Sentiment score
7.8
Companies favor HAProxy for cost-effective traffic management, saving on load balancers, and retaining customers annually with positive ROI.
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.
Subscription models offer clearer ROI due to a more competitive pricing scheme.
 

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
7.1
F5 Advanced WAF support is professional, helpful, but needs quicker responses; higher SLAs offer faster service and better experience.
Sentiment score
7.3
HAProxy's customer service has mixed reviews with suggestions for better documentation, though premium support is appreciated but inconsistent.
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.
If there is a bug, the support is usually understanding and resolves issues.
I have interacted with F5's support, and while I have no major complaints, they could improve.
 

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
7.6
F5 Advanced WAF excels in scalability and adaptability, supporting diverse applications, ideal for medium to large enterprises.
Sentiment score
7.8
HAProxy scales efficiently, supporting diverse loads and thousands of users, adaptable for both small and large business needs.
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.
 

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
8.5
F5 Advanced WAF is praised for stability and reliability, scoring highly in sectors like banking and telecom.
Sentiment score
8.1
HAProxy is highly rated for stability and reliability, though some users occasionally face configuration and compatibility challenges.
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.
 

Room For Improvement

Cloudflare requires improvements in analytics, CDN speed, API, technical support, DNS management, documentation, pricing clarity, and international and reseller support.
F5 Advanced WAF needs easier interfaces, better integration, enhanced support, and improved features for user-friendliness and efficiency.
HAProxy needs better pricing, monitoring, documentation, dashboard functionality, performance stability, and enhanced GUI and TCP session control.
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.
Deployment training for F5 Advanced WAF is lacking and restricts growth by being inaccessible and costly for partners.
 

Setup Cost

Cloudflare offers cost-effective, scalable plans with no setup fees, starting from free for small businesses to enterprise-level solutions.
F5 Advanced WAF is costly but valued for its advanced features, comprehensive protection, and flexibility in high-stakes environments.
HAProxy is free open-source software offering economic benefits, easy setup, and optional affordable extended features for integrated solutions.
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.
Subscription models have competitive pricing, while perpetual licenses involve an upfront higher cost.
The price is affordable and satisfactory.
 

Valuable Features

Cloudflare enhances security, speed, and SEO with easy-to-use features like CDN, SSL, DDoS protection, and centralized management.
F5 Advanced WAF offers comprehensive protection with integration, customization, and features like network intelligence, DDoS prevention, and behavior analysis.
HAProxy offers load balancing, security, customization, scalability, open-source benefits, and efficient traffic management with user-friendly setup and cost savings.
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.
The perpetual license, despite an initial higher cost, lacks transparency regarding support expiration.
It contains the logic of both negative and positive security combined.

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.
Ahmed Moamen - PeerSpot reviewer
Protects applications with versatile authentication features
F5 offers a versatile solution that can be integrated with APM in cases where integration with an external IDB is needed. It is useful for authentication backup if the on-prem directory service is unavailable. Additionally, its WAF functionality is valuable for protecting applications from attacks. It is a versatile and strong solution that's easy to understand and deploy.
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.
