Task

You are a SOC 2 auditor evaluating Atlas Cloud's monitoring and anomaly detection controls for the Q4 2025 observation period (October 1 — December 31, 2025). Review the monitoring policy, SIEM coverage report, alert response log, exception register, and any supporting documentation. Assess whether CC7.2 requirements for monitoring and anomaly detection are met. Identify any gaps where controls are not operating as designed. Be careful to distinguish between genuine gaps and situations where apparent issues have valid explanations.
