Application and API security are currently facing significant challenges, with traditional methods proving insufficient in today's complex and dynamic environments. The prevailing strategy, which relies on developers to address vulnerabilities while holding security operations accountable, is unsustainable. This session introduces the concept of Application Detection and Response (ADR) as a transformative approach. ADR shifts focus to detecting and responding to both attacks and vulnerabilities directly within production environments. By observing application behavior in real-time and building an "AppSec Graph," organizations gain a comprehensive, contextual view of security risks. This empowers more effective and efficient security practices, enabling faster incident response, streamlined testing, and accelerated feedback loops. We'll discuss how production data is critical for modern application security, and adopting ADR is essential for protecting applications in the face of evolving threats.
