Surviving the Mythos Era: Richard Bejtlich Calls for Network Detection & Response to Close Investigation Gaps
What Happened — In a recent interview, veteran security analyst Richard Bejtlich highlighted that despite abundant telemetry, many SOC teams still struggle to answer the core investigative questions: “What happened? What evidence do we have? How do we know we’re seeing it all, in context?” He argues that relying solely on alerts is insufficient and that Network Detection and Response (NDR) platforms are essential for providing the missing context and continuous evidence needed for thorough incident investigations.
Why It Matters for Compliance & Audit Readiness
- SOC 2 auditors expect documented evidence that security events are detected, investigated, and resolved in a repeatable, auditable manner; NDR supplies the telemetry and contextual data needed to satisfy CC6.3 (Security Incident Management) and CC6.4 (Monitoring).
- Continuous evidence collection from NDR feeds creates a defensible audit trail, reducing reliance on ad‑hoc alert triage and supporting real‑time control monitoring.
- Mapping NDR capabilities to your control framework demonstrates due‑diligence in third‑party risk and incident response, a key artifact for the Trust Services Criteria.
Who Is Affected – Organizations with security operations centers, particularly SaaS providers, cloud‑native enterprises, and any firm subject to SOC 2 or similar trust‑service audits.
Recommended Actions
- Align your incident‑response playbooks with SOC 2 CC6.3/CC6.4 requirements and explicitly reference NDR‑derived evidence.
- Deploy an NDR solution that integrates with your SIEM/SOAR to automatically capture packet‑level context for alerts.
- Establish a continuous‑evidence pipeline that archives NDR logs for audit‑ready retrieval.

Technical Notes – The discussion centers on investigative methodology rather than a specific vulnerability or exploit. No CVEs or data exfiltration were reported. The focus is on the detection gap caused by over‑reliance on alert‑centric workflows. Source: same as above
