Managed security services and GRC platform with 24/7 threat operations

Information Technology & Services Santa Clara, California 501–1,000 employees Privately Held

Hitachi Cyber operates a managed security services business built on SIEM, Microsoft Sentinel, and custom automation (Python, Bash, Ansible). Their active project list—incident response workflows, false-positive reduction, Sentinel deployment at scale, and threat hunting—reveals an organization investing heavily in operational maturity rather than new product development. Security-dominant hiring and a documented pain around incident triage and detection accuracy suggest they're scaling SOC capabilities in parallel with platform consolidation.
