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.

Advanced email defenses have protected healthcare staff and simplified incident response
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 DDoS mitigates DDoS attacks."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"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 is simple to use."
"The blocking feature is very good."
"Enables me to work from two locations."
"Clover is the best product globally."
"Cloudflare is simple to use."
"On a day-to-day basis, Proofpoint Email Protection has saved me about 50% of my workload, which has been a real godsend."
"The power, flexibility, configurability, and Proofpoint Email Protection's professional services were some of the biggest selling points for me at the time and the things that I benefited from the most."
"Proofpoint Email Protection is a strong and reliable solution for defending against advanced email threats, especially phishing and targeted attacks."
"At this point in time, there's nothing that needs to be changed or improved in the tool."
"It has been comprehensive and easy to use for both users and administrators."
"Proofpoint Email Protection has definitely impacted my organization positively."
"Using Proofpoint Email Protection has successfully reduced the volume of emails that we need to review."
"It's very good at identifying threats."
"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."
"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."
"I like its ability to detect and block."
 

Cons

"Our customers no longer use Cloudflare because its service is subpar."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"Our customers no longer use Cloudflare because its service is subpar."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The onboarding process can be improved a little bit."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Cloudflare DDoS has poor technical support."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The only downside with Proofpoint Email Protection is the cost."
"The initial setup is complex."
"The incident reporting on offer needs to be improved. It's lacking right now. It should be on the platform somewhere."
"They do not have an on-demand scan for the internal viruses and internal users, and they don't have a scan for the exchange server against viruses and spam as Symantec does."
"The Secure Mail aspect should have an Outlook add-in, instead of an external dashboard that outside users have to access."
"Proofpoint should have better integration with complex environments that need more than one instance of Proofpoint, as there are issues with nested instances."
"Integration for reporting needs to be improved, it's too complex."
"Proofpoint Email Protection can be improved in that it is quite a large product, so learning how to be fully conversant in it can take some time within the team; this is probably the biggest challenge at the moment for us, getting everyone fully conversant to support the product."
"To improve Sublime Security, I think the learning curve is the primary concern; it is powerful, but it is not plug and play."
"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."
 

Pricing and Cost Advice

"The solution is not that expensive."
"The solution's pricing lacks transparency."
"The prices are slightly expensive."
"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 pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
