Web Application Firewall (WAF) supports the subscription billing method.


Billing item: You are billed based on the subscription plan.

Payment method: You must pay before you use the service.

Billing period: The service is billed monthly or annually based on your order. A bill is generated each time you place an order.

Fee deduction day: The fee deduction day is calculated based on the service duration. You can set the service duration to one month, three months, half a year, and one year.

Expiration: The protection stops automatically when the service expires.
  • You will be notified by email or SMS seven days before expiration. If you do not renew the service before the service expires, WAF stops providing protection after the expiration date.
  • After the service expires, WAF retains your configuration for seven days. If you renew the service within seven days, WAF continues to protect your domains based on the existing configuration. Otherwise, your configuration is released, and you must configure the WAF instance again.


WAF does not support unconditional refunds or partial refunds.
