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

"Cloudflare Access is part of the Zero Trust philosophy."
"Clover is the best product globally."
"The solution has different options that can be used to differentiate DDoS attacks."
"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."
"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."
"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."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"It is a stable solution."
"Cisco IronPort mail security was very helpful by blocking threats, viruses, worms and Trojans from attacking the mail accounts and user PCs."
"The solution works well."
"It saves a lot of time wasting, for example, phishing attacks distract a user's attention and forged emails waste a lot of time, and this solution helps protect user data."
"Compared with other mail security things, Cisco Secure Email was much better and easy to deploy also."
"IronPort really helped with the mail filtering and load balancing between the Exchange servers they had."
"There were detailed logs available. That was a seriously good feature... It turns out these were actually spoof emails that came into our environment. I got to know about them from the log system."
"Overall, the ease of migration to Cisco's cloud email security from the on-prem solution was a positive experience."
"The most valuable feature is the different content filters we are using, such as DKIM."
"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

"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Cloudflare DDoS has poor technical support."
"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 software has automated alerts, but the automated alerts are not available in the mobile app."
"Our subscription plan for the solution has a limitation of bot signatures."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Our customers no longer use Cloudflare because its service is subpar."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Many smaller businesses opt for more cost-effective solutions, such as Gmail or Hotmail accounts, instead of investing in Cisco Secure Email, given its higher cost."
"Cisco Secure Email can be improved from the administrator's point of view. Usually, you have to work with different areas, and they can try to make it easy for the administrator to use different functions."
"The configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations."
"Cisco is not good in dealing proactively or even reactively, so we end up relying on partners."
"They could improve the filters. In my time at the company, there were several times we had to contact support to update the filters."
"The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console."
"The primary areas for improvement are the pricing and the complexity of deployment."
"The Forged Email Detection feature needs improvement, particularly with domain. The sensors are not that good and the rules sets are unclear."
"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."
"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."
"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 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 prices are slightly expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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 solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"You're going to get what you pay for. If you're not willing to pay the price of Cisco, you're not going to get a product that's as good as Cisco. I don't think Cisco is overpriced, because for the last two years I've been comparing it to Microsoft and Cisco has been cheaper and given us more features."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"The price is significantly high."
"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."
"There were no other costs in addition to the standard licensing fees."
"It is a relatively expensive option compared to other alternatives."
"Cisco Secure Email and the support are priced well. It's not cheap, but there are other solutions that offer less and cost so much. For example, Microsoft is more expensive than Cisco."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
