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.

Protects web applications with comprehensive security features
All features are valuable. In a multi-cloud or distributed cloud, there are many protection possibilities from data to web application or API protection, including bot mitigation. This is a comprehensive package for web application security. The main benefit is Web App Security, offering a complete security package from DDoS to web application firewall, API protection, and bot mitigation.

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

"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"The DDoS protection is the most valuable aspect of the solution."
"I like Cloudflare's application gateway and DDoS protection."
"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."
"Generally, I am satisfied with this product."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"Cloudflare makes it easier for me to handle and set up DNS for multiple users and multiple clients, and basically go in and access their account, make the changes they need, and it's a one-stop shop."
"F5 is known for being the best load balancer in the market. Customers with an existing module can easily adopt additional modules without investing in new hardware."
"The main benefit is Web App Security, offering a complete security package from DDoS to web application firewall, API protection, and bot mitigation."
"In a multi-cloud or distributed cloud, there are many protection possibilities from data to web application or API protection, including bot mitigation."
"Available on any device and can be accessed on a wide area network."
"From a security standpoint, It is a comprehensive solution in a single box."
"Easy, user-friendly setup with content switching and integrated caching features."
"The most valuable feature is the content switching."
"Content Redirection and SSO integration with Citrix XenApp/XenDesktop. The GUI was wonderful."
"I can turn on features without actually owning a license. I can test them out, I can use them for a while, and then I can be licensed up. That's awesome. I don't have to have a license immediately before I can start to deploy things rapidly, rapid deployment is a plus."
"The solution is extremely stable."
"The solution is easy to work with and manage."
 

Cons

"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."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"Cloudflare's console should be made more user-friendly."
"The solution could work at being less expensive. It costs a lot to use it."
"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"The solution could be more user-friendly."
"The main issue is integration with other parts or products of F5, like on-premise WAF."
"The main issue is integration with other parts or products of F5, like on-premise WAF. There are some problems, mainly from the perspective of implementation and customer expectations, which sometimes differ from reality."
"The pricing could be adjusted to better meet the needs of typical customers in regions like Poland, where the product is considered too expensive."
"Too many bugs in the software and it's always difficult when you need to update."
"Overall the price of Citrix ADC could be more competitive."
"This is an expensive solution."
"In terms of what could be improved, I would say the user interface because sometimes it can be complicated."
"Citrix should offer a demo or free-trial version of NetScaler. Several other vendors do, but Citrix does not. Pricing should also be more readily available."
"Some of our customers have questioned the security of this solution lately, wondering whether it is safe or not, so enhancements in this respect would be good."
"Their upgrades are not very backward compatible, and sometimes they mess up."
"The technical support has room for improvement."
 

Pricing and Cost Advice

"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"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 solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"There are no additional costs beyond the standard licensing fees."
"The product's pricing is cheap."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
Information not available
"NetScaler does the same thing as an F5 and it's cheaper."
"Citrix Web App and API Protection are in the middle when we talk about pricing and licensing"
"It is very pricey, but we get it. If you need the best, money shouldn't be a problem."
"You can do CapEx and then a yearly monthly fee, or you can do a subscription model, whether that's one month, month-to-month, or three-year subscription model."
"Licensing is adequate. I wanted to have a more prominent license, but until I do they don't give enough support. The additional cost would be too much."
"After deployment, Citrix Netscaler shifted to a subscription-based license scheme for support, which is slightly more expensive."
"You get the value for your money. There aren't any hidden fees."
"F5 BIG-IP is much more expensive than Citrix ADC. For example, If we choose two platforms, Citrix ADC, 3000 version, and we choose F5, F4200 version. F5 BIG-IP has connections, timers, and throughput similar to Citrix ADC, but the price is very expensive."
