DDoS Defender (Anti-DDoS)
DDoS Defender delivers automated attack mitigation and traffic cleansing for cloud and internet-facing workloads, with protection capacity of up to Tbps scale. Attack traffic is automatically mitigated, and mitigated attack traffic is not billed. With DDoS Defender, you can keep your business online during large-scale attacks and reduce security build-out and operations costs.









A DDoS Defender protection can be associated with resources such as CVM, CLB, EIP, WAF, LH, and EdgeOne (domains, L4 proxy instances, and BGP transit CIDRs). Protection instances are not bound to a region and can be associated across regions. Workloads outside Tencent Cloud or in self-built IDCs can be protected through EdgeOne proxy or BGP transit origin forwarding.
Mitigated attack traffic incurs no charges. Clean data transfer fees are calculated only on clean business traffic after mitigation. Up to 10 TB per month is included in the plan, and usage beyond that is billed with pay-as-you-go method.
