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
7.9
HAProxy offers cost-effective traffic management, enhanced efficiency, and high ROI through streamlined processes and reduced manual intervention.
Sentiment score
7.4
Kemp LoadMaster is a cost-effective solution that enhances efficiency, security, and offers significant returns quickly in various industries.
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 quick, but technical support feedback is mixed, with improvement needed in responsiveness and detailed assistance.
Sentiment score
6.9
HAProxy's customer service is swift and effective, but open-source support lacks the comprehensiveness of enterprise alternatives.
Sentiment score
8.8
Kemp LoadMaster support is highly rated for its knowledgeable, efficient team offering quick issue resolution and comprehensive online resources.
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.
We have not received technical support from Kemp LoadMaster without a license.
 

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
7.8
HAProxy is praised for its scalability, efficiency, and flexibility, handling thousands of connections and supporting mid-sized deployments seamlessly.
Sentiment score
8.2
Kemp LoadMaster is highly scalable, supporting smooth upgrades and adaptable licensing for both small and large enterprises.
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.
Kemp LoadMaster is a scalable solution.
 

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
HAProxy is highly stable, reliably managing heavy traffic with minimal downtime, efficient support, and consistent functionality improvements.
Sentiment score
8.7
Kemp LoadMaster is praised for its stability, reliability, high availability, and effective server load management with minimal downtime.
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.
With the license purchase afterwards, if it expires, it begins dropping the HTTP traffic, also the DNS traffic.
 

Room For Improvement

Enhancements needed in Cloudflare: analytics, CDN latency, API integration, user support, DNS, pricing, documentation, server coverage, WAF, and cache.
HAProxy needs better GUI, dynamic configuration, user-friendly logging, REST API, cloud integration, security, and community features.
Kemp LoadMaster needs UI, security, documentation enhancements, improved monitoring, automation, analytics, and better cloud integration.
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.
After that, they said if it was good, we could purchase the license, and while we found it very good, the license cost was too high.
 

Setup Cost

Cloudflare offers scalable pricing, from free to enterprise plans, providing significant value especially for mid-sized companies.
HAProxy is cost-effective, praised for simple licensing, robust features, and valued by enterprises despite requiring expertise for setup.
Kemp LoadMaster offers flexible, cost-effective licensing and setup with positive user feedback and a 30-day free trial.
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 performance and security with CDN caching, DDoS protection, and an easy-to-use dashboard, benefiting many users.
HAProxy is praised for its excellent load balancing, reliability, customization, scalability, advanced traffic rules, and open-source integration.
Kemp LoadMaster offers ease of use, security features, Azure integration, and cost-effective load balancing for Microsoft applications.
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.
We had some issues in patching management, so we deployed this product for virtual patching, the IPS rule, and it gives us very good results because we have very critical servers.

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.
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.
IshtiaqKhalil - PeerSpot reviewer
Displays flexible, user-friendly interface with minor licensing challenges
The product could be improved with a more intuitive interface for complex configurations and more advanced analytics. Additionally, enhanced security features, like a more robust Web Application Firewall, and stronger APIs for better automation would be beneficial. Overall, the main areas for improvement are in strengthening the advanced features to better meet the demands of large-scale enterprise environments. key features for the next release should focus on three areas. First, an enhanced, next-generation security suite with a more powerful Web Application Firewall (WAF) and integrated bot protection. Second, more advanced and customizable analytics dashboards to provide deeper insights into application performance. Finally, greater support for modern, cloud-native environments, including better APIs for automation and seamless hybrid-cloud traffic management
