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 part of the Zero Trust philosophy."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"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 blocking feature is very good."
"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."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare Access is a stable solution."
"In terms of features, the data or information they collect and unsupervised machine learning are very valuable. Its unsupervised machine learning has reduced our team's effort. Both Darktrace and Vectra work on unsupervised machine learning that learns the behavior or develops a profile on its own, which allows our security team to do some other tasks rather than spending time on Darktrace or Vectra. Because of unsupervised machine learning, its detection capability is quite good. Along with that, if we utilize the integration feature properly, the automated incident response capability of Darktrace is quite useful."
"Darktrace is very stable, and I would rate its stability a ten out of ten."
"The most beneficial feature in Darktrace is identifying phishing emails with the help of the AI engine and machine learning."
"Darktrace is valuable since it offers full packet capture and detailed metadata."
"The most valuable part of the product is the whole package, as the features included in the Enterprise Immune System are complete and effective and its detection engine is ridiculously good."
"The most valuable feature in Darktrace is that it gives me a comprehensive, detailed view of my network and whatever is happening inside it."
"I would 100% recommend Darktrace."
"Based on our experience with DarkTrace, I would advise that if they are comparing prices, ROI and everything, I think Darktrace is better than FireEye."
"It is stable and reliable."
 

Cons

"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"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."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Our customers no longer use Cloudflare because its service is subpar."
"The onboarding process can be improved a little bit."
"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."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"For the topic of improvement, providing some training material is one of my suggestions."
"The initial setup is more complex and time-consuming than some solutions."
"The only thing that I can think of that would improve it would be if they had a better visualization and a reporting portal."
"The interface is too mathematical and it should be simplified."
"The solution's user interface and stability could be improved."
"Its threat analyzer could be better. It should also have agents."
"The pricing needs improvement."
"The solution can improve the reporting. Currently, it only runs weekly and the reporting is complex."
"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 solution could be less expensive."
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution is not that expensive."
"The prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"It's an expensive solution."
"We've budgeted about 50,000 Kuwaiti dinars for the solution. That is a yearly operating cost."
"The price of Darktrace is high and could be reduced. We pay approximately $30,000 to $54,000 annually."
"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"The pricing is very flexible for Darktrace. Sometimes, a customer does not have the appropriate budget, but Darktrace can handle that. They offer monthly payments, so the customer can acquire the solution very easily."
"It is inexpensive considering what it can do and the competition."
"The pricing is reasonable."
