Defender Lens is a detection control plane that provides CI/CD capabilities for detection engineering across multiple security platforms. The platform addresses common challenges in detection and response operations, including detection reliability, scalability across tools, rule volume management, and contextual awareness. The solution operates as a centralized system for managing detections across SIEM, XDR, and data lake environments. It enables organizations to deploy detection rules consistently across different security tools and platforms from a single control point. According to the SANS 2025 Detection and Response Survey referenced on their site, the platform targets key pain points where 73% of teams struggle with detection reliability, 55% cannot scale across tools, 54% are overwhelmed by rule volume, and 50% lack context in their detection operations. The platform positions itself as a detection control plane that brings software development practices to security detection engineering, allowing teams to manage detections as code with version control, testing, and deployment automation across heterogeneous security infrastructure.
