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

"The solution has different options that can be used to differentiate DDoS attacks."
"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 is by far the most effective solution that I have come across."
"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 blocking feature is very good."
"Cloudflare Access is a stable solution."
"Cloudflare is simple to use."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"The sanitization feature of Check Point Harmony Email and Collaboration is valuable."
"Robust inspection technologies have proven valuable in safeguarding shared files in collaborative environments by analyzing patterns and identifying potential threats."
"The solution is stable and I think it does a fantastic job."
"The incorporated AI capabilities are particularly notable, functioning as AI versus AI, and it has protected us from various threats with a nice dashboard that shows if anything is missed by MS 365."
"The setup is very easy. I haven't faced any complexity with the setup of the solution."
"Check Point is a leader in the market."
"I recommend Check Point Harmony Email and Collaboration to all types of companies, from small businesses to enterprises."
"Data loss and data leakage prevention are well deployed which helps businesses to scale and expand effortlessly without any trouble."
"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."
"In terms of Sublime Security's impact, it has strengthened our email security posture, reduced the phishing risk, improved response time, and increased confidence in our security controls."
"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."
 

Cons

"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"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."
"Feedback could be enhanced."
"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."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The response time for support must be reduced."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"Our subscription plan for the solution has a limitation of bot signatures."
"The integration with Gsuite could be improved, especially when reporting the amount of emails it manages to filter."
"There are a few areas for improvement. One is the occasional sluggishness or latency, which is likely due to the cloud-based nature of the solution. So, the performance can be better."
"Some files are not scanned thoroughly due to occasional network failures."
"The only area for improvement is the language of the support. The support is only available in English."
"The next release should focus more on email categorization and provide options for unlocking blocked safe emails."
"We understand that false positives are always there, but sometimes the notifications are more than expected."
"Although it has good characteristics, it should improve the graphical interface and the latency that it sometimes presents."
"I would like the agents to perform better; sometimes, they are too heavy for endpoints, and they affect performance."
"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."
"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."
"Sublime Security is a great tool, but improvements are needed in areas such as better executive-level summaries, a more advanced reporting dashboard, and more automated remediation workflows."
 

Pricing and Cost Advice

"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."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution's pricing lacks transparency."
"The solution is not that expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Due to its pricing, I would say that Check Point Harmony Email & Collaboration is more suitable for medium to enterprise organizations."
"I rate the platform’s pricing a seven and a half."
"The pricing is competitive."
"The cost is similar to other competitors. It's not much higher."
"The price is very good, based on what they deliver."
"Cost is the main concern that every customer takes into consideration, and Check Point always negotiates a price that is affordable."
"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."
"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."
