Microsoft Sentinel
Architecture, onboarding, data sources, analytics, automation and operational use.
Sentinel · Defender · KQL
Microsoft security engineering tied to operational outcomes.
I work across Microsoft Sentinel, Defender and KQL to improve detections, integrations, automation and the way security teams actually use the platform.
Capability
From platform design to analyst workflow.
Microsoft security environments often become complex quickly: data connectors, analytics rules, automation, workbooks, Defender signals, identity context and custom integrations all accumulate at different speeds.
I help simplify that complexity into a coherent operating capability.
Microsoft Defender
Improve how Defender signals and capabilities feed investigation and response workflows.
KQL
Detection logic, investigation queries, data validation and operational troubleshooting.
Detection engineering
Develop and improve detections with attention to fidelity, context and analyst handling.
Integrations
Connect identity, endpoint, cloud, network and third-party telemetry into useful analyst context.
Automation
Reduce repetitive steps while preserving accountability and clear decision points.
Principle
Deployment is not adoption.
A technically complete deployment can still produce a poor SOC experience. Rules can fire without useful context, automation can move work rather than remove it, and integrations can create volume without improving decisions.
I assess Microsoft security capability through the lens of the analyst and the service: what information is available at each step, where effort is duplicated, which signals deserve attention, and what can safely be automated.
Common engagement areas
- Sentinel architecture and operational review;
- detection quality and coverage assessment;
- KQL development and troubleshooting;
- Defender integration into SOC workflows;
- automation opportunities and control points;
- platform changes required during a SOC or MXDR transformation.
