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 solution has different options that can be used to differentiate DDoS attacks."
"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."
"Cloudflare is simple to use."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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 best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"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."
"I highly recommend the overall solution to other users and rate it as nine out of ten."
"The most valuable feature of this solution is that it does not require human intervention to eliminate a threat."
"I like the dashboards, which are cool. They are more user-friendly, in my experience. Its learning capabilities are really good."
"I particularly like Antigena and the analytics around the real-time monitoring of our network. I also like its reporting because it has got a seven-day reporting period within the system. Every time you run the reports, it gives you the data about the previous seven days. I like that because it is in real-time. I enjoy reading those reports and getting a very clear and decisive idea of what's happening on my network on a real-time basis. I like the actual real-time monitoring of spoofing and things like that. I also like the user monitoring as well as the network logging capabilities."
"Darktrace is valuable since it offers full packet capture and detailed metadata."
"Regarding the autonomous response feature, I appreciate how it functions within the platform."
"The most valuable feature of Darktrace is the AI that detects abnormal network activity."
"I find it very good in the way that they show the past events, including the attack history."
"It is stable and reliable."
 

Cons

"Operating and tuning the product is difficult."
"Feedback could be enhanced."
"They don't have a person to provide support for customers using the solution under their free plan."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Our customers no longer use Cloudflare because its service is subpar."
"The initial onboarding was causing us some confusion."
"The user interface and the configuration are a bit complex and should be improved or simplified."
"This product needs more in terms of prevention. The detection capabilities work well but once a threat has been detected, Darktrace should work to prevent it from doing anything malicious."
"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."
"The pricing model is a little too high and could be more flexible."
"I would like for the product to work on the endpoints as well. I would like to see enhanced visibility into the endpoints and network but this solution only sits on the network itself."
"The program is quite expensive."
"It would be good if they can include some endpoint protection for remote workers. Nowadays, most people are working remotely. Therefore, they should include some type of sensors that can be installed on the endpoint in order to directly report the main usage and protect remotely. Phone protection will also be a great feature to add to Darktrace."
"The module can improve so that every time it's more intelligent."
"The solution could be less expensive."
 

Pricing and Cost Advice

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution is not that expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution's pricing lacks transparency."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The prices are slightly expensive."
"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 of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"The cost of the solution can be reduced to make it more appealing to customers."
"Darktrace is pricey, but the price is reasonable for what the solution does, and it's comparable to other products."
"It is expensive."
"They are too expensive compared with other vendors."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"It is expensive. I don't have the price for other competitors."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
