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.

Email security has protected financial data and provides clear tracking for every branch message
The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console. I don't think it was a database error or something, but we feel some slowness in configuring DLP and other content filters compared to other consoles. It may have been due to on-premises, but it was much noisy at some times while configuring DLP. When we tried to configure a DLP policy, the console became much slower. In that case, we cannot see what had happened in the mail which was blocked at that time. It may take nearly an hour to get back to normal while configuring policies. That is the major issue in the product.

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 capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare is by far the most effective solution that I have come across."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"The blocking feature 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."
"Cloudflare, in my opinion, was easy to implement."
"What I find the most valuable about Cisco Secure Email is that the logs are not that difficult to see even if you're not used to them. The logs are reasonably readable and diagnosing the problem is not too hard with them."
"It integrates with Active Directory and we can limit specific users to using specific applications."
"It provides good IT assistance."
"Cisco Secure Email has strong inbound services."
"The most valuable feature is the different content filters we are using, such as DKIM."
"It sends us reports, where we can see if there have been attacks, e.g. DDoS. If so, we can switch to a clean IP."
"Capital expenditure is a significant consideration, and the impact on major expenditures prompts a careful analysis before onboarding the new product."
"This is a great product with wonderful support."
"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."
"Since I have been using Sublime Security personally, I have noticed specific improvements like fewer spam emails and improved detection, which saves me time."
"I like its ability to detect and block."
"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

"Cloudflare DDoS has poor technical support."
"Our subscription plan for the solution has a limitation of bot signatures."
"They don't have a person to provide support for customers using the solution under their free plan."
"Our customers no longer use Cloudflare because its service is subpar."
"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."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"For the topic of improvement, providing some training material is one of my suggestions."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"It would be nice to have an easier way to check on the health of the system, how stressed these appliances are. Sure, you can do it, but it would be helpful to have an easier way to do it, maybe even at a glance."
"The management features of the product are not up to date."
"The user interface could be updated."
"The user interface needs massive improvement. While the device works fine and it's not complicated to write policies, renaming menu items and showing policy flow in conjunction with the application could help."
"We cannot manage multiple devices from a single UI."
"The primary areas for improvement are the pricing and the complexity of deployment."
"I would like to see features like AI since it is currently an area that the product lacks."
"Better dashboards and more interactive overviews would be nice, but the current functionality is sufficient."
"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."
"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that expensive."
"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."
"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"Cloudflare Zero Trust Platform's pricing is good."
"The prices are slightly expensive."
"The licensing was all transferred."
"There were no other costs in addition to the standard licensing fees."
"It is an expensive product. I rate its pricing an eight or nine."
"We were using Proofpoint and then we switched to Cisco... reportability was one of the main reasons we switched, but the biggest one was cost. If you can get an equivalent functionality for a better price it's wise to do so. That's what our primary decision came down to: We could get equivalent functionality at a lower price point."
"It is a relatively expensive option compared to other alternatives."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"Cisco Secure Email is expensive, but we get what we pay for."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
