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.

Helps to detect and generate reports on phishing emails and saves from email compromises
We use the solution for marketing and brand protection.  I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature.  The product's…

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 Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare DDoS mitigates DDoS attacks."
"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."
"Cloudflare Access is a stable solution."
"Clover is the best product globally."
"If spam or some kind of malicious email gets past Mimecast and gets into our email environment, we can go into Agari and we can search for it."
"I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature."
"They are very flexible as far as feature requests go."
"It is really important for large companies to have the brand protection that is provided by Agari."
"Agari offers very good brand protection and they are the core founder of the DMARC standard."
"It comes with a lot of helpful tips for complicated areas."
"Agari gives us visibility of our domain security, helps us manage our SPF, DKIM and DMARC records, prevents spoofing of our domains for phishing and ensures that our marketing and other emails are received correctly and not rejected as spam."
"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."
"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."
 

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."
"For the topic of improvement, providing some training material is one of my suggestions."
"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."
"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."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"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 product's user interface is clunky. We have difficulty in finding what we need. I would also like to see automation in the onboarding processes."
"The protocol is quite complicated, which may not be something that could be improved, but it would be better if it was simplified."
"Some customers in the financial sector do not like the cloud solution because they don't want data to be transferred to a US-based cloud."
"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."
"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."
"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

"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 solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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 solution is not that expensive."
"The pricing depends on the number of users; per how many mailboxes you have, but they're pretty negotiable with that, too."
"The tool is not expensive and I would rate its pricing a four out of ten."
"The price of the licensing is based on the volume of email."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
