge. This solution has a drawback because of API deployment, while other solutions are traditional secure email gateways that are in-line solutions. In those solutions, we need to change the MX record, but with this solution we do not need to change the MX record, which is a pro of API-based deployment. However, there is also a con in that with API solutions, the email is scanned but after delivery in the mailbox.

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

"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare, in my opinion, was easy to implement."
"Cloudflare Access is a stable solution."
"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."
"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."
"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."
"As with most of the other Check Point products, the CloudGuard SaaS has the advanced visibility of the events and alerts."
"The quarantine and release functionality for malware and junk mail is much more simplified than with previous products, and it has reduced effort in tickets and manpower not needing to do this for people who would have to normally put in a ticket."
"I can count the number of endpoints, emails, and collaborations being used in the environment."
"Check Point's technical support is very good."
"The most valuable feature of the solution is the phishing protection it offers."
"The solution is stable and I think it does a fantastic job."
"Over these eighteen months I have been working with the product, it has been very stable, and I would recommend it to most of my peers who have issues related to the email security piece."
"It protects cloud email and collaboration suites from cyber-attacks that evade default and advanced security tools. Its invisible, multi-layer security enables full-suite protection for cloud collaboration solutions such as Office 365, G-Suite, Teams, and Slack."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"With both of them working together, we have the perfect solution for mail."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"The most valuable feature is the straightforward setup."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
 

Cons

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."
"They don't have a person to provide support for customers using the solution under their free plan."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The onboarding process can be improved a little bit."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Support could be improved, as it is only available in English."
"Stability has been a pain point. I was going back and forth with my product engineer and project manager for a couple of months. I had the product in a demonstration mode and wasn't satisfied with the results initially. After a few alterations and a few revisions later, it is fine."
"I would like the agents to perform better; sometimes, they are too heavy for endpoints, and they affect performance."
"We have used technical support, but their response time is very slow. It needs to be improved."
"A signature-based filter could improve the solution's AI model for spam email."
"I would love to have their ticket resolution process as fast as possible."
"Check Point must develop one mobile app for iPhone users, Android phone users, and Windows phone users or at least for the administrator to see that dashboard on that particular app."
"The left-hand feature can be made more granular for the implementation of the policy."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"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."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
"The solution is not 100 percent stable and that can use improvement."
"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."
 

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 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."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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 prices are slightly expensive."
"The solution's pricing lacks transparency."
"Cost is the main concern that every customer takes into consideration, and Check Point always negotiates a price that is affordable."
"The pricing is in the middle. Check Point's pricing is not the highest in the competitive market."
"One of the nice features is that the licensing model is elastic, so if you go over your license count, you can add users during your billing cycle and true-up later."
"I rate the product's pricing a five on a scale of one to ten, where one is cheap, and ten is expensive."
"Check Point is more expensive. That's the honest truth. So far, it's a good value for the money."
"The pricing is competitive."
"The pricing and licensing are always negotiable."
"The product is expensive."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
