What Qualitia does

Qualitia Co., Ltd. (株式会社クオリティア) is a Tokyo-based, privately held Japanese software company specializing in email and email-security solutions for the Japanese enterprise and public-sector markets. The company was formed through a 2015 merger of TransWARE (株式会社トランズウェア) and Deepsoft Co., Ltd. (ディープソフト株式会社), consolidating two predecessor email software vendors under a single corporate entity. Qualitia offers a dual cloud-and-on-premises portfolio organized under the Active! brand family: Active! gate SS for email misdelivery prevention (No. 1 in Japan sales share for 5 consecutive years per Deloitte Tohmatsu MIC Research Institute), Active! vault SS for email archiving (No. 1 for 8 consecutive years), Active! zone SS for targeted email attack countermeasures with sandbox analysis (adopted by 400+ local governments), dmt for targeted-attack email training with approximately 200 scenarios, Active! world for spam- and virus-protected webmail, and QUALITIA CLOUD as a unified email, web conferencing, and chat platform. On-premises counterparts (Active! gate, Active! zone, Active! hunter, Active! vault, Active! mail, DEEPMail, MailSuite) have collectively been deployed across 43.5 million cumulative accounts covering 2,250+ corporations, ISPs, educational institutions, and government agencies.

The underlying technology stack combines proprietary email-processing engines with native integrations to Microsoft 365, Google Workspace, and LINE WORKS, file-sanitization partnerships with OPSWAT MetaDefender Core, VOTIRO Disarmer, Sanitizer, and FileZen S, and a patented TLS Verification Function (patent granted January 2026) that addresses the PPAP (password-protected ZIP attachment) attack pattern. Revenue is generated through a mix of recurring cloud subscriptions (monthly/annual billing starting at 150 yen per account per month for Active! gate SS), one-time on-premises perpetual licenses, professional services for enterprise implementation, and OEM/channel partner distribution via KDDI Web Communications, Airnet, and Asahi Kasei Direct. Go-to-market combines direct enterprise sales, a reseller/VAR network, webinar- and event-driven demand generation, and content marketing through the POSTIA media platform. The customer base is diversified across Japanese general enterprises, public-sector institutions, ISPs, and education, with disclosed logos spanning entertainment (Yoshimoto), broadcasting (CHUKYO TV), e-commerce (au Commerce & Life, CyberAgent, GEO), and healthcare (Alcare). Qualitia holds ISO/IEC 27001, 27017, 27018, and 27701 certifications, is privately held with no disclosed external institutional investors, and operates almost exclusively in the Japanese domestic market.
