Does WAF Have a Limit on the Protection Bandwidth or Shared Bandwidth?

WAF does not limit the protection bandwidth or shared bandwidth. WAF limits the service bandwidth and QPS.

The service QPS in WAF refers to the amount of normal traffic (unit: QPS) over all domain names and websites a WAF instance can protect.

Before buying WAF, confirm the total inbound and outbound peak traffic of the websites to be protected by WAF. Ensure that the bandwidth of the WAF edition you select is greater than the total inbound peak traffic or the total outbound peak traffic, whichever is larger.
