HENNGE One

HENNGE K.K. is a Japanese cloud security company founded on 5 November 1996 and headquartered in Shibuya, Tokyo. It helps organizations adopt SaaS such as Microsoft 365 and Google Workspace safely by controlling who can sign in, from which device, and how information leaves the company.

HENNGE One is a cloud security service sold in editions. The Identity Edition provides single sign-on across many systems, multi-factor authentication and access policies that block unauthorized logins. The DLP Edition controls information shared by email and cloud storage with rules, double checks, audits and suspension of shared links, while the Cybersecurity Edition detects and quarantines suspicious emails and files and runs ongoing email training. The service connects to more than 463 cloud services and is used by over 3,800 companies.

• Single sign-on: Gives users one identity to access more than 463 supported cloud services.
• Multi-factor authentication: Adds a second factor to logins to stop credential theft.
• Access control: Blocks unauthorized access based on user, device and network conditions.
• Email and cloud DLP: Applies rules, double checks and audits to emails and shared files.
• Threat protection: Detects, quarantines and sanitizes suspicious emails and attachments.
• Security training: Runs ongoing email phishing training for employees.

A Japanese-invested manufacturer in Vietnam can give office staff one login with MFA for Microsoft 365 and other SaaS while blocking access from personal devices. A bank or securities firm can add email double checks and audits to prevent misdirected customer data. A retail chain can run phishing training for store managers.

Employees use one login with MFA for hundreds of SaaS applications, reducing password sprawl and help desk load. Access policies block sign-ins from unauthorized users and devices, lowering the risk of account takeover. Built-in email DLP and threat protection reduce misdirected emails and phishing incidents. The vendor commits to 99.9% monthly availability and reduces the next year's fee if it falls short.

As companies across Asia move email and collaboration to Microsoft 365 and Google Workspace, identity becomes the main security perimeter and SSO with MFA is now a baseline control. Vietnamese enterprises adopting many SaaS tools face the same need to centralize logins and prevent data leaks through email.

(US) and HENNGE AI K.K. Listed in Tokyo and moving to the TSE Prime Market in 2026. HENNGE One is ranked No. 1 in Japan's cloud security market by ITR and won a 2021 Good Design Award.
