Kiteworks buys WAMNET Japan to expand into enterprise security market

Kiteworks said Aug. 5, 2026, that it acquired WAMNET Japan K.K., giving the company its first direct presence in Japan’s enterprise security market. The deal brings more than 500 customers into Kiteworks’ ecosystem and sets a target of 2027 for ISMAP government cloud registration.

Why it matters: - The acquisition gives Kiteworks an immediate foothold in Japan, one of the world’s most security-conscious enterprise markets. - WAMNET Japan brings more than 500 enterprise customers and more than 25 years of local market experience. - Kiteworks gains a path to expand its data control plane, compliance framework and AI governance tools into Japan.

What happened: - Kiteworks acquired WAMNET Japan K.K. and said the deal establishes its first major direct presence in Japan. - The announcement came Aug. 5, 2026. - WAMNET Japan is a provider of secure data transfer and enterprise file sharing solutions.

The details: - WAMNET Japan products, including GigaCC and DIRECT! EXTREME, will continue to be sold and supported. - Current contracts, pricing and dedicated support remain unchanged. - Customer data will remain hosted in Japan. - WAMNET Japan customers will eventually get a supported upgrade path to the Kiteworks platform. - Kiteworks said the platform will bring its Data Policy Engine, hardened virtual appliance architecture, AI agent governance and unified compliance framework to Japan. - The Kiteworks Data Policy Engine enforces RBAC and ABAC policies in real time across agentic workflows and data exchange channels. - Kiteworks said the platform includes Email Protection Gateway, Secure Collaboration and File Transfer, Managed File Transfer, SFTP, Secure Data Forms, APIs and MCP connectors. - Kiteworks said its hardened architecture includes double encryption, an embedded network firewall, WAF, IDS and an assume-breach design. - Kiteworks said WAMNET Japan customers can use deployments on-premises, in private cloud or in public cloud. - Kiteworks said it is targeting ISMAP government cloud registration in 2027. - Kiteworks said it is also committed to registering for ISMAP, Japan’s government cloud security certification and procurement gateway. - Kiteworks said the company’s platform is FedRAMP Moderate Authorized, FedRAMP High In Process, SOC 2 Type II, and ISO 27001/27002/27018 certified, with validations including FIPS 140-3, IRAP, BSI and Cyber Essentials Plus. - WAMNET Japan products are already ISMS (ISO 27001), ISMS Cloud Security and Privacy Mark certified.

Between the lines: - The deal pairs a local Japanese vendor with a global security platform, which may help Kiteworks address sovereignty and procurement requirements more quickly than a greenfield launch. - Kiteworks is also positioning the acquisition around AI governance, signaling that data control is becoming part of enterprise AI adoption, not just file transfer. - The continued support for existing WAMNET products lowers migration risk for current customers.

What's next: - Kiteworks will localize its control plane for secure data exchange into Japanese. - WAMNET Japan customers will be offered a gradual upgrade path to Kiteworks. - Kiteworks will work toward ISMAP registration in 2027.

The bottom line: - Kiteworks is using WAMNET Japan to enter Japan with an installed customer base, local support continuity and a compliance-first pitch.
