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.

There are many things that could be improved, but once you are very well-known about this application, you could perform that improvement plan. There are many scenarios where I have worked with Proofpoint Email Protection where a requirement was not fulfilled due to the limitation of the product. For example, we have Report Phish automation. With Proofpoint Email Protection, we can configure Report Phish and forward the email to any email addresses or shared mailboxes that we provide in the configuration. That email is forwarded as is with whatever the user reports as a phishing email. However, some organizations do not want the reported phishing email to go as is into their ticketing tool because it might contain malicious attachments and malicious links that are not required to go into their internal organization. Proofpoint Email Protection has that limitation. They cannot forward or restrict, but could forward only limited information such as some header information, sender subject details, or only limited information. As it is, the email can be forwarded, not as limited information. Proofpoint TRAP solution also has limitations. It cannot create alert notifications for some specific requirements because Proofpoint works the way it is designed, and if you want it to work based on our requirement, that should not be possible. There is a scope of limitations here. There are many improvements that should be made. First, they should work on their false positive minimization. Proofpoint generally takes all emails, investigates them, and classifies them. There are many situations where legit emails are blocked because that domain is found to be under a malicious category somehow, but actually it is not. False positive minimization could be improved, and they could enhance their other applications or solutions. There are many things that they could improve from each application and each portal.

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 best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"The blocking feature is very good."
"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 tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Enables me to work from two locations."
"The solution has different options that can be used to differentiate DDoS attacks."
"Clover is the best product globally."
"The solution offers very good flexibility. You can blacklist or whitelist with ease."
"The targeted attack protection that we use has been great, as has the email filtering and the rules that we have set for Proofpoint."
"A one-stop shop for email protection"
"The most valuable feature of this solution is that it's a one-stop shop for email protection."
"The most valuable feature is the ability to remove bad messages that were delivered, prior to being classified as unwanted."
"Considering Proofpoint Email Protection's end-to-end visibility in email threats, focusing on both the email and the person, it accomplishes what automation does in half the human work."
"Proofpoint Email Protection has positively impacted our organization's protection and has maintained security very well."
"The most valuable feature of Proofpoint Email Protection is the TAP Dashboard. It provides more detailed information that can be used for forensic analysis. This is an advantage that other email security providers, such as Cisco, IronPort, or Microsoft do not offer in their dashboards."
"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

"Feedback could be enhanced."
"Cloudflare DDoS has poor technical support."
"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."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The response time for support must be reduced."
"The initial onboarding was causing us some confusion."
"For the topic of improvement, providing some training material is one of my suggestions."
"I feel Proofpoint Email Protection can be improved by providing a better user experience."
"Proofpoint Email Protection can be improved by using more AI-powered features."
"The false positives are an issue."
"The largest complaint that we hear from our customers is that there is no local support."
"The initial setup is complex."
"It can be improved pricing-wise so that it is affordable for the SMB market."
"The support team was a bit slow."
"The stability and UI are the two areas of the solution with certain shortcomings that need improvement."
"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."
 

Pricing and Cost Advice

"The solution is not that expensive."
"The prices are slightly expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"Proofpoint Email Protection is a reasonably priced product, which means that it is neither too low nor too high in terms of price."
"Pricing has recently been increased and the cost is a downside"
"Proofpoint Email Protection has comparable pricing."
"The licensing is basically $8/user."
"Proofpoint is fairly expensive."
"The licensing model for Proofpoint Email Protection is simple. It's based on the number of users. Price-wise, Proofpoint Email Protection is a five out of ten because it's a pretty expensive solution."
"I rate the product price a seven on a scale of one to ten, where one is low price and ten is high price."
"The tool's pricing depends on the customer's preference, offering options for an annual license or a monthly subscription. The cost varies based on factors such as the number of users and specific requirements. Overall, the pricing is competitive."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
