Business Consulting and Services Barueri, São Paulo 501–1,000 employees Privately Held

SEK operates a security services platform across five countries in Latin America, managing over 800 client relationships through five dedicated defense and response centers. The tech stack is heavily SIEM and endpoint-detection focused—Splunk, QRadar, Sentinel, CrowdStrike, Cortex XDR—with AWS cloud infrastructure and supporting tools like Securonix and CASB for surface area coverage. Active hiring is concentrated in security roles (32 positions), with senior-level hiring outpacing junior, indicating a services business scaling expert capacity rather than building product. Pain-point data reveals internal operational challenges: false positive reduction, SLA consistency, and automation gaps are being addressed in parallel with market-side demand generation.
