Sentiment score
7.1
HAProxy's open-source load balancer cuts costs, boosts efficiency, improves uptime, reduces staffing, and enhances scalability for users.
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.
Owner at Hga consulting
Recently, they have been under serious attack with major exploits, such as Log4j, affecting Fortinet and Palo Alto, and even Cisco and VMware.
Senior Solutions Architect at EQ2 Technology
AI-based recommendations save on time and money.
Head of Digital Engineering, Management Consultant at Stax Inc.
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.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
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%.

Room For Improvement

Cloudflare WAF needs feature enhancements, better usability, improved support, advanced DDoS protection, and solutions for latency and alerts.
Azure Web Application Firewall needs better reporting, integration, cost plans, and process streamlining for enhanced management and support.

The product can improve by having more multitenancy capability, which is currently not available.
Network Architect at a computer software company with 11-50 employees
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.
Owner at Hga consulting
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.
CTO at PlayNirvana
Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead.
Head of Digital Engineering, Management Consultant at Stax Inc.
The pricing needs improvement, and I think for beginners it will be a little bit complicated, so the ease of use could be enhanced.
Global IT Solutions Specialist at RELIEF INTERNATIONAL INC
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.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
An easier desktop interface to connect to a remote server and make changes on my PC would be beneficial.
DevOps engineer at a tech services company with 1-10 employees
The reloading functionality is effective as it allows soft reloads without interrupting traffic patterns.

Senior Solutions Architect at EQ2 Technology
Sometimes, when opting for a higher SKU, it's not the WAF itself that's costly but the additional requirements.
Head of Digital Engineering, Management Consultant at Stax Inc.
I would place Azure Web Application Firewall at an eight on a scale from one to 10, with one being cheap and 10 being expensive.
Global IT Solutions Specialist at RELIEF INTERNATIONAL INC
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.

Network Architect at a computer software company with 11-50 employees
The best features of Cloudflare Web Application Firewall are multiple, including the WAF, rate limiter, and bot attack protection.
IT Manager at Amla Commerce
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.

Head of Digital Engineering, Management Consultant at Stax Inc.
It is almost impossible to access these assets from outside, requiring a very skilled attacker to obtain asset tokens of a customer using Azure.
Senior Solutions Architect at EQ2 Technology
It integrates effectively with things such as Sentinel and Defender for Cloud, so mostly it's the analytics and now the AI capabilities that have been introduced with Co-pilot.
Global IT Solutions Specialist at RELIEF INTERNATIONAL INC
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.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
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.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
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.

Advanced security reporting has protected high-traffic betting platforms from constant attacks
I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. 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. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

Offers robust analytics and seamless cloud integration with minor room for user interface improvement
The Microsoft support and the analytics are what I appreciate about Azure Web Application Firewall. It integrates effectively with things such as Sentinel and Defender for Cloud, so mostly it's the analytics and now the AI capabilities that have been introduced with Co-pilot. It helps when looking for threats. It reduces issues significantly because the filtering capabilities are high. Given that it's a cloud solution, we have very minimal downtime, especially because we have Microsoft support. On a scale of one to 10, I would give it an eight.

Handles high traffic efficiently and simplifies complex routing with rule-based logic
I think HAProxy is good as it stands now, but I believe there could be improvements. gRPC has recently been implemented, which is great, along with TLS 1.2 and 1.3 support, and HTTP 2.0 is also available. However, I'm unsure about the benchmark of those HTTP 2.0 requests on HAProxy. If there were any other protocol with better performance than HTTP 2.0, or perhaps mTLS and other similar features, including that in HAProxy would be really great. For improvements, I think that during setup and configuration, the steps provided are neat and clear. Anyone can easily install and configure it. There are many kernel tuning parameters also available, which is great. For specific improvement, in terms of logging, I think printing the full object of the request may help, or if there's a way to reference two requests, it would be beneficial to find a complete session history from a logged-in customer, as it would help analyze customer and user analytics.
