Find out in this report how the two Distributed Denial-of-Service (DDoS) Protection solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI.
My experience with the pricing or licensing of Cloudflare Web Application Firewall is that many features can be accessed for free, so the pricing is definitely reasonable.
Operational efficiency has improved; we no longer have staff consistently monitoring backend servers during deployment or scaling events, as HAProxy's health checks and hitless reloads allow us to push changes with minimal manual intervention.
This resulted in a drastic decrease in costs and, at the same time, the accuracy of the hits coming on HAProxy was almost around 100% or 99.99%.
I estimate seeing a return on investment with HAProxy, as it significantly reduced staff requirements and enhanced scaling capabilities, particularly when transitioning from NGINX, which faced issues.
I would rate the technical support with Cloudflare as excellent every time I've had to contact them.
The technical support of Cloudflare Web Application Firewall rates between five and seven at maximum.
Since we are utilizing the open-source edition, community forums, mailing lists, and GitHub have been invaluable, with typically someone having encountered the same problems we faced.
My interactions with HAProxy's customer support were limited, but the feedback from my team indicated satisfactory service.
The scalability of Cloudflare Web Application Firewall rates between 8 to 9, as it depends upon the use cases and what exactly the client needs.
We manage an automatic load balancing feature where we add HAProxy servers dynamically behind the application load balancer to handle more traffic.
HAProxy's scalability is excellent; as our traffic expands, it handles load increases effortlessly.
For scalability, HAProxy meets my needs, supporting our initial horizontal scaling and then adapting to vertical scaling in a VMware environment.
The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10.
This reliability serves as a key reason for our choice, providing us with confidence even when faced with heavy traffic.
The hot reload feature of HAProxy also really helped us so that we never had to shut it down to reload it.
We have reduced a lot of servers, replacing them with one or two HAProxy servers which deliver better performance, accuracy, and an almost 100% success rate with requests.
The product can improve by having more multitenancy capability, which is currently not available.
I think they're doing a good job with DNS and as support for any domains that I create or that my clients create, it's mandatory for me to ensure they have Cloudflare as their DNS provider.
And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network.
The configuration syntax is powerful yet can become overwhelming for newcomers; a more beginner-friendly interface or a native GUI without relying on third-party tools would ease the onboarding process.
An easier desktop interface to connect to a remote server and make changes on my PC would be beneficial.
The reloading functionality is effective as it allows soft reloads without interrupting traffic patterns.
Since we use the open-source edition, there are no licensing fees, with the main cost being the infrastructure running on EC2 instances in AWS, which helps maintain low expenses.
Setting up HAProxy didn't cost anything for me.
The pricing remains competitive compared to other vendors.
The custom rules and the geo-redundant geographical rule feature, which allows me to implement geographical rules for customers, add significant value.
The best features of Cloudflare Web Application Firewall are multiple, including the WAF, rate limiter, and bot attack protection.
Cloudflare Web Application Firewall's advanced reporting and analytics tools add a layer that we're able to visualize and see before it actually hits the local firewall.
By moving all SSL termination to the load balancer, I now manage certificates in a single place, and I can also utilize Let's Encrypt with HAProxy's built-in ACME support, making renewal automatic.
HAProxy positively impacted our organization by exceeding scalability expectations, initially projected at 200k requests but ultimately handling over 15 million transactions per second without any issues.
As a production engineer at that time, I definitely wanted to ensure that the system could handle massive connections, especially since we operated an e-commerce platform where we could not lose any customer calls.

Cloudflare Web Application Firewall's intuitive dashboard enables users to build powerful rules through easy clicks and also provides Terraform integration. Every request to the WAF is inspected against the rule engine and the threat intelligence curated from protecting over 27 Million websites. Suspicious requests can be blocked, challenged or logged as per the needs of the user while legitimate requests are routed to the destination, agnostic of whether it lives on-premise or in the cloud. Analytics and Cloudflare Logs enable visibility into actionable metrics for the user.

Reviews from Real Users
“Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind.” - Nathanel S., Platform Architect at SES
“I use HAProxy for individuals who can not buy low balancers. I built NFV in a box and send individuals a pathway into an HAProxy VM. The setup was not difficult; it usually takes a day to complete for a VPC. When it comes to pricing, HAProxy is free.” - Nasir O., Network & Cloud Architect at Koala Compute Inc.
