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.

Consistent threat hunting and anomaly detection deliver valuable insights for network security management
In terms of improvement for Darktrace, pricing is the main concern. Pricing bothers me and this is one of the major factors when choosing a solution. When we get feedback from customers, that's the only felt need. When we factor in Darktrace, we do it only limited. We put it on where the perimeters and connections are, but still, some gray areas are left out, especially if we have multiple branches. We need Darktrace on each branch to get the data out, and I suggest having some kind of a centralized product that gets data from multiple sources to aggregate and provide the data.

Cons

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The initial onboarding was causing us some confusion."
"Our subscription plan for the solution has a limitation of bot signatures."
"Operating and tuning the product is difficult."
"In the next version, I'd like to see penetration testing."

"The cost is a bit on the higher side."
"The solution could be easier to use."
"The pricing is based on the number of endpoints, so the program is rather expensive."

"The solution could be less expensive."
 

Pricing and Cost Advice

"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 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 solution's pricing lacks transparency."
"The prices are slightly expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"The pricing is expensive. It costs over $100,000 a year."
"The tool's pricing is costly."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"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."
"It is expensive."
"It is a very expensive product."
"It is expensive. I don't have the price for other competitors."
"The pricing is subscription-based and it is high."
