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

"Enables me to work from two locations."
"It will take the blow rather than our applications should an attack occur."
"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 Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare DDoS mitigates DDoS attacks."
"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."
"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."
"The blocking feature is very good."
"Its most valuable feature is its ability to identify malicious connected IPs from outside and the attacks that get through to the inside."
"Technical support is great. They are very responsive and helpful."
"It's beneficial to me and I can see that with more time and energy put into optimizing it and personalizing the unit, it can be much more powerful than the way I am using it now."
"Regarding the autonomous response feature, I appreciate how it functions within the platform."
"The autonomous response is also highly designed in Darktrace."
"The most valuable feature is that it gives us visibility of rogue traffic that is on the network."
"I particularly like Antigena and the analytics around the real-time monitoring of our network."
"Darktrace is extremely stable."
"It is stable and reliable."
 

Cons

"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."
"They don't have a person to provide support for customers using the solution under their free plan."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The initial onboarding was causing us some confusion."
"Cloudflare DDoS has poor technical support."
"Operating and tuning the product is difficult."
"Feedback could be enhanced."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The main portal needs improvement as it is difficult to use."
"It takes time to go through the interface and pick up things. If it were a more straightforward interface, then it would free up time."
"The management user interface needs improvement."
"I would like to see a feature where the tool ingests information from an anti-malware product that is present at the endpoint."
"This product needs more in terms of prevention."
"The pricing is based on the number of endpoints, so the program is rather expensive."
"The user interface and the configuration are a bit complex and should be improved or simplified."
"It can have more integration with orchestration or event management solutions. They can provide more knowledge or research information for analysts for investigating cases and detecting anomalies in networks."
"The solution could be less expensive."
 

Pricing and Cost Advice

"The prices are slightly expensive."
"The solution is not that expensive."
"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."
"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The pricing is expensive. It costs over $100,000 a year."
"We've budgeted about 50,000 Kuwaiti dinars for the solution. That is a yearly operating cost."
"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."
"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."
"I am using a demo of Darktrace for deployment and testing which is free."
"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."
"The price of the solution is not cheap. It is not a one-time purchase, there is a subscription that needs to be paid every one to five years depending on your choice. It is expensive but you can reduce the price by only using the services that you want."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
