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.

Consistent threat hunting and anomaly detection deliver valuable insights for network security management
In terms of improvement for Darktrace, pricing is the main concern. Pricing bothers me and this is one of the major factors when choosing a solution. When we get feedback from customers, that's the only felt need. When we factor in Darktrace, we do it only limited. We put it on where the perimeters and connections are, but still, some gray areas are left out, especially if we have multiple branches. We need Darktrace on each branch to get the data out, and I suggest having some kind of a centralized product that gets data from multiple sources to aggregate and provide the data.

Straightforward to set up, reliable, and offers good functionality
We primarily use the solution for email security and general email management.  It's improved our productivity.  The solution works well overall. The functionality is very good.  The setup process is easy.  It is stable and reliable. It's scalable.  I don't have any specific areas that need…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"Cloudflare DDoS mitigates DDoS attacks."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare, in my opinion, was easy to implement."
"I'm very satisfied with the environment and the dashboard."
"This solution is easy to understand and easy to configure."
"Enables me to work from two locations."
"The most valuable feature is that it works autonomously."
"The autonomous mode, which is the Antigena AI response, is particularly valuable."
"The most valuable feature is the solution's ability to trim out the false positives and point your attention to the real important stuff."
"I would 100% recommend Darktrace."
"t was pretty as far as the granularity of what you were getting out of it."
"The autonomous response is also highly designed in Darktrace."
"I find it very good in the way that they show the past events, including the attack history."
"Darktrace is valuable since it offers full packet capture and detailed metadata."
"It is stable and reliable."
 

Cons

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"They don't have a person to provide support for customers using the solution under their free plan."
"Our subscription plan for the solution has a limitation of bot signatures."
"The onboarding process can be improved a little bit."
"For the topic of improvement, providing some training material is one of my suggestions."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Darktrace is a closed technology, meaning we know very little about how it works, including the architecture, which is significant. As a result, when we implement the system and find we're getting many false positives, we have minimal insight into why it's happening and what we can do to fix it. We don't know how the solution is configured, the criteria for threats to be determined, or the product's inner workings. We understand that they have to ensure privacy and their copyright, but we want to see some documentation or public research into the security Darktrace provides."
"It would be useful if there was a way to check to see if there are certain devices that are not in sync with the solution. I'm not sure if this is an option or not."
"I feel that Darktrace could be improved, particularly in the support aspect which is currently very poor. We need to chase Darktrace instead of them being proactive with us."
"There aren't so many third-party vendor platforms natively integrated with the platform."
"Darktrace could improve by being more user-friendly."
"They just need to work on their price. In terms of features, we are trying to understand all the features that we have. We're still exploring everything that we have so that we can fully utilize it. At this point in time, it is not about the features. It is more about utilization. We're just trying to utilize everything to full capacity."
"Darktrace could improve its features, such as monitoring and detecting ransomware."
"The Darktrace Mobile app needs improvement as it's currently limited in functionality, and the learning AI takes a while to adapt to new devices, flagging new users as threats for up to a month before recognizing them as regular network users."
"The solution could be less expensive."
 

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The prices are slightly 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."
"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 is not that expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution's pricing lacks transparency."
"They are too expensive compared with other vendors."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"We've budgeted about 50,000 Kuwaiti dinars for the solution. That is a yearly operating cost."
"The cost of the solution is expensive for smaller businesses. They will not be able to afford it or might not need this type of security solution."
"The pricing is reasonable."
"If you consider the features and the cost of market leaders, we are satisfied with the pricing."
"The cost is moderate."
"The price of the solution is not cheap. It is not a one-time purchase, there is a subscription that needs to be paid every one to five years depending on your choice. It is expensive but you can reduce the price by only using the services that you want."
