Log Engineering for Microsoft Sentinel
SERVICE DESCRIPTION
Log Engineering for Microsoft Sentinel optimises telemetry ingestion, tiering, and retention to reduce costs while maintaining security visibility. It delivers a clean, governed data foundation that enables effective detection and investigation at scale, ensuring operational efficiency and long-term cost predictability.
WHY IS THIS SERVICE IMPORTANT?
Optimised logging enables Sentinel to deliver effective detection, investigation, and response without unnecessary ingestion. A deliberate log optimisation strategy ensures clear alignment between logs and their purpose—whether for detection, investigation, hunting, or compliance. It delivers predictable Sentinel costs that scale with operational value, faster queries that enable more efficient investigations, and retention policies aligned with governance and regulatory needs.
MITRE ATT&CK is used as one of several guiding frameworks, alongside real operational workflows and investigation patterns, to validate coverage and guide decision-making. Continual optimisation keeps Sentinel cost-efficient, performant, and operationally effective as environments evolve.
WHAT THE SERVICE DELIVERS
-
Review of all onboarded telemetry to understand its role in detection, investigation, hunting, automation, and compliance. Logs are mapped to MITRE ATT&CK where appropriate to validate adversary coverage.
-
Logs are mapped to Analytics, Basic, or Archive tiers based on usage, investigation value, compliance requirements, and detection dependencies.
-
Refinement of filtering, transformation, and routing logic to prioritise high-value telemetry and reduce redundant ingestion.
-
Establishment of ingestion baselines, tagging standards, and cost-tracking mechanisms for long-term control and transparency.
KEY BENEFITS
-
Reduced Sentinel ingestion and storage costs
-
Clear visibility into log value and purpose
-
Faster queries and investigations
-
Retention aligned with compliance needs
-
Sustainable governance that prevents cost regression
WHO SHOULD USE IT
-
Organisations scaling Microsoft Sentinel across cloud, identity, endpoint, and SaaS
-
Security teams seeking efficiency without reducing visibility
-
SOCs preparing for MDR, co-managed, or internal operations
-
Environments needing cost control without detection loss
UPGRADE PATH
From Log Engineering to SIEM Engineering
Microsoft Sentinel Log Engineering establishes a clean, intentional telemetry foundation. Once log ingestion, tiering, and governance are optimised, many organisations choose to extend into full-scope Sentinel engineering.
The Engineering Service for Microsoft Sentinel SIEM builds on this foundation by taking responsibility for how that telemetry is used, maintained, and evolved across detections, automation, integrations, and governance. Explore here more.
