Exceeding 3,000 Companies in Approximately 3 Years and 4 Months Since Official Release
The browser-based business file transfer service "Kozutumi" was officially released on November 30, 2022. Following its achievement of 2,000 users in September 2024, it has continued to expand its market share, surpassing 3,000 users in April 2026.
The movement to abolish and reject emails with attached files, which are often entry points for information leaks and cyberattacks, such as "PPAP (sending password-protected ZIP files)," is accelerating among central government ministries and general corporations.
As abandoning PPAP, including measures against malware and ransomware, becomes increasingly crucial for companies of all sizes, "Kozutumi" has been chosen by many businesses for its ease of intuitive introduction and operation, even for companies without an IT department, and its high-level security.
Furthermore, in February 2026, the company officially released its new feature, "Archive Option for Audits," which enables long-term storage of all sent and received files and sets a new standard for audit support, demonstrating its continuous updates to meet the advanced compliance and security demands of its users.
