Cloudflare Magic Transit

Cloudflare Magic Transit is a high-performance network security and acceleration solution designed to protect on-premises data centers, private cloud environments, and hybrid networks from distributed denial-of-service attacks while optimizing internet traffic routing. Utilizing Border Gateway Protocol (BGP) route announcements and Anycast architecture, Magic Transit announces customer IP prefixes across Cloudflare global network spanning more than 330 cities, absorbing and scrubbing malicious traffic at the edge before forwarding clean packets to customer origins via encrypted GRE or IPsec tunnels.

By inspecting and filtering inbound traffic across Cloudflare entire 300+ Terabits per second network backbone, Magic Transit effortlessly mitigates massive multi-gigabit volumetric DDoS floods, SYN floods, UDP amplification attacks, and protocol anomalies with sub-second response times. Unlike traditional scrubbing center architectures that introduce significant latency by backhauling traffic through distant scrubbing hubs, Magic Transit cleans traffic locally at the closest edge server to the source, often accelerating legitimate user traffic via Cloudflare optimized global routing. Furthermore, Magic Transit integrates seamlessly with Cloudflare Magic Firewall, allowing organizations to enforce granular packet filtering rules directly at the edge.

Magic Transit integrates with enterprise network infrastructure, Cisco, Juniper, and Arista edge routers, and SIEM observability platforms like Splunk, Datadog, and Catchpoint. Common enterprise use cases include protecting critical banking and financial transaction backbones, shielding gaming servers from disruption, ensuring internet connectivity for government agencies, and eliminating expensive on-premises DDoS appliances. Cloudflare Magic Transit delivers unmatched network resilience, ultra-low latency, and carrier-grade availability.
