Spectrum works as a layer 4 reverse proxy, extending Cloudflare DDoS protection and traffic acceleration to any box, container, or virtual machine (VM) connected to the Internet.

And with our built-in, software-defined IP firewall, you can easily control the flow of traffic to your application servers — no hardware or costly maintenance required.
