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

"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"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."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare DDoS mitigates DDoS attacks."
"Cloudflare is simple to use."
"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."
"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."
"The product can scale."
"I find the complete portfolio to be excellent."
"I have found the most valuable features to be artificial intelligence for cybersecurity, advanced machine learning capabilities, enterprise Immune System, Antigena Network, and Antigena Email. The way the solution detects the threat over the network before it spreads is very good. It notifies you of what the threat is exactly doing and gives you all the details about the execution of that application that had created the threat over your network."
"The most valuable feature is that it gives us visibility of rogue traffic that is on the network."
"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."
"Ability to see events and exactly what traffic or website the device had tried to connect to that raised the alert or issue."
"The Dynamic Threat Dashboard is very nice, as it lists all of your threats and rates them, and then you can choose whether to investigate further."
"The most valuable feature of Darktrace and the most valuable feature is the artificial intelligence module because that is the tool that determines automatically if there is any risk or not in the network."
"It is stable and reliable."
 

Cons

"Operating and tuning the product is difficult."
"For the topic of improvement, providing some training material is one of my suggestions."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The initial onboarding was causing us some confusion."
"The response time for support must be reduced."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"The initial onboarding was causing us some confusion."
"They just need to make it a little bit more accurate as far as their alerts are concerned. It does generate some false positives that you have to tune."
"I would like to see more protection in the endpoint. Especially because we have a lot of people using VPNs. If they would improve end point security, it would give more control there."
"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."
"The solution would benefit from automation. Currently, you have to know what you are searching for."
"The stability isn't good but I like the product."
"It's quite expensive to have."
"The dashboard and reporting for this solution could be improved as it is currently complex. The GUI for this solution could also be improved."
"The pricing needs improvement."
"The solution could be less expensive."
 

Pricing and Cost Advice

"The prices are slightly 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."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The solution is not that expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"This solution is expensive."
"The solution is about $6,000 per quarter."
"All of the other modules, such as the licensing modules, are on par. It's one for one."
"There is an annual license to use Darktrace."
"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."
"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."
"The pricing is quite high, estimated at around $350,000 per year."
"We've budgeted about 50,000 Kuwaiti dinars for the solution. That is a yearly operating cost."
