Magic Transit – an effective shield against DDoS in an era of growing threats

Today’s attacks:

• are increasingly large (often exceeding the victim’s bandwidth capacity),
• utilize IoT botnets comprising millions of devices,
• are automated and conducted in waves or continuously,
• target entire networks and infrastructure layers, not just single applications.

This means that local filtering systems or firewalls cannot cope with such a scale. Protection needs to be planned at the infrastructure design stage – and based on solutions capable of absorbing even the largest volumetric attacks.

Magic Transit is an advanced network service from Cloudflare that takes DDoS protection to the operator’s infrastructure level – before any malicious packet reaches the client’s network. All traffic is directed through the global Cloudflare Anycast network with over 300 data exchange points, where it is analyzed, filtered, and delivered to the client only as safe, cleaned traffic.

What does Magic Transit from Cloudflare provide?

• DDoS protection at the L3/L4 level – protects entire IP subnets, not just applications.
• Global traffic filtering – traffic is intercepted closest to the attack source.
• Constant analysis and anomaly detection thanks to machine learning and real-time monitoring.
• Automatic response without delays – no need for manual mitigation switching.
• Full integration with the client’s existing infrastructure (GRE tunnels, BYOIP, integration with operators).

This approach significantly reduces the risk of bandwidth overloading and eliminates the attack before it reaches the corporate network.

1. Machine learning and analysis of global traffic patterns

In an era of botnets generating billions of requests per second, the ability to distinguish them from real user traffic becomes key. Cloudflare, thanks to its distributed system for observing traffic from hundreds of data centers, can:

• recognize irregular traffic patterns,
• detect anomalies in milliseconds,
• block attacks before they reach applications or servers.

2. Cloudflare services for applications

Cloudflare not only protects networks but also individual applications. Complementing Magic Transit are, among others:

• Cloudflare WAF – protection against application layer attacks,
• Bot Management – differentiates between user and bot traffic,
• CDN and cache – relieve servers and improve performance,
• Cloudflare Zero Trust – access control and enhanced employee security.

3. Cloudflare network services – the foundation of security and performance

Cloudflare provides a complete set of network tools, eliminating the need for costly, physical devices:

• Magic WAN – a modern alternative to MPLS,
• FWaaS – Firewall as a Service,
• Cloudflare Network Interconnect – secure, private connections to the global Cloudflare network.

The combination of Magic Transit with network services creates a complete protection strategy – against both volumetric attacks and application threats.

The scale and complexity of DDoS attacks increase annually. Point protection is no longer effective – a solution that encompasses the entire network infrastructure, real-time monitoring, and a global operating scale is required.

Cloudflare Magic Transit is a solution designed precisely with these challenges in mind. By combining massive mitigation power, intelligent analysis, and Cloudflare’s network and application services, organizations gain comprehensive DDoS protection – from the network layer to the applications themselves.
