To initiate an exception request to enable this integration for your organization, email [support@ddog-gov.com](mailto:support@ddog-gov.com). {% /alert %} {% /callout %} ## Overview{% #overview %} Alibaba Cloud Web Application Firewall (WAF) protects web applications from common attacks such as SQL injection and cross-site scripting (XSS). It also guards against malicious bots, Challenge Collapsar (CC) attacks, and unwanted traffic. Use this integration to monitor WAF request rates, block rates, and resource usage across your protected domains. ## Setup{% #setup %} ### Installation{% #installation %} After you set up the [Alibaba Cloud](https://docs.datadoghq.com/integrations/alibaba_cloud.md) integration, ensure that the WAF service is included in your Alibaba Cloud monitoring configuration. ##
