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

"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"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."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare DDoS mitigates DDoS attacks."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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."
"The blocking feature is very good."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"We're very pleased with Darktrace so it is a bit difficult to pinpoint areas for improvement."
"It's beneficial to me and I can see that with more time and energy put into optimizing it and personalizing the unit, it can be much more powerful than the way I am using it now."
"It is autonomous, so it learns; it uses algorithms and AI to learn the common behavioral patterns on the network, and it is able to identify threats based on abnormal patterns."
"It provides a comprehensive, detailed view of network activity and whatever is happening inside it."
"The most valuable features of Darktrace are its full capabilities, as you have visibility of everything happening on your network, emails, and SaaS applications."
"Its most valuable feature is its ability to identify malicious connected IPs from outside and the attacks that get through to the inside."
"The most valuable feature in Darktrace is that it gives me a comprehensive, detailed view of my network and whatever is happening inside it."
"They've worked hard to be the top security control in terms of AI and machine learning, and their product works well."
"It is stable and reliable."
 

Cons

"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The onboarding process can be improved a little bit."
"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."
"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."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"I think there is some MSSP missing."
"The solution would benefit from automation. Currently, you have to know what you are searching for."
"In terms of improvements, fine-tuning is the area where we have to spend some time because it works on unsupervised machine learning. It would be good if they can improve their algorithm or technical functionality to reduce the fine-tuning effort. They can also come up with something at the endpoint level. So far, Darktrace has been a network detection response (NDR) solution. It does not offer much at the endpoint level or on user-client devices or servers. There should be more visibility at the endpoint level. It would be good to have the detection and response at the endpoint level by Darktrace. It should also have integration with an agile environment so that we can have continuous development and continuous integration in the application development environment. This is currently not there. It should also have internet-facing platform visibility, which is currently missing. They also need to improve the reporting and management dashboards. Currently, these are not so easy for a non-technical person. All these features would make Darktrace much better, and they would also be helpful in selling more solutions."
"They just need to make it a little bit more accurate as far as their alerts are concerned. It does generate some false positives that you have to tune. You have to do a lot of tuning when you first get it because of the false positives, but once it is all tuned up and ready to go, it will do its thing from there."
"They are too expensive compared with other vendors."
"I did not use the AI features because they should make it more user-friendly which would be a benefit."
"I was under impression that Darktrace's automatic blocking would be an out-of-the-box feature, but we had to integrate it with our firewall to get it to block automatically. The salesperson should be upfront and explain that you need to integrate it with your network. I would also like to see more reporting on risk. Banks in my region want to see at a glance the risk level of various assets."
"The solution's user interface and stability could be improved."
"The solution could be less expensive."
 

Pricing and Cost Advice

"The solution is not that expensive."
"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."
"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."
"The prices are slightly expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution's pricing lacks transparency."
"The pricing is a little high compared to the competition."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"The pricing is reasonable."
"There is an annual license to use Darktrace."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"The cost of the solution can be reduced to make it more appealing to customers."
"This solution is expensive."
"The tool's pricing is costly."
