SIS

What SIS does

SIS Co., Ltd. (エス・アイ・エス株式会社) is a privately held Japanese IT services company founded in July 2004 and headquartered in Osaka, with additional offices in Tokyo and Fukuoka. The company operates four business solution divisions: Development Solution (ERP, business applications, IoT/embedded systems), Operation Solution (IT infrastructure and system operations delivered on-site at client sites), Business Solution (security management outsourcing for financial institutions including PMO security manager placement and FISC-compliant documentation), and System Solution (J-SOX and IT general controls consulting). Its core differentiation is specialized security and regulatory compliance expertise for financial institutions, supported by proprietary FISC-compliant documentation templates and a Privacy Mark certification obtained in December 2021.

The company generates revenue primarily through professional services delivery, deploying engineers on-site at client locations for system development, operations, maintenance, and security management. Customer segments are split between two primary verticals: financial institutions (banks, securities firms) requiring ISMS, FISC, and J-SOX compliance support, and enterprise IT departments needing system development and infrastructure management. The company holds a worker dispatch business permit (派27-302909), enabling engineer dispatch as a service line. Disclosed salary benchmarks indicate mid-career security management roles command ¥300,000-¥400,000/month, reflecting the specialized nature of the work.

SIS is a small, bootstrapped company with 75 employees, ¥34 million in registered capital built entirely through internal accumulation, and no external funding rounds. The company is led by founder and Representative Director Takagi Minoru (高木 実), who has served since inception and is a member of the Japan System Auditor Association, System Audit Society, and Japan Security Management Society. Geographic reach is concentrated in Japan across the Kansai, Kanto, and Kyushu regions, with no disclosed international operations. Engagement is primarily direct enterprise sales supplemented by job fair participation (Osaka Job Fair, Mynavi) and an external recruitment platform (en-gage) for talent acquisition, with the company noting it does not engage in consumer retail or e-commerce.
