Buying a Cloud WAF InstanceBuying a WAF Instance

Cloud WAF instances are billed either on a yearly/monthly (prepaid) or pay-per-use (postpaid) basis. In the yearly/monthly billing mode, the standard, professional, and platinum editions are available. Each edition offers domain, QPS, and rule expansion packages.

  • Only one WAF edition can be purchased under an account in the same geographic region.
  • The specifications of a WAF instance cannot be changed once you complete the purchase. To use a WAF instance with lower specifications, unsubscribe from the WAF instance you are using and buy another one.
  • Expansion package can only be renewed or unsubscribed together with the WAF instance you are using.

Specification Limitations

  • A domain package allows you to add 10 domain names to WAF, including one top-level domain and nine subdomains or wildcard domains related to the top-level domain.

      QPS: 1,000 (Each HTTP GET request is a query.)

  • A rule expansion package allows you to configure up to 10 IP address blacklist and whitelist rules.

Application Scenarios

The application scenarios for different editions are as follows:

  • Standard edition

    This edition is suitable for small- and medium-sized websites that do not have special security requirements.

  • Professional

    This edition is suitable for medium-sized enterprise websites or services that are open to the Internet, focus on data security, and have high security requirements.

  • Platinum

    This edition is suitable for large- and medium-sized enterprise websites that have large-scale services or have special security requirements.
