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.

Improves decision-making with clear verdict explanations and works well across multiple environments
I know that a lot of time has been invested in improving the efficacy of the platform, and it shows; it performs very well. Moving forward, I think our focus should be on how to achieve better integration with other systems. While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value. This would allow it to be integrated more closely with the workflows of various teams and could potentially increase its market appeal. From my perspective, the tool itself functions exceptionally well, which gives me confidence in the system. I want to see this functionality extend to other tools that I use, enabling faster automation and improved workflows for the team, particularly from a security operations standpoint. I have no critiques regarding the tool itself. They've done an outstanding job and are maintaining high quality throughout their development process. They have a great product, and it's essential that they continue to uphold that standard, even though it requires significant effort.

Quotes from Members

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

Pros

"Cloudflare Access is a stable solution."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"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."
"Enables me to work from two locations."
"Clover is the best product globally."
"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"Cloudflare DDoS mitigates DDoS attacks."
"It is a stable solution."
"The program has a nice interface and it is easy to use."
"The product offers good and easy integration capabilities with other products."
"It's very easy to use, and the onboarding process is straightforward."
"It is fast and quite effective in terms of preventing any security incidents."
"The most valuable features would be its ability to intercept phishing emails and emails laden with malware, viruses, false links, etc."
"The sanitization feature of Check Point Harmony Email and Collaboration is valuable."
"The product is reliable and sturdy."
"As a comprehensive solution, Check Point offers a very granular and best-in-class experience."
"Since I have been using Sublime Security personally, I have noticed specific improvements like fewer spam emails and improved detection, which saves me time."
"Overall, the auditability and the ability to evaluate the information in Sublime through various mechanisms made me very comfortable with setting these capabilities to auto-remediation."
"I like its ability to detect and block."
"This is why it provides absolute value; it adds a smarter layer that catches anything missed by Microsoft 365 or Google Workspace protection, as attackers can breach those systems easily using flexible detection logic that security teams can quickly customize."
 

Cons

"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."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Cloudflare DDoS has poor technical support."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The initial onboarding was causing us some confusion."
"Our subscription plan for the solution has a limitation of bot signatures."
"A phishing simulator would be helpful as a user training module."
"Sometimes they do not provide immediate assistance, and it can take time for them to respond."
"I have learned enough to make the product stable. However, the stability has some challenges."
"I would like Check Point to extend its coverage to include more cloud applications."
"Expanding third-party integration would be beneficial. When I integrate with Microsoft 365, support for other platforms like Slack or Dropbox is limited."
"I can tell you that their management system, SmartConsole, is quite heavy and very slow, and the performance is a little bit weak."
"If Check Point finds something to be described as a clean email, it should have the option to automatically release it to the user. At the moment, we don't have that option."
"Some undefined threats can bypass the security system when there is a networking failure in the organization."
"While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value."
"I would say there are very minimal changes needed regarding Sublime Security; for first-time users, it can be difficult knowing how to write the tool."
"The ability for users to look at their own quarantine box needs improvement. So at the moment, it doesn't give you the ability to see every email that has been quarantined. No end-user has the ability to see what's being quarantined. It's only people who have access to the back-end platform that can actually see what has been quarantined. The end user doesn't know if they have an email that has been quarantined, only if they're expecting something that didn't come through."
"To improve Sublime Security, I think the learning curve is the primary concern; it is powerful, but it is not plug and play."
 

Pricing and Cost Advice

"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."
"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."
"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 prices are slightly expensive."
"The solution is not that expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"Usually, we pay for the licensing part on a yearly basis and not on a monthly basis. If Check Point's team is providing a good amount of discount, then it is very easy for us to select it since its competitors are also giving the best prices or best discounts."
"Cost is the main concern that every customer takes into consideration, and Check Point always negotiates a price that is affordable."
"Due to its pricing, I would say that Check Point Harmony Email & Collaboration is more suitable for medium to enterprise organizations."
"The pricing is in the middle. Check Point's pricing is not the highest in the competitive market."
"There are absolutely no additional costs to the standard licensing fees. One of the wonderful pieces is that CloudGuard SaaS is all-inclusive in its licensing. There's no a-la-carte functionality. You're getting 100 percent of the product for the licensing that you're paying."
"Being able to keep the phishing campaigns out of my company has been ROI for me."
"The pricing and licensing are always negotiable."
"As we are a non-profit organization, we got the tool with a good offer. On a yearly basis, we pay 10,000 Euro for 500 users, which also includes the technical support part."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
