KDDI America

KDDI America is the U.S. subsidiary of KDDI Corporation, a Japanese telecom giant operating across more than 100 countries. Founded in 1989, the company provides international IT and communications solutions - networks, data centers, system integration, managed services, cloud, and cybersecurity - to enterprise clients in sectors like manufacturing, financial institutions, logistics, and consumer goods. Its Ethernet network claims uptime exceeding 99.999% between regions, a number that matters when you're running infrastructure that can't afford to blink.

The cybersecurity practice sits within a broader technical stack that includes IoT and connected car solutions - domains where the attack surface is physical, not just digital. Think industrial control systems, vehicle telematics, and the kind of supply-chain complexity that keeps CISOs up at night. The team operates across New York and Los Angeles, supporting clients whose operations span continents and regulatory regimes.

For security professionals, the draw is the scope: you're not defending a single product but an infrastructure layer that other enterprises depend on. The threat model here involves nation-state actors targeting telecom infrastructure, lateral movement across converged IT/OT environments, and the persistent challenge of securing managed services at scale. The tooling and domains are enterprise-grade, and the work is less about perimeter defense and more about resilience across a sprawling, interconnected stack.
