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

"Cloudflare is simple to use."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare Access is a stable solution."
"Cloudflare, in my opinion, was easy to implement."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"The blocking feature is very good."
"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 DDoS mitigates DDoS attacks."
"The most valuable feature of Darktrace is the AI that detects abnormal network activity."
"It provides a comprehensive cybersecurity solution that monitors my cloud accounts as well as my local network."
"I find it very good in the way that they show the past events, including the attack history, and you are able to visualize all of the attack paths and connectivity to see what's happened."
"I like the Antigena feature in Darktrace, as it offers immediate response and is helpful."
"The active threat dashboard is the most valuable feature of this solution."
"Regarding the autonomous response feature, I appreciate how it functions within the platform."
"Ability to see events and exactly what traffic or website the device had tried to connect to that raised the alert or issue."
"The models, triggers, and alerts are customizable."
"It is stable and reliable."
 

Cons

"Our customers no longer use Cloudflare because its service is subpar."
"Feedback could be enhanced."
"The response time for support must be reduced."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"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."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"They don't have a person to provide support for customers using the solution under their free plan."
"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."
"There is a high ratio of false positive information."
"Its threat analyzer could be better. It should also have agents. They should improve this product by installing agents for the machine to get more visibility. Currently, they are monitoring only the network. They should also monitor the agents from inside. It should also have a better pricing plan because it is an expensive product."
"The initial setup is more complex and time-consuming than some solutions."
"There are still some issues with the network capturing or blocking traffic even after implementing exceptions. It requires more learning in this area."
"A reporting portal could be a great addition to help customize reports."
"This product needs more in terms of prevention."
"Its documentation is not up to the mark. At times, I have a lot of trouble finding a solution. Even when I posted questions on the community chats, it took a lot of time for me to get answers. That's something that can be improved. Darktrace can focus on creating a more interactive community. If there are more people from Darktrace to focus on community chats, it would be better."
"The technical support is not very good."
"The solution could be less expensive."
 

Pricing and Cost Advice

"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 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."
"The solution is not that expensive."
"The solution's pricing lacks transparency."
"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."
"We've budgeted about 50,000 Kuwaiti dinars for the solution. That is a yearly operating cost."
"Darktrace is pricey, but the price is reasonable for what the solution does, and it's comparable to other products."
"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."
"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."
"The solution is about $6,000 per quarter."
"There is an annual license to use Darktrace."
"This solution is expensive."
"It is inexpensive considering what it can do and the competition."
