HA
Owner at Hga consulting
Has helped manage client domains with streamlined access control and threat visibility
I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service. It doesn't pay to try to host your own website.

Chief Business Officer at Sky Express
Provides endless features and can be adapted to every single application that exists in the world
WAF is the most beneficial feature for security posture. Our customers are more than satisfied with the user experience provided by the product. The level of detail of the configuration is the most significant aspect. We can adapt it to every single application that exists in the world. The product helps with the compliance processes.

Information Technology Division Director at Ethiopian Roads Administration
Offers better visibility into user sessions compared to other solutions
Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"New and innovative way to protect the client's data."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"The solution offers the flexibility to control configuration rules."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"Our customers are more than satisfied with the user experience provided by the product."
"The MAS integration for HDX Insight has provided teams with significant visibility into network performance of the user's connection."
"The solution is extremely stable."
"Load Balancing and SSL offloading are key features."
"It allows students to access required software for their studies."
"The most valuable features are for the ADMs and the overall monitoring environment."
"Content Redirection and SSO integration with Citrix XenApp/XenDesktop. The GUI was wonderful."
"The stability is good. If there is a problem, the load will be shifted to other sites automatically, which has been a good experience for us."
"The web application firewalling component is a powerful feature."
 

Cons

"In the last two years, there has been a certain amount of downtime when using the VDM."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"Latencies are always a problem."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"The solution could be more user-friendly."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"The tool must be simplified."
"I think there is always room for improvement in this type of solutions. For example, I think the GUI should be easy to understand."
"Should offer more flexible cost-effective licensing for small to medium sized organizations."
"Native integration needs to be improved. You cannot build ISE codes natively. For DevOps, integration would be very helpful because it would be a lot simpler from an operational standpoint."
"Their upgrades are not very backward compatible, and sometimes they mess up."
"The licensing model and technical support of the solution could be improved."
"It can be difficult to setup."
"The main areas for improvement would be around documentation and support. If a feature can be used in two or three ways, show that feature being used in all of those ways. Documentation seems to only cover the primary use case and leaves you to either run through trial and error or consult the user community. In terms of support, I have never actually had them solve any of my issues. I have always solved them myself and then provided the resolution to support."
"Maybe creating policies with simple regular expressions."
 

Pricing and Cost Advice

"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"There are no additional costs beyond the standard licensing fees."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The cost primarily depends on the size of the organization."
"I give the price a five out of ten."
"We don't have any issues with the price."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"The tool is cheap."
"It's not for startups or SOHO."
"It all depends on the features that will be used and the number of accesses."
"I do not have any experience with the pricing of the product."
"After deployment, Citrix Netscaler shifted to a subscription-based license scheme for support, which is slightly more expensive."
"There isn't much of a difference between the cost of Citrix and that of other similar solutions."
"The price for Citrix ADC here in Mexico was good, when you compare it with F5 and Radware."
"Price-wise, I feel that the solution is a little bit expensive."
"We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them."
