A10 Networks Thunder ADC and Kemp LoadMaster both compete in the application delivery controller category. A10 Networks Thunder ADC appears to have an upper hand due to its comprehensive feature set and cost-effectiveness.
Features: A10 Networks Thunder ADC is noted for its all-inclusive licensing model which simplifies budget management, advanced DDoS mitigation, and SSL offloading. These features make it ideal for enterprises handling mixed traffic across on-premise and cloud resources. Kemp LoadMaster is recognized for ease of deployment, stability, and a competitive cost-to-feature ratio, making it suitable for straightforward ADC needs lacking advanced security measures.
Room for Improvement: A10 Networks Thunder ADC could improve its third-party integration options and address regional support discrepancies causing delays. Resolving legal issues with Brocade and enhancing immediacy in support could also benefit users. Kemp LoadMaster might enhance security features and GUI usability, and integrate modern visualization tools and better certificate management. Users suggest more comprehensive documentation and intuitive updates for advanced configurations.
Ease of Deployment and Customer Service: A10 Networks Thunder ADC is often deployed on-premises, but users report delays in support during emergencies, and highlight a need for improved first-call resolutions and better training resources. Kemp LoadMaster is praised for its straightforward setup and reliable third-party support across varied deployments, with customer service improving satisfaction despite a call for more proactive support.
Pricing and ROI: A10 Networks Thunder ADC is perceived as cost-effective, offering a solid return on investment by simplifying configuration and saving on support contracts. It competes well with more expensive solutions like F5. Kemp LoadMaster's competitive pricing and trial options make it attractive for clients seeking cost-effective ADC solutions, with licensing flexibility enhancing its appeal against pricier alternatives.
We do see a return on investment and cost reductions after the implementation of A10 Networks Thunder ADC.
Their tech support is very responsible, and their response time is very low, providing superb support.
The support we receive from the team is quite excellent.
We have not received technical support from Kemp LoadMaster without a license.
A10 Networks Thunder ADC can handle growth easily, and I have scaled up during higher traffic periods.
A10 Networks Thunder ADC's scalability is impressive.
Kemp LoadMaster is a scalable solution.
In some of our deployments of A10 Networks Thunder ADC, we have employed DDoS and other security features, and for the past few years, we haven't experienced any major incidents.
Most of the time, it just runs in the background without issues.
With the license purchase afterwards, if it expires, it begins dropping the HTTP traffic, also the DNS traffic.
Having more structured, real-world configuration examples would make a big difference, especially for teams that are new to the platform, helping reduce the initial learning curve for them.
In the vThunder series of A10 Networks Thunder ADC, they have a perpetual license model and a subscription model, but in the Thunder series, the physical appliance does not have a perpetual license model, mainly operating on the subscription model.
Enhanced integration with third-party tools would be beneficial.
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.
I estimate that I can save around 20 to 30 percent of my budget with A10 Networks Thunder ADC.
Application load balancing in A10 Networks Thunder ADC plays a crucial role in improving application reliability during peak periods.
What really stands out to me about A10 Networks Thunder ADC is how customizable, performant, and automated the platform is.
I would assess A10 Networks Thunder ADC's load balancing for improving application reliability during peak periods at around 9 out of 10, as GSLB is far better, and we are very satisfied with it.
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.
