Essential Data Sources for Detection Beyond the Endpoint

Threat actors are now moving 4x faster to exfiltration than in 2025, exploiting blind spots created by over-reliance on endpoint data. In 75% of investigated incidents, critical evidence of the initial intrusion existed in logs but wasn't operationalized. Three key failure scenarios are outlined: cloud-to-endpoint pivots invisible to EDR, covert C2 via DNS tunneling combined with credential theft, and rogue/unmanaged assets lacking security agents. The recommended solution is a unified, AI-driven SOC platform (like Cortex XSIAM) that consolidates logs from all IT zones into a single repository, enabling alert stitching, ML-based incident scoring, and user behavior analytics to detect threats across the full attack surface.
