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.

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 is by far the most effective solution that I have come across."
"Cloudflare is simple to use."
"Cloudflare Access is part of the Zero Trust philosophy."
"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"Enables me to work from two locations."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"This solution is easy to understand and easy to configure."
"It provides a comprehensive, detailed view of network activity and whatever is happening inside it."
"The autonomous mode, which is the Antigena AI response, is particularly valuable."
"It's a very stable product."
"The most valuable feature is the solution's ability to trim out the false positives and point your attention to the real important stuff."
"Darktrace is extremely stable."
"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 platform has many modules, and each module examines a different situation in the behavior."
"Its AI technology supports cybersecurity by learning my environment and accurately responding to threats."
"It is stable and reliable."
 

Cons

"Cloudflare DDoS has poor technical support."
"Lacks a VPN feature to provide a secure connection to the data center."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The initial onboarding was causing us some confusion."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"They don't have a person to provide support for customers using the solution under their free plan."
"For the topic of improvement, providing some training material is one of my suggestions."
"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."
"It would be good if they can include some endpoint protection for remote workers. Nowadays, most people are working remotely. Therefore, they should include some type of sensors that can be installed on the endpoint in order to directly report the main usage and protect remotely. Phone protection will also be a great feature to add to Darktrace."
"Darktrace needs significant improvement in its notification capabilities."
"It would be helpful if they could recognize incidents and simplify the customer's challenge to identify what is happening."
"Darktrace needs to automate the reports of false positives, botnets and everything."
"A reporting portal could be a great addition to help customize reports."
"We'd like threat hunting, and we'd like to see a global solution that can automate vulnerability scans. I know it is something they are working on."
"The price point for the product was too high for what our possible use case could be."
"The solution would benefit from automation. Currently, you have to know what you are searching for."
"The solution could be less expensive."
 

Pricing and Cost Advice

"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution's pricing lacks transparency."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The prices are slightly expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that expensive."
"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."
"Darktrace is expensive. You can pay for the license yearly."
"When it comes to large installations, it can be expensive, but for small accounts it's fine."
"There is an annual license to use Darktrace."
"It's an expensive solution."
"It is expensive."
"It is inexpensive considering what it can do and the competition."
"They are too expensive compared with other vendors."
