Generally Available: Azure WAF JavaScript challenge on Azure Front Door

Announcing the general availability of JavaScript (JS) challenge for Azure Web Application Firewall (WAF) with Azure Front Door 

To strengthen bot mitigation strategies, Azure WAF now introduces JS challenge as a new security feature. The JS challenge provides an invisible, frictionless layer of protection by distinguishing legitimate users from malicious bots without requiring human interaction. Unlike CAPTCHA, this challenge runs silently in the background, reducing user disruption while effectively blocking harmful automated traffic. 

Key benefits include: 

• Enhanced bot protection: Malicious bots fail the JS challenge, safeguarding your applications. 
• Improved user experience: Legitimate users are not interrupted, ensuring seamless access. 
• Flexible integration: Available as a mitigation action in the Bot Managed ruleset and custom rules.
