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

"Clover is the best product globally."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Cloudflare DDoS mitigates DDoS attacks."
"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."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"It will take the blow rather than our applications should an attack occur."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Darktrace is very flexible."
"Darktrace has improved our knowledge of abnormal phenomenen which could have potentially be hazardous for the organization."
"I can rate Darktrace's technical support as one of the best products in the world."
"The Enterprise Immune System, Cyber Artificial Intelligence Analyst, and Antigena technology are all very useful aspects of the product."
"The Antigena feature is most valuable. Once it learns your environment, Antigena can step in and block a denial of service attack, a ransomware attack, or just about anything that doesn't belong in the environment. It can detect any type of attack that hits the environment because it understands what normal looks like for the network. It is very useful for an autonomous response."
"Because of all it does, Darktrace is a very good solution, and it doesn't take a lot of time to implement and to get results."
"Darktrace's most valuable features are that it understands the network environment and is able to trace the traffic and alert on anomalies."
"We're very pleased with Darktrace so it is a bit difficult to pinpoint areas for improvement."
"It is stable and reliable."
 

Cons

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Feedback could be enhanced."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Cloudflare DDoS has poor technical support."
"Operating and tuning the product is difficult."
"Our customers no longer use Cloudflare because its service is subpar."
"For the topic of improvement, providing some training material is one of my suggestions."
"It would be helpful if they could recognize incidents and simplify the customer's challenge to identify what is happening."
"The solution could be easier to use."
"There aren't so many third-party vendor platforms natively integrated with the platform."
"As of now, I feel Darktrace can be improved to better detect end device activities, such as laptops or desktops, to bind it with our network."
"The solution would benefit from automation. Currently, you have to know what you are searching for."
"The solution's user interface and stability could be improved."
"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."
"In a shared environment, it doesn't work, and there are still some integration issues."
"The solution could be less expensive."
 

Pricing and Cost Advice

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The prices are slightly expensive."
"The solution is not that expensive."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"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 about $6,000 per quarter."
"The pricing is quite high, estimated at around $350,000 per year."
"I'm unfamiliar with the exact cost, but we have a yearly license and had to pay for Darktrace's services before the deployment. The product is very expensive, so some organizations can't afford to pay the total amount directly, meaning they often seek a partner or pay in installments, which increases the price more."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"The price of Darktrace is high and could be reduced. We pay approximately $30,000 to $54,000 annually."
"I am using a demo of Darktrace for deployment and testing which is free."
"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."
"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."
