Find out in this report how the two Web Application Firewall (WAF) solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI.
Reducing infrastructure costs by 40 to 60% because Edge Caching minimizes backend traffic, resulting in lower computing costs.
I have seen a return on investment, particularly in time savings, especially regarding the changes.
demonstrating the team's technical expertise in CDN and Edge architecture
We are not getting quick responses from Fastly technical support engineers.
I would describe Fastly's customer support as fast and efficient when I have had to use it.
We have not received technical support from Kemp LoadMaster without a license.
Seamlessly handling massive traffic without requiring backend changes due to its globally distributed Edge network and stateless API-driven design.
Kemp LoadMaster is a scalable solution.
Highly reliable for enterprise-scale applications with high uptime guarantees.
With the license purchase afterwards, if it expires, it begins dropping the HTTP traffic, also the DNS traffic.
I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities.
Fastly could improve by improving the documentation and having some code examples.
Fastly should provide features similar to Cloudflare regarding a block list.
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.
It operates on a pay-as-you-go structure, but costs scale with traffic, requiring monitoring to avoid unexpected spikes based on data transfers and the number of requests handled.
In terms of price, I find it good.
We observed a 30 to 50% reduction in response time and a significant reduction in backend load of 40 to 60%, improving visibility through a real-time dashboard for monitoring traffic, errors, and performance.
We have improvements in traceability by having the changes integrated into the Git repositories and having the possibility of doing a rollback in the event of any problem in a very simple way.
In this project, it is working as a reverse proxy for CDN and WAF, web application firewall, additionally image optimization.
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.
