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.

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.

Pros

"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."
"Cloudflare, in my opinion, was easy to implement."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare DDoS mitigates DDoS attacks."
"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."
"Enables me to work from two locations."
"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 is better than its competitors for its security, deployment, and scalability."
"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."
"Sublime Security has positively impacted my organization by helping our team reduce manual email triage and respond to phishing and BEC threats faster."
"I like its ability to detect and block."
"Sublime Security has improved our email threat detection and response by helping us identify phishing and Business Email Compromise campaigns faster, investigate related emails, and automate remediation, which has reduced our manual effort and improved our response time."
"Since I have been using Sublime Security personally, I have noticed specific improvements like fewer spam emails and improved detection, which saves me time."
"Sublime Security has positively impacted our organization by allowing us to do much less manual phishing detection and email detection, and now we can automate a lot of that, freeing up a lot of our security team to do other work."
"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

"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"They don't have a person to provide support for customers using the solution under their free plan."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Our subscription plan for the solution has a limitation of bot signatures."
"The onboarding process can be improved a little bit."
"The initial onboarding was causing us some confusion."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Sublime Security could be improved by enabling more integration, better customization of alerts, and more detailed reporting."
"There have been occasions where we would have liked a faster response, but the overall experience has been positive."
"To improve Sublime Security, I think the learning curve is the primary concern; it is powerful, but it is not plug and play."
"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 believe the main areas for improvement for Sublime Security are ease of onboarding and learning, as the platform has many powerful capabilities, making it take some time for new analysts to become comfortable with all the features and detection logic."
"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."
"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."
 

Pricing and Cost Advice

"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 solution's pricing lacks transparency."
"The solution is not that expensive."
"The prices are slightly expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
