Comparison Buyer's Guide

Executive Summary

Review summaries and opinions

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

ROI

Sentiment score
6.5
Cloudflare enhanced speed, security, and data protection, providing significant ROI and improved operations and client satisfaction for businesses.
Sentiment score
7.9
HAProxy offers cost-effective traffic management, enhanced efficiency, and high ROI through streamlined processes and reduced manual intervention.
WordPress security can be tricky, and that's where Cloudflare can be absolutely helpful for small businesses.
For the small project I was working on, using the basic tier provided a huge improvement at zero cost.
In terms of return on investment with Cloudflare, it costs my time to set them up, but basically once they're set up, it's done.
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.
 

Customer Service

Sentiment score
7.0
Cloudflare's customer service is efficient for paying users, but responses can vary in speed and effectiveness for others.
Sentiment score
6.9
HAProxy's customer service is swift and effective, but open-source support lacks the comprehensiveness of enterprise alternatives.
This would help us address issues promptly, especially during unforeseen events like DDoS attacks.
Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model.
The key factor is the language in which the support is offered, which, in this case, is in Thai.
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.
 

Scalability Issues

Sentiment score
8.1
Cloudflare is praised for seamless scalability, managing enterprise-level traffic efficiently and earning high customer satisfaction during peak events.
Sentiment score
7.8
HAProxy is praised for its scalability, efficiency, and flexibility, handling thousands of connections and supporting mid-sized deployments seamlessly.
It is a SaaS tool, but the fact that they have workloads deployed across the world proves that it is a highly scalable tool.
The tool offers very good performance, even during high-traffic periods.
I rate the solution’s scalability an eight out of ten.
HAProxy's scalability is excellent; as our traffic expands, it handles load increases effortlessly.
 

Stability Issues

Sentiment score
7.6
Cloudflare is widely regarded as stable and reliable, with improvements noted in uptime and performance on higher plans.
Sentiment score
8.1
HAProxy is highly stable, reliably managing heavy traffic with minimal downtime, efficient support, and consistent functionality improvements.
For DDoS protection, I would not recommend Cloudflare.
I rate the solution’s stability an eight out of ten.
The service is very stable with no impacts during high-traffic periods.
This reliability serves as a key reason for our choice, providing us with confidence even when faced with heavy traffic.
 

Room For Improvement

Cloudflare requires improvements in analytics, CDN speed, API, technical support, DNS management, documentation, pricing clarity, and international and reseller support.
HAProxy needs better GUI, dynamic configuration, user-friendly logging, REST API, cloud integration, security, and community features.
There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features.
Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor.
The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client.
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.
 

Setup Cost

Cloudflare offers cost-effective, scalable plans with no setup fees, starting from free for small businesses to enterprise-level solutions.
HAProxy is cost-effective, praised for simple licensing, robust features, and valued by enterprises despite requiring expertise for setup.
That's where Cloudflare shines for smaller businesses – it's ten times cheaper than Akamai.
I find it to be cheap.
I think they should consider reevaluating the pricing for support, as it can be quite high.
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.
 

Valuable Features

Cloudflare enhances security, speed, and SEO with easy-to-use features like CDN, SSL, DDoS protection, and centralized management.
HAProxy is praised for its excellent load balancing, reliability, customization, scalability, advanced traffic rules, and open-source integration.
The most valuable features of the solution are performance and security.
Techniques like minification and image compression reduce the size of assets, leading to better performance and faster user load times.
The solution has been able to compare it to the market, and I think the product has taken great strides in automating quite a bit of things, and they use a lot of AI.
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.

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Mehdi El Filahi - PeerSpot reviewer
Useful for for small and quick load-balancing tasks
What I like best about the product is its simplicity and speed. When you need to set up a load balancer quickly, HAProxy offers options like sticky sessions and round-robin. It's also fast to configure, including adding SSL for security. While it may have fewer options than other solutions like F5, HAProxy gets the job done for basic load-balancing tasks. The reliability features of HAProxy were particularly useful in a scenario where I needed to test load balancing between two Tomcats. Since these domains were inaccessible, I set up a third Docker with HAProxy, which had access to the Tomcat domains. I then configured HAProxy to handle the load balancing. This setup allowed the client to interact with HAProxy. The solution's integration with other elements is easy.
