A data-driven look at the evolving DDoS threat landscape, the industries bearing the brunt of modern attacks, and why the architecture that protected your network five years ago can no longer keep up.
12 months of Cloudflare Radar data on the rise in frequency, volume, and sophistication of enterprise network attacks.
Weekly L3/L4 DDoS attack volume index — normalized to the annual peak. The last 8 weeks of data represent a sustained surge, not a temporary spike. March 2026 hit record levels.
For as little as $10/hour, anyone can rent a botnet capable of generating hundreds of Gbps of traffic. The barrier to entry for launching a devastating attack has effectively reached zero.
Modern botnets span millions of compromised IoT devices, cloud instances, and servers across 160+ countries. Geographic distribution makes traditional IP-based blocking ineffective.
Attackers now launch simultaneous L3, L4, and L7 attacks — volumetric floods combined with protocol exploits and application-layer probing. Single-layer defenses are trivially bypassed.
The average enterprise firewall handles ~25 Gbps. The largest attacks Cloudflare sees today exceed 7,300 Gbps. That is a 292× gap. No amount of hardware investment closes it.
12 months of Cloudflare Radar data on the industries and geographies bearing the heaviest DDoS attack load.
By attack byte volume over the past 12 months (Apr 2025–Mar 2026). Two sectors dominate — but every industry in this room has skin in the game.
Carriers own massive IP blocks and act as both targets and unwilling attack infrastructure. Their networks are simultaneously victimized and weaponized.
Gambling, Gaming, and real-time platforms are targeted because every minute of downtime is immediately measurable in lost revenue. Attackers know exactly what the pain is worth.
China, the US, and Hong Kong collectively absorbed 85% of all L3/L4 DDoS attack bytes over the past 12 months — but every global enterprise with IP infrastructure is exposed.
If your organization has infrastructure in APAC, the Americas, or Europe — you are in a high-risk geography. Distributing your infrastructure does not distribute your risk. It multiplies your attack surface.
On-premise hardware was built for a threat landscape that no longer exists. Here is exactly why — and what you need instead.
Your appliance sits downstream of your ISP link. A volumetric attack saturates that link first. Your hardware never fires a packet. The network is offline before the defense activates.
Top enterprise appliance: ~25 Gbps. Largest observed attack: 7,300 Gbps. To match that with hardware you need 292 appliances — at every location you operate. The math doesn't work.
Threat intelligence updates require manual patching. Hardware refreshes happen every 3–5 years. Every upgrade window is a window of exposure. The threat actors don't take a maintenance window.
Magic Transit moves the defensive perimeter from your data center to Cloudflare's global edge — 405+ Tbps of scrubbing capacity across 330+ cities. Attacks are absorbed upstream of your ISP link. Clean traffic reaches you. Always on. Zero hardware. Predictable OpEx.
| Capability | Hardware Appliance | Magic Transit |
|---|---|---|
| Max DDoS Capacity | ~25 Gbps | 405+ Tbps |
| Upstream of ISP Link | ✗ No | ✓ Yes — global edge |
| Protection Activation | Manual | Always-on, automatic |
| Detection Speed | Minutes | <3 seconds |
| Threat Intelligence | Manual patching | Real-time, automatic |
| High Availability | Buy 2× hardware | Built-in anycast |
| Latency Impact | Negative (bottleneck) | None to negative |
| Firewall / IDS | Separate appliance | Magic Firewall built-in |
| Zero Trust Integration | ✗ Separate stack | ✓ Native CF One |
| Cost Model | High CapEx + OpEx | Predictable OpEx |
| Refresh Cycle | Every 3–5 years | Never — cloud-native |
1. Attack volumes are at record highs and accelerating. Q1 2026 produced the highest attack week of the past 12 months. This is not a temporary spike — it is the new baseline.
2. Your industry is in the bullseye. IT, Telecom, Gambling, Gaming, and Financial Services together absorbed 89% of all attack volume over the past year.
3. The architecture has to change. Hardware appliances were designed for a threat landscape that no longer exists. The ISP choke point problem alone makes on-premise defense structurally insufficient at modern attack scales.
405+ Tbps of always-on DDoS protection, upstream of your ISP link, across 330+ cities — with Magic Firewall deep packet filtering and IDS built in. No hardware to buy, patch, or refresh. One subscription. Your entire network, protected at Cloudflare scale.
We'll show you exactly what Cloudflare can see about your network's attack surface, IP space, and ASN exposure — right now, before you buy anything.
We can have clean traffic flowing to your data center quickly, in parallel with your existing infrastructure — no forklift migration required.
