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

"This solution is easy to understand and easy to configure."
"Cloudflare DDoS mitigates DDoS attacks."
"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"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."
"It will take the blow rather than our applications should an attack occur."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."
"Cloudflare is simple to use."
"We are able to detect a lot of things, actually, and see what is happening in our network."
"One member of staff is enough for deployment and maintenance because Darkforce is AI-driven. It does a lot of things by itself."
"The product can scale."
"It is very easy to work with Darktrace once you know how it works and the type of permissions that you need to get related to the security over a network. The interface is awesome. I'm sure that you have seen Ironman, and you know Jarvis, the computer of Tony Stark. The interface of Darktrace is very similar, and you can see in 3D, like a hologram, the whole network, traffic, and all the traces inside the network. The interface is awesome, and it provides a lot of information. At least for us, it is very easy to handle this interface, get the reports, and do the interpretation of those reports. Darktrace also provides mobile monitoring. With an app on your mobile phone, you can view the information live, which is very useful for area directors and field engineers. Darktrace can be also correlated with any type of big data solution, such as Splunk."
"One thing I appreciate is Antigena Email, which is for email protection."
"I have found the automation and AI features to be valuable. If someone were to come in to the office at midnight and log in, Darktrace would flag it."
"Darktrace's most valuable features are that it understands the network environment and is able to trace the traffic and alert on anomalies."
"The most valuable features of Darktrace are its full capabilities, as you have visibility of everything happening on your network, emails, and SaaS applications."
"It is stable and reliable."
 

Cons

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Lacks a VPN feature to provide a secure connection to the data center."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"Feedback could be enhanced."
"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 tool should provide on-premise versions. Currently, all versions are cloud-based."
"Operating and tuning the product is difficult."
"Darktrace needs to automate the reports of false positives, botnets and everything."
"There are numerous false positives."
"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."
"I did not use the AI features because they should make it more user-friendly which would be a benefit. Additionally, the solution could integrate with more SIEM or SOAR tools."
"It can have more integration with orchestration or event management solutions. They can provide more knowledge or research information for analysts for investigating cases and detecting anomalies in networks."
"Getting logs from different sources can be a challenge."
"The initial setup is more complex and time-consuming than some solutions."
"The management dashboards and the meter dashboards should be more user-friendly and simple to use for easy management."
"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 is somewhere in the middle. I would rate the pricing a seven out of ten."
"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 prices are slightly expensive."
"The solution's pricing lacks transparency."
"Cloudflare Zero Trust Platform's pricing is good."
"The pricing is subscription-based and it is high."
"The solution is about $6,000 per quarter."
"The pricing is reasonable."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."
"The product is expensive."
"It's an expensive solution."
