Focus

Less noise.
More signal.

Four areas, one goal: an analyst should only see an alert when it's worth their time.

01

Detection engineering

Analytics rules written, tuned and mapped to MITRE ATT&CK, with false-positive budgets and test cases behind every one.

02

Telemetry engineering

Onboarding and shaping the data first: FortiGate and Palo Alto firewalls over CEF/Syslog via AMA, Arc-connected servers, DCR transforms, and ingestion cost under control.

03

Security automation

Playbooks and API-driven enrichment that close the easy incidents automatically and hand analysts a head start on the rest.

Logic AppsGraph APIEnrichment
04

Validation & research

Controlled attack simulations that prove a detection fires, plus research that turns new attacker techniques into rules.

What the SOC
actually looks at.

Example Sentinel workbooks: SOC posture, firewall telemetry from FortiGate and Palo Alto, and identity risk. Synthetic data.

run end to end.

Pick a scenario. Each one walks from raw events to a correlated incident using synthetic data only.
