Hello, I'm
Caio Freitas
Cybersecurity Architect — Microsoft Security
SOC Modernization • Microsoft Sentinel • Autonomous SOC • AI Security
Helping organizations modernize Security Operations through Microsoft Sentinel, Security Copilot, automation, and Cyber Resilience strategies.
About Me
// Security Architecture & SOC Operations
I'm a Cloud Solution Architect at Microsoft and Cybersecurity Architect with 10+ years of experience in technology, specializing in SOC modernization, SIEM/SOAR, and AI-powered security.
I lead end-to-end Microsoft Security engagements for large enterprise and public-sector customers in Brazil — including national institutions such as CNJ, MJSP, STJ, TJRJ, SEFAZ RS, METRO-SP, Petrobras (Transpetro), Sabesp and MPRJ.
My work focuses on SOC Assessments, SIEM/SOAR transformation, Microsoft Sentinel, Defender XDR, Security Copilot, and Cyber Resilience — connecting architecture, detection, automation, and operational evolution.
I was honored as an FY25 CSU Pace Setter, joining ~75 Cloud Solution Architects from 25+ countries at the global summit in Seattle — an experience that shapes how I bring global best practices back to Brazilian customers.
