Threat intelligence and incident response for critical infrastructure in Japan

Computer and Network Security Chiyoda-ku, Tokyo 11–50 employees Founded 2017 Privately Held

Nihon Cyber Defence operates a security operations stack built on Wazuh, Elastic Stack, Splunk, and EDR/XDR—the core SIEM and detection layer for monitoring critical infrastructure. The hiring pattern (3 security, 2 sales over 30 days) reflects a security-first org scaling operational depth, with active projects centered on SOC construction and SIEM/EDR implementation strategy. Pain points around SIEM architecture adaptation and incident response maturity suggest the team is moving beyond basic monitoring into proactive threat hunting and response automation.
