What 株式会社クロスサイド/CrossSide,Inc. does
株式会社クロスサイド (CrossSide, Inc.) is a privately held Japanese IT infrastructure systems integrator headquartered in Chuo-ku, Tokyo. Founded in 2015, the firm operates with a small team of approximately 6 employees whose stated philosophy is to build a 'high-quality engineer group' (質の高いエンジニア集団). CrossSide serves Japanese large enterprises, government agencies, and major organizations, delivering project-based professional services across three service lines: Integration Services (network design, construction, and infrastructure virtualization), Cloud Services (cloud network design, AWS migration, and cloud-managed wireless for educational institutions), and Training Services (hands-on physical-equipment configuration training). Documented customers include a Japanese government agency (NW operations automation), a major automotive manufacturer (overseas office network redesign), a cryptocurrency business (security design through operations), a major telecom carrier (on-premise to AWS migration), an educational institution (cloud-managed wireless deployment), and a major SIer (internal TAC-style technical support).
The company's core technology stack is built around VMware NSX-T for network virtualization, Ansible for network operations automation, Avi Networks load balancing, VMware SD-WAN (Velocloud) for multi-site deployments, and AWS for cloud migration — with documented engagements spanning Zero Trust architecture via NSX-V micro-segmentation, multi-site SD-WAN VPN configuration, and NSX-V to NSX-T migration support. Engineering quality is signaled by senior-level certifications held by staff, including CCIE Enterprise Infrastructure, VCIX-NV (Network Virtualization), CCNP ENSDWI, and multiple AWS certifications (CLF, SAA, SOA, ANS). The firm does not develop proprietary software products; revenue is generated entirely through professional services engagements and hands-on training, sold through direct enterprise sales with project-based pricing. Demand generation is conducted almost exclusively through an extensive Japanese-language technical blog and a public works/case-study portfolio rather than paid marketing.
