GigaCC ASP is an enterprise file transfer and sharing service from Japan Wamnet Inc., developed and operated entirely within Japan. It combines file sending, file sharing, and shared notes into a single platform, with a broad deployment track record across industries including manufacturing, finance, and legal.

Three plan tiers (Standard, Advanced, Premium) let organizations select their security level. Advanced plans include supervisor approval workflows, IP address restrictions, two-factor authentication, forced ZIP encryption, and recipient restriction controls. The service holds Privacy Mark and ISMS (ISO 27001) certifications along with JIIMA Electronic Transaction Software certification for compliance with the Electronic Books Preservation Act. A Global Gateway option optimizes file transfer routes for overseas exchanges, and command-line tools and WebAPI support automated integration with business systems.

The admin panel and user interface are available in Japanese, English, and Chinese (Simplified).
