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

"It will take the blow rather than our applications should an attack occur."
"Cloudflare Access is part of the Zero Trust philosophy."
"The blocking feature is very good."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, 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."
"Cloudflare, in my opinion, was easy to implement."
"The most valuable feature of Darktrace is the AI that detects abnormal network activity."
"The active threat dashboard is the most valuable feature of this solution."
"The models, triggers, and alerts are customizable."
"The most valuable feature is that it works autonomously."
"I highly recommend the overall solution to other users and rate it as nine out of ten."
"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."
"The most valuable features of Darktrace are its full capabilities. You have visibility of everything."
"I can rate Darktrace's technical support as one of the best products in the world."
"It is stable and reliable."
 

Cons

"Lacks a VPN feature to provide a secure connection to the data center."
"The initial onboarding was causing us some confusion."
"Cloudflare DDoS has poor technical support."
"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"Our subscription plan for the solution has a limitation of bot signatures."
"Operating and tuning the product is difficult."
"The response time for support must be reduced."
"One thing that I would like to look at going forward is to have a fully automated network infrastructure that is monitored automatically real-time, and that gives me this kind of capability where I would be able to look at my network at any given time and see the state of my network. With Darktrace, at the moment, I have to almost put in a date and tell them that want you to give me data from this date to this date. I don't want that. I want a fast solution in which it doesn't matter when I log into the application. Whenever I log in, I must be able to see my network and run a report. In other words, if I go in now and I say, "Give me a full report of what happened today, it must be able to give me that. It mustn't just be limited to a seven-day period, for argument's sake. It must be able to give me real-time and day-to-day tracking of what has happened within my network."
"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."
"Although we haven't detected any network threats since implementing Darktrace, we are unsure of its efficacy. It would be beneficial if the solution could offer additional details to the user regarding any potential or prevented threats. Additionally, there could be better search tools and integration."
"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."
"The management dashboards and the meter dashboards should be more user-friendly and simple to use for easy management."
"One thing I would like is for Darktrace to flag SMB traffic more accurately. Currently, it only flags that SMB traffic has occurred, but it doesn't specify which file was being transferred. This makes it difficult to investigate incidents involving SMB traffic, as we don't have concrete evidence of what was being sent."
"The pricing is a bit high for the region."
"It's quite expensive to have."
"The solution could be less expensive."
 

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."
"Cloudflare Zero Trust Platform's pricing is good."
"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 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."
"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."
"The pricing is quite high, estimated at around $350,000 per year."
"This solution is expensive."
"Darktrace is pricey, but the price is reasonable for what the solution does, and it's comparable to other products."
"They are too expensive compared with other vendors."
"The pricing is subscription-based and it is high."
"The price of Darktrace is high and could be reduced. We pay approximately $30,000 to $54,000 annually."
"It is expensive."
