Cloudflare Spectrum

The Internet is more than the web. It comprises many other TCP/ UDP applications that have the same fundamental needs as web services – speed, security, and reliability.

Cloudflare Spectrum is a reverse proxy product that extends the benefits of Cloudflare to all TCP/UDP applications.

Better apps, lower cost.

It’s best-in-class networking, without the hardware. WAN acceleration, DDoS mitigation, and load balancing appliances need racking, stacking, and cabling that also involve high CAPEX costs. With Spectrum, pay for only what you use — without the hardware maintenance costs.

Real-time traffic acceleration

Speed is an integral part of many applications. Often, applications such as RDP, VoIP, RTMP or custom financial and gaming applications require low end-to-end network latency to deliver consistent, reliable, and ‘real-time’ experiences to end-users.

Cloudflare Spectrum integrates with Argo Smart Routing to send TCP traffic faster than the ‘best-effort’ Internet. Cloudflare’s network learns from the traffic of millions of Internet properties, enabling machine-learning (ML) based intelligent routing around network congestion in real-time.

Based on synthetic measurement tests between Western America and Singapore, we saw a nearly 17% decrease in the TCP roundtrip time (RTT) on Cloudflare's network when compared to sending the traffic directly on the Internet.

Best-in-class DDoS protection

With a network mitigation capacity of over 142 Tbps, instant threat detection, a time to mitigate (TTM) under 3 seconds for most threats, Spectrum proxies and protects your applications against the most sophisticated and multi-vector DDoS attacks. With a network of data centers that spans over 270 cities in 100 countries, Spectrum is well-positioned to stop DDoS attacks in the cloud closest to the attack source, well before they reach your application server.

IP Firewall included

IP Firewall

Spectrum comes with a completely software-defined IP firewall that can be configured right from the dashboard or API. You can allow or deny individual IPs or IP ranges to granularly control traffic to your application server. You can also configure rules to block visitors from a specified country or even an Autonomous System Number (ASN).

Increased reliability with faster failovers

In the event of a downtime, all active TCP connections and UDP traffic automatically failover to an alternate healthy server in a configured load balancing pool to prevent downtime. By dynamically distributing it to the most available and responsive server pools, Cloudflare Spectrum and Load Balancing together help increase the uptime of your services.
