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 users experienced increased performance, security, and cost-effectiveness, leading to improved loyalty and revenue despite difficult ROI calculations.
Sentiment score
3.9
Azure Web Application Firewall offers cost-efficiency through reduced administration, AI enhancements, and competitive pricing compared to leading competitors.
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.
Recently, they have been under serious attack with major exploits, such as Log4j, affecting Fortinet and Palo Alto, and even Cisco and VMware.
AI-based recommendations save on time and money.
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
7.1
Microsoft support is generally satisfactory, with users preferring higher-tier options for faster response and clearer communication.
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.
They are good at troubleshooting and configuring things.
I am very satisfied with the response from Microsoft dedicated architects if it happens that I have to call for their support.
I reached out to their support, and they helped me resolve the issue effectively.
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
6.6
Azure Web Application Firewall offers flexible, highly-rated scalability, easily adapting to traffic changes and various workload needs across subscriptions.
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.
Some Azure applications, like the web application firewall, require a certain level of SKU for hosting setup.
For our company, Azure Web Application Firewall works effectively for scalability.
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
7.1
Azure Web Application Firewall is highly stable, with minimal connectivity or performance issues and consistently earns high reliability ratings.
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.
Very rarely do I see any latency issues.
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.
Azure Web Application Firewall needs better reporting, integration, cost plans, and process streamlining for enhanced management and 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.
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.
Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead.
The pricing needs improvement, and I think for beginners it will be a little bit complicated, so the ease of use could be enhanced.
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.
Azure Web Application Firewall offers scalable pricing, valued functionality, and favorable terms, appealing compared to AWS and GCP.
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.
It is even a lower cost compared to AWS and GCP.
Sometimes, when opting for a higher SKU, it's not the WAF itself that's costly but the additional requirements.
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.
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.
Azure Web Application Firewall offers robust security, seamless Azure integration, automatic rule management, and scalable, user-friendly deployment with minimal downtime.
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.
With Microsoft, everything is within a single suite, making it easier to configure and plan.
It is almost impossible to access these assets from outside, requiring a very skilled attacker to obtain asset tokens of a customer using Azure.
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.
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.

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.
Mano Senaratne - PeerSpot reviewer
Comprehensive suite simplifies configuration while frequent updates require management
Mainly, it comes with the complete suite of Microsoft services. I can use it in conjunction with the best options and other features that come with it. Configuration is much easier than using different platforms. For example, if I have hosted the application in AWS and am using the Application Firewall from Azure, there are certain additional steps to follow when configuring them. With Microsoft, everything is within a single suite, making it easier to configure and plan. Azure continually upgrades platforms and sends us messages to upgrade to the next version, simplifying the process. Later, it's much easier if I want to upgrade the software platform, scale it, or move it to a different application host as the whole suite comes together. The return on investment is good. If I am doing applications for clients, I can invoice them for better costs. Most applications that I run and use have a better return on investment.
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.
