Public Preview: JavaScript (JS) Challenge on Azure WAF integrated with Azure Application Gateway

Azure Web Application Firewall (WAF) integrated with Azure Application Gateway now supports JavaScript (JS) challenge. Azure WAF JS challenge is available as a new mitigation action as part of the Bot Manager rule set and custom rules.

The JavaScript challenge is an invisible web challenge used to distinguish between legitimate users and bots. Malicious bots fail the challenge, which protects web applications. In addition, the JavaScript challenge is beneficial as it reduces friction for legitimate users since it does not require human intervention.
