Microsoft Sentinel Security Services
Microsoft Sentinel gives you visibility across your environment, but only if the right data is connected and the right questions are being asked.
GEMXIT helps businesses plan, review and improve Microsoft Sentinel so security teams can investigate incidents, understand patterns and build better response workflows.
This includes data connectors, analytics rules, workbooks, KQL queries and practical security operations design.

What Microsoft Sentinel adds
Microsoft Sentinel provides cloud-native SIEM and SOAR capabilities for collecting, correlating and investigating security events across the environment.
Centralised security visibility
Bring identity, endpoint, firewall, cloud and Microsoft 365 logs into one investigation plane.
Analytics rules
Turn important patterns into scheduled detections and incidents.
Workbooks and reporting
Visualise trends, gaps, incidents and security posture in a way decision-makers can understand.
Practical KQL example: after-hours activity
Not every incident starts with malware. Sometimes the first signal is activity happening at a time that does not match normal business behaviour.

Used for
Finding sign-ins that may be legitimate but deserve review because of timing.
Best pivot
Compare location, device, application, conditional access and user history.
Why it matters
Good detection often starts with behaviour, not malware signatures.
Sentinel setup areas GEMXIT can review
Sentinel value depends on the right data connectors, analytics rules, workbooks, retention and response process.
Data connectors
Validate which logs are connected and whether important sources are missing.
Rules and incidents
Review analytics coverage, noisy detections and practical incident workflow.
SOC-style visibility
Build workbooks and dashboards that make security posture easier to understand.
