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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"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."
"Enables me to work from two locations."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"It is a stable solution."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Cloudflare, in my opinion, was easy to implement."
"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."
"A very useful feature in Darktrace for real-time threat analysis is the packet inspection that analyzes the packet traffic in real time."
"The autonomous response is also highly designed in Darktrace."
"The solution is stable. We've never had any problems with it."
"The most valuable feature has been the behavioral analytics that allows us to monitor all the traffic."
"The active threat dashboard is the most valuable feature of this solution."
"The main valuable feature is that we don't need a lot of analysts. With few analysts, we have all the network monitored, 24/7."
"Its AI technology supports cybersecurity by learning my environment and accurately responding to threats."
"It is stable and reliable."
 

Cons

"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."
"Our subscription plan for the solution has a limitation of bot signatures."
"Feedback could be enhanced."
"For the topic of improvement, providing some training material is one of my suggestions."
"The initial onboarding was causing us some confusion."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The onboarding process can be improved a little bit."
"The Darktrace Mobile app needs improvement as it's currently limited in functionality, and the learning AI takes a while to adapt to new devices, flagging new users as threats for up to a month before recognizing them as regular network users."
"One area for improvement is the alerting system, which generates too many alerts and becomes labor-intensive for organizations not equipped with enough personnel in their SOC."
"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."
"Darktrace would tell you, for example, if there was a ransomware attack, but it wouldn't stop the attack."
"The cost of the solution is quite high."
"There are still some issues with the network capturing or blocking traffic even after implementing exceptions. It requires more learning in this area."
"Its documentation is not up to the mark. At times, I have a lot of trouble finding a solution."
"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 prices are slightly expensive."
"The solution is not that expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Cloudflare Zero Trust Platform's pricing is good."
"The pricing is somewhere in the middle. I would rate the pricing a seven 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 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 product is expensive."
"They are too expensive compared with other vendors."
"The solution is about $6,000 per quarter."
"We had an issue with pricing initially and had to cancel some of the features of the projects to fit the budget. I would like to see pricing that is not broken up into parts so that we can buy the whole package once. Darktrace is more expensive than an average solution, but it's functionality won't match that of an average solution."
"This solution is expensive."
"The cost is moderate."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"The pricing is expensive. It costs over $100,000 a year."
