What SCSK Security Corporation does
SCSK Security Corporation (SCSKセキュリティ株式会社) is a Japan-based cybersecurity services subsidiary wholly owned by SCSK Corporation, founded August 1, 2023 and operating from Koto-ku, Toyosu, Tokyo. The company serves large Japanese enterprises with a horizontally-segmented go-to-market across manufacturing, finance, pharma, consumer goods, food, chemicals, education, and broadcasting. Named customers include Lion Corporation, Bourbon, Iwase Cosfa, Maruho, Credit Engine, NOK (110+ domestic sites, 11 overseas countries, 30+ sites), Kinki University, and TVer. The company operates a three-revenue-stream business model: (1) professional services (security consulting, CSIRT building, vulnerability diagnosis, penetration testing); (2) product distribution (one-time licenses for Palo Alto Networks, Cato Networks, F5, Splunk, Ivanti, and others); and (3) managed services (24/7 MSS, MSS-AUTO, MDR, and Managed SIEM) operated from the SCSK Security SOC. Pricing is subscription- and contract-based: SCSK Security Retainer Basic starts at ¥990K/year, ASM service from ¥1.3M, and Prisma Browser implementation from ¥2.2M + license on multi-year terms.
The technical architecture is a platform-plus-services model: SCSK Security does not build proprietary security products but integrates best-of-breed vendor stacks (Cortex XSIAM/XDR, Cato Cloud SASE, Cisco XDR/Duo/Secure Access, F5 Distributed Cloud WAAP, Splunk, Google SecOps, FortiSIEM, IBM QRadar, Ivanti Neurons) into a unified SOC operations layer. Proprietary elements include MSS-derived automation rules (MSS-AUTO), AI/ML-augmented alert analysis on Cortex XSIAM, CardinalOps-based MITRE ATT&CK rule generation, and a Dark Web monitoring pipeline built on Searchlight Cyber's intelligence lake refreshed hourly. The company holds the only Japan-domestic Unit42 Cyber Risk Management Proficiency certification and is a Cato Networks MSP Advanced Partner with 4 consecutive years of highest Japan new-logo revenue (2022–2025).
In April 2026, SCSK Security absorbed Net One Systems' security services business and a partial carve-out from parent SCSK Corporation via absorption-type company split, materially expanding headcount, customer base, and operational capability. The company is also pursuing a planned corporate rename in April 2027 as part of its "Vision Link" brand strategy, and targets ¥1B annual revenue with 300 domestic contracts by 2030. Certifications include JIS Q 15001 (privacy) and ISO 27001 (information security).
