Note:
The following policies apply to EO DDoS Defender subscriptions beginning January 13, 2026.
After connecting your business to EdgeOne, you'll automatically receive standard DDoS protection, sufficient for most websites and TCP/UDP applications. For businesses at higher risk of DDoS attacks or requiring custom protection rules configuration, EdgeOne DDoS protection product offers a DDoS Defender plan.

Note:
Note 1: Attack traffic dropped by DDoS scrubbing is not billed. See the Billing Notes for "Clean Traffic" for details. Clean traffic after protection is billed per the DDoS Defender pricing guide.
Note 2: By default, automatic scrubbing is triggered only when attack traffic exceeds 100 Mbps (measured per service node region; threshold is for reference—actual mitigation behavior prevails).
Note 3: Actual protection capacity is dynamically adjusted based on infrastructure availability. When an attack exceeds current capacity, EdgeOne may take additional measures—including traffic scheduling, traffic throttling, or null-routing—to safeguard platform stability.

Note 4
: The protection region for DDoS Defender aligns with the acceleration region of the EO site or layer-4 proxy instance.

Note 5:
"No capacity commitment" means EO will protect your business with limited resources to maintain infrastructure stability, without promising minimum protection bandwidth.

Note 6:
"Unlimited Anycast protection" means EO uses Anycast architecture in global regions (excluding mainland China) to defend against DDoS attacks. The protection capacity can exceed 10 Tbps. For the latest bandwidth capacity, see the product intro page.
