Managed Microsoft Sentinel SIEM
SERVICE DESCRIPTION
Cynode "Managed Microsoft Sentinel SIEM" is a security operations service that delivers 24/7 monitoring, detection, incident investigation, and response for organisations using Microsoft Sentinel.
The service operates Microsoft Sentinel across the full operational lifecycle—from data ingestion and normalisation, through KQL-based analytics rules and incident investigation, to SOAR-driven response and incident closure. Cynode's SOC ensures that Sentinel remains effective and consistent as environments, data volumes, and operational demands evolve.
WHY IS THIS SERVICE IMPORTANT?
Microsoft Sentinel is a highly capable SIEM, but its long-term value depends on how it is operated over time. Detection logic must be maintained, response workflows must remain reliable, data ingestion must be efficient, and incidents must be handled consistently.
Cynode applies a detection-value-driven operating model to Sentinel, continuously tuning analytics rules, maintaining SOAR workflows, and aligning log ingestion with security outcomes—reducing ingestion costs by up to 75% compared to unselective approaches—while preserving effective detection and response.
