    Web Application Firewall:Billing overview

    Last Updated:Mar 20, 2024

    Web Application Firewall (WAF) 3.0 supports the subscription and pay-as-you-go billing methods. The subscription billing method is more suitable for budget-conscious customers, customers whose resource usage remains relatively flat, and customers who require resources for long-term use. The pay-as-you-go billing method is more suitable for customers who require resources for short-term use. This topic describes the scenarios, billable items, billing cycles, and activation methods of subscription and pay-as-you-go WAF instances.

    Note

    WAF 3.0 instances do not support switching between different billing methods.

    Billable items

    • Features: You are charged for the features of your WAF instance based on the edition, specifications, and subscription duration. Basic Edition, Pro Edition, Enterprise Edition, and Ultimate Edition support the subscription billing method.

    • Value-added features: You are charged for the value-added features based on the specifications and subscription duration.

    • Request processing: You are charged for request processing. The fees include basic request fees and bot management fees.

    • Features: You are charged for features based on the actual usage of features. Security capacity units (SeCUs) are used to calculate the bills.

    Billing cycle

    The billing cycle of a subscription WAF instance is the subscription duration of the WAF instance, which is the subscription duration that you specify when you purchase the WAF instance.

    The fees of a pay-as-you-go WAF instance are generated on a daily basis (UTC+8). After fees are calculated, a new billing cycle begins.
