Radware Alteon and Kemp LoadMaster are prominent competitors in the application delivery controller market. Radware Alteon has the upper hand in comprehensive application delivery and integrated security features, while Kemp LoadMaster is favored for its cost-effectiveness and ease of deployment.
Features: Radware Alteon offers advanced application delivery, SSL offloading, and integrated application protection with robust hardware. Its security capabilities include DDoS protection and WAF, appreciated for flexibility and scalability. Kemp LoadMaster provides a high price-performance ratio, ease of deployment, and intuitive templates for common applications. Its high-availability features and automated WAF updates boost security with minimal complexity.
Room for Improvement: Radware Alteon users suggest improvements in automation, interface intuitiveness, and third-party tool integration, with reported issues of false positives and complex configurations. Kemp LoadMaster could enhance its UI polish and real-time traffic visibility. Advanced analytics, security features, and training resources are areas for potential enhancement.
Ease of Deployment and Customer Service: Radware Alteon is stable across on-premises, public cloud, and hybrid set-ups, though some find the setup intricate and support inconsistent outside peak hours. Kemp LoadMaster is praised for deployment simplicity in similar environments, with high customer support satisfaction due to quick and efficient responses.
Pricing and ROI: Radware Alteon is a mid-range solution offering a good return on investment with its robust features, though priced higher than some competitors. It yields time savings and operational efficiencies. Kemp LoadMaster is highly cost-effective, offering competitive pricing and ROI, with flexible licensing and strong performance for its cost in price-sensitive settings.
We have not received technical support from Kemp LoadMaster without a license.
We never face support issues, and their team resolves any critical issues quickly once they are involved.
There is a dedicated expert answering even the toughest questions.
The customer service and support are excellent.
Kemp LoadMaster is a scalable solution.
It handles peak loads and thousands of concurrent connections without exceeding 10% utilization.
We have it deployed across multiple geographic locations, benefiting from load balancing resiliency.
Within a couple of hours, if the deployment is very straightforward and if the requirements or the IP addresses are already in place, the deployment can be completed.
With the license purchase afterwards, if it expires, it begins dropping the HTTP traffic, also the DNS traffic.
We've never faced downtime, even during peak transaction hours.
There is minimal downtime, and the solution is quite stable.
There are no difficulties with the deployment of Radware Alteon; it is quite straightforward.
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.
In the future, I would like to see some other security features added, such as DDoS, which is Distributed Denial of Service.
Other OEMs offer free courses and hands-on labs on new technologies and features, which we find useful.
They keep integrating new features that sometimes break our production, but we use clustered systems, so we can test those software releases.
For our solution, it was right in the middle of price performance.
The implementation and running costs are quite high.
The cost of the Radware solution is reasonable and stable.
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.
The product allows us to manage multiple networks and VLANs into a single box and add numerous web services and farms efficiently.
The best feature of Radware Alteon is basically the configuration; how we configure it is very straightforward, and it is very simple to configure.
The most valuable features include the availability with an optional high-availability mode ensuring service continuity because of the resiliency.

Kemp LoadMaster enhances server performance by providing secure, intuitive load balancing solutions with easy deployment. It supports high availability, integrates seamlessly with IT infrastructure, and ensures optimal traffic distribution for critical applications.
Kemp LoadMaster is known for its ease of use and high-level security capabilities, making it ideal for managing multiple servers. Its intuitive interface simplifies configuration for load balancing and reverse proxy across multi-site Exchange, while the Edge Security Pack distinguishes between critical infrastructure and public internet. Supporting seamless service continuity and effective traffic distribution, it significantly boosts server performance through SSL offloading and intelligent monitoring. However, improvements are desired in stability and reporting, as well as in security features such as a robust Web Application Firewall and more intuitive logging and monitoring.
What are Kemp LoadMaster's Key Features?Kemp LoadMaster is implemented across industries that require robust IT infrastructure management. Organizations use it for load balancing in Exchange environments, securing web servers, and maintaining high availability for public sector services. It supports applications like RDP, SQL, DNS, SharePoint, Citrix, and VoIP, ensuring security and high performance.
Alteon is Radware’s application delivery and security platform for delivering and protecting applications across physical, virtual, cloud, and hybrid environments. Available as hardware, virtual appliances cloud deployment, Alteon provides local, global server and link load balancing, advanced traffic management, SSL/TLS offload and acceleration, automation, and application optimization, including HTTP/2 and HTTP/3 support.
Through Alteon Protect, organizations can combine Alteon application delivery and on-device security with Radware Cloud Application Protection services, including web application and API protection, bot management, and web DDoS protection. This provides a unified application delivery and security approach across data center and cloud environments.
Alteon supports flexible capacity and deployment through Global Elastic Licensing (GEL), which enables licensed capacity to be allocated and reallocated across supported Alteon deployments as application and infrastructure requirements change.
The platform also supports modern automation and AI-assisted operations. Alteon MCP Server enables application, DevOps, and platform teams to use natural-language intent through an MCP-compatible AI client to create supported Alteon configurations using a guided workflow that gathers required parameters, validates configuration state, and maintains human review and approval before changes are applied. Alteon also supports lifecycle automation and integration through REST APIs, Ansible, Terraform, and Kubernetes/cloud-native environments.
Together, these capabilities enable organizations to deliver, scale, automate, and protect applications consistently across data centers, private clouds, public clouds, and hybrid environments.
Alteon supports flexible perpetual and subscription-based licensing models. Physical appliance pricing is based on the selected Alteon hardware platform and enabled performance/capacity, while virtual and cloud deployments can be licensed according to the required capacity as a subscription. Global Elastic Licensing (GEL) provides additional flexibility by allowing licensed capacity to be allocated and redistributed across supported Alteon physical, virtual, and cloud deployments rather than tying all capacity permanently to an individual instance.
Customers can also purchase application delivery together with cloud-delivered application protection through Alteon Protect, providing a combined subscription model for Alteon application delivery and Radware Cloud Application Protection capabilities.
