ROI

Sentiment score
6.5
Cloudflare users experienced increased performance, security, and cost-effectiveness, leading to improved loyalty and revenue despite difficult ROI calculations.
Sentiment score
7.6
Cloudflare WAF offers essential protection with cost-effective features, supporting various platforms and enhancing website visibility and uptime.
Sentiment score
7.0
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.
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.
 

Customer Service

Sentiment score
7.0
Cloudflare's customer service is quick, but technical support feedback is mixed, with improvement needed in responsiveness and detailed assistance.
Sentiment score
6.3
Cloudflare Web Application Firewall's support is praised for responsiveness and helpfulness, despite challenges with contact and Indian support.
Sentiment score
6.6
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.
I would rate the technical support with Cloudflare as excellent every time I've had to call them.
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.
 

Scalability Issues

Sentiment score
8.1
Users praise Cloudflare for seamless scalability, effective traffic management, easy upgrades, and robust global infrastructure without disruptions.
Sentiment score
7.7
Cloudflare Web Application Firewall excels in scalability and ease of use, supporting large user bases efficiently with minimal management.
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.
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.
HAProxy's scalability is excellent; as our traffic expands, it handles load increases effortlessly.
 

Stability Issues

Sentiment score
7.6
Cloudflare is highly rated for stability and uptime, with few past issues, especially on higher-tier plans.
Sentiment score
8.1
Cloudflare Web Application Firewall is praised for its reliable performance, minimal downtime, and effective security features across industries.
Sentiment score
8.2
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.
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.
 

Room For Improvement

Enhancements needed in Cloudflare: analytics, CDN latency, API integration, user support, DNS, pricing, documentation, server coverage, WAF, and cache.
Cloudflare's Web Application Firewall requires ModSecurity upgrades, improved logging, integration, accuracy, more controls, and better documentation.
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.
Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements.
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.
They need to improve their support because getting a response for basic requests took around 48 hours, which is too long.
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.
 

Setup Cost

Cloudflare offers scalable pricing, from free to enterprise plans, providing significant value especially for mid-sized companies.
Cloudflare's WAF offers competitive pricing from $20 to $10,000, seen as cost-effective but could improve transparency.
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.
The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive.
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.
 

Valuable Features

Cloudflare enhances performance and security with CDN caching, DDoS protection, and an easy-to-use dashboard, benefiting many users.
Cloudflare Web Application Firewall provides scalable DDoS protection, configurable rules, advanced features, and comprehensive support with minimal false positives.
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.
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.
The best features HAProxy offers for my setup are easy configuration, as I don't need to set up many things; I just installed it and write configurations based on my needs.

Featured Reviews

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.
SachidDoshi - PeerSpot reviewer
Offers a huge signature repository and is superiorly effective in mitigating DDoS attacks
The solution's learning curve can still be further reduced, which presently stands at two or three months. The product has a custom rule set that users can modify and manifest as needed. The vendor can probably shorten the learning curve using cutting-edge technologies like AI. The solution provider can also work around the web applications and identify the toolset that needs to be implemented to deploy the solution in less time. The vendor has launched a SASE product that can function with Cloudflare Web Application Firewall, but many improvements are needed in terms of features, such as the web filtering feature, and CASB has not yet been added.
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.
