Interfaces for login, transaction, and query are overwhelmed by a large number of forged requests, causing processing performance to be exhausted.

E-commerce, finance, and social entertainment
For L7 DDoS (CC) attacks, DDoS Defender provides protection capacity support and combines with EdgeOne (EO) policy configuration capabilities to deliver complete protection.

Short-term high-risk windows such as pre-sale warm-ups, version releases, and live broadcasts of major events
E-commerce, gaming, and video
Supports upgrading the plan tier or purchasing additional Protection Capacity Add-ons on demand. After the event ends, you can downgrade the plan as needed. For details, see Purchase Guide and Plan Upgrade and Downgrade Guide.
