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.

Monitoring has improved data loss detection and now spots abnormal internal file transfers quickly
In my understanding, the best feature Darktrace offers is the identification of copying files, which acts as a DLP, and it is a main concern for companies because users sometimes copy data outside without knowing, especially those without a technical background. When I mention the DLP-like feature and file copying detection, the alerts have been very timely, as we get an alert within a couple of minutes, which is excellent. Even if some developers are working after hours and copying files, our SOC team detects this, and most of the time they call us so we can identify the users. The alerts are quite accurate and proactive.

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

"Cloudflare Access is a stable solution."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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 DDoS mitigates DDoS attacks."
"The solution is stable. We've never had any problems with it."
"The product offers us a very good user interface and we've found the network visibility to be very good so far."
"Darktrace is very useful for us because it has a large number of models for detecting threats."
"Its AI technology supports cybersecurity by learning my environment and accurately responding to threats."
"Darktrace is very stable, and I would rate its stability a ten out of ten."
"DT console and alerting system allow getting detailed information about the behavior of users and malicious external or internal threats."
"It's a very stable product."
"Darktrace provides better visibility into network risks, allowing you to take preemptive action against risky user behavior."
"It is stable and reliable."
 

Cons

"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."
"Our customers no longer use Cloudflare because its service is subpar."
"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"Operating and tuning the product is difficult."
"Feedback could be enhanced."
"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."
"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."
"In terms of improvements, fine-tuning is the area where we have to spend some time because it works on unsupervised machine learning."
"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."
"The solution can improve the reporting. Currently, it only runs weekly and the reporting is complex."
"Darktrace could improve its features, such as monitoring and detecting ransomware."
"Darktrace could expand into EDR (endpoint detection and response) and combine it with its network detection."
"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."
"The initial setup is more complex and time-consuming than some solutions."
"The solution could be less expensive."
 

Pricing and Cost Advice

"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."
"Cloudflare Zero Trust Platform's pricing is good."
"The prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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."
"The solution is about $6,000 per quarter."
"Darktrace is quite an expensive solution."
"Darktrace is expensive. You can pay for the license yearly."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"The product is expensive."
"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."
"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."
"If you consider the features and the cost of market leaders, we are satisfied with the pricing."
