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 is by far the most effective solution that I have come across."
"The blocking feature is very good."
"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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."
"Cloudflare DDoS mitigates DDoS attacks."
"Clover is the best product globally."
"The platform has many modules, and each module examines a different situation in the behavior."
"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."
"The investigative part of Darktrace is valuable, especially the automation features. It allows setting up checks and provides guidance on mitigating situations, which is very useful. There are different modules that you can add to the console for protection."
"I am impressed with the product's ability to give insights into network traffic."
"It is autonomous. So, it learns. It uses algorithms and AI to learn the common behavioral patterns on the network, and it is able to identify threats based on abnormal patterns."
"The most beneficial feature in Darktrace is identifying phishing emails with the help of the AI engine and machine learning."
"It provides a comprehensive cybersecurity solution that monitors my cloud accounts as well as my local network."
"The solution is stable. We've never had any problems with it."
"It is stable and reliable."
 

Cons

"Our customers no longer use Cloudflare because its service is subpar."
"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."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The response time for support must be reduced."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The onboarding process can be improved a little bit."
"The initial onboarding was causing us some confusion."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"The pricing is expensive. It costs over $100,000 a year."
"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."
"Darktrace requires numerous configurations. It would be beneficial if the configuration could be made simpler."
"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."
"This product needs more in terms of prevention."
"The price point for the product was too high for what our possible use case could be."
"It would be good if they can include some endpoint protection for remote workers."
"The interface and dashboards could be improved for ease-of-use."
"The solution could be less expensive."
 

Pricing and Cost Advice

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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 not that expensive."
"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 solution's pricing lacks transparency."
"The prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Our customers feel that the price of Darktrace is quite high compared to other solutions."
"I am using a demo of Darktrace for deployment and testing which is free."
"Darktrace is quite an expensive solution."
"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."
"The cost of the solution is expensive for smaller businesses. They will not be able to afford it or might not need this type of security solution."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
