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

"Cloudflare, in my opinion, was easy to implement."
"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."
"The blocking feature 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."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"It is a stable solution."
"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."
"Enables me to work from two locations."
"The most valuable features of Proofpoint Email Protection are the performance from being on the cloud."
"The solution is a great product and the best existing option in 2022."
"The archive feature is valuable."
"I recommend all of my customers to migrate and start using Proofpoint as it is secure, minimizes risk, and eliminates phishing attacks."
"The spam filter for email is good."
"It's very good at identifying threats."
"Before deploying Proofpoint Email Protection, we were frequently attacked by phishing and DDoS, and after deploying it, attacks have been reduced by up to 80 percent and phishing has been completely eliminated, so it is working very efficiently."
"Compared to other products, Proofpoint's real-time threat intelligence makes it less noisy; they collect and share threat information effectively, which benefits all customers."
"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."
"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."
 

Cons

"The initial onboarding was causing us some confusion."
"For the topic of improvement, providing some training material is one of my suggestions."
"Operating and tuning the product is difficult."
"The response time for support must be reduced."
"Our customers no longer use Cloudflare because its service is subpar."
"The initial onboarding was causing us some confusion."
"Our customers no longer use Cloudflare because its service is subpar."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Proofpoint Email Protection does miss a lot of phishing attacks, and threat actors are using AI to create these phishing attacks."
"The management portal of Proofpoint Email Protection has an outdated UI that requires an update for better usability."
"Proofpoint Email Protection's interface is confusing and could be improved."
"Every client always finds it expensive, but I don't know how much they're paying for it."
"We have some use cases that haven't been dealt with yet, so that could be improved."
"Proofpoint Email Protection could improve by reducing the price."
"Proofpoint Email Protection has a new approach to email security with its API feature. Currently, it only works with Office 365. In the future, it would be beneficial if it also works with Gmail, as Check Point is currently the only brand that has API email security for Gmail. It would be beneficial if Proofpoint Email Protection could add this integration, they would be more competitive with other vendors."
"Proofpoint has a lot of false alarms. Even their mail flow rules are not the best thing."
"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."
"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."
 

Pricing and Cost Advice

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that expensive."
"The prices are slightly expensive."
"The solution's pricing lacks transparency."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"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."
"It is multiple times more expensive, which made it very much less attractive."
"Proofpoint is fairly expensive."
"Proofpoint Email Protection is a reasonably priced product, which means that it is neither too low nor too high in terms of price."
"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 price is reasonable."
"It is expensive."
"Customers pay around $90,000 yearly for a 1,000-user organization, with the subscription license being the main expense, apart from implementation fees."
"Annually, it costs us about $92,000. This is pretty much what it costs us. There is no additional cost."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
