NetScaler and HAProxy are both high-performance load balancers in the application delivery category. NetScaler appears to have the upper hand for enterprises needing advanced features and extensive support.
Features: NetScaler is favored for strong security and integration options, including SSL offload and comprehensive management capabilities, which benefit enterprises in complex environments. It excels with its flexible deployment model and advanced settings, allowing extensive traffic management and application delivery solutions. HAProxy is praised for reliability and low-level control, offering versatile load-balancing algorithms and customization due to its open-source nature.
Room for Improvement: NetScaler users note the need for upgrading the user interface and simplifying configurations, as well as addressing issues with frequent updates and inconsistent support. HAProxy could enhance GUI features and allow dynamic configurations without service interruption, in addition to improving documentation and monitoring tools.
Ease of Deployment and Customer Service: NetScaler is versatile with deployment options ranging from on-premises to hybrid cloud environments and offers robust technical support with varying feedback on effectiveness. HAProxy, being open-source, is easy to deploy in on-premises setups with simpler licensing, but customer service is less extensive compared to paid enterprise options like NetScaler.
Pricing and ROI: NetScaler is expensive with significant upfront costs due to licensing, making it a premium solution for larger enterprises seeking advanced functionalities. It offers positive ROI through stability and comprehensive management. HAProxy appeals to cost-conscious businesses with no license fees and low TCO, offering excellent value for money. Although its basic version is free, enterprises might opt for paid versions for enhanced support.
HAProxy is considered by many in the industry to be one of the fastest and most popular and trusted software load balancer products in the marketplace today. Organizations are able to immediately deploy HAProxy solutions to enable websites and applications to optimize performance, security, and observability. HAProxy solutions are available to scale to any environment.
HAProxy is an open-source product and has a robust, active, reliable community. The solutions are continually tested and improved on by the community. HAProxy offers a dynamic design to support the most modern architectures, microservices, and deployment environments (appliances, containers, virtual, and cloud).
HAProxy utilizes a cloud-native protocol, which makes it a complete solution for cloud services such as Red Hat OpenShift, OVH, Rackspace, Digital Ocean, Amazon Web Services (AWS), and more. It also can be used as the reference load balancer in OpenStack.

Reviews from Real Users
“Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind.” - Nathanel S., Platform Architect at SES
“I use HAProxy for individuals who can not buy low balancers. I built NFV in a box and send individuals a pathway into an HAProxy VM. The setup was not difficult; it usually takes a day to complete for a VPC. When it comes to pricing, HAProxy is free.” - Nasir O., Network & Cloud Architect at Koala Compute Inc.
One platform for a consistent application delivery and security experience because nobody has time to learn multiple systems to manage ADC deployments. NetScaler is built with a single code base using a software-based architecture, so no matter which ADC form factor you choose — hardware, virtual machine, bare metal, or container — the behavior will be the same.
