BENEFITS OF CLOUDFLARE SPECTRUM
Block volumetric DDoS attacks

With a network mitigation capacity of 280 Tbps, Spectrum mitigates even the largest DDoS attacks — before they reach your server.

Accelerate network traffic in real time

Spectrum integrates with Argo Smart Routing to send TCP traffic faster than the ‘best-effort’ Internet.

Increase uptime with faster failovers

With Load Balancing, all active TCP connections and UDP traffic automatically failover to a healthy server, helping increase the uptime of your services.

HOW IT WORKS

Secure and accelerate your TCP and UDP applications

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.
