HENNGE One is a cloud security service from HENNGE K.K., founded in 1996, for large and mid-sized companies. Its Identity Edition provides single sign-on and access control for SaaS such as Microsoft 365 and Box, and other editions cover email and endpoints.

Single sign-on over SAML or OpenID Connect reaches hundreds of cloud services, with no per-service charge. Every integration is verified, with a setup manual. Access policies combine factors such as IP address, one-time password and certificate with AND and OR conditions per group. The HENNGE Lock app lets users approve sign-ins with one tap.

Certificates authorized by a third-party certification authority identify each device, so users sign in only from registered devices. The number included depends on the plan.

Users can be managed centrally in Active Directory, synced to Microsoft and Google, and created in SAML-connected services at first sign-in.

Higher plans add a password manager, a cloud reverse proxy and, on the top plan, zero trust network access (ZTNA). The DLP Edition (data loss prevention) holds outgoing email for approval and turns attachments into download links. The Cybersecurity Edition runs targeted-attack email drills, and upper tiers add managed endpoint detection and response (EDR).

An uptime SLA reduces the following year’s fee when monthly uptime misses its target. Every plan requires at least 200 IDs or devices, and contracts start with an inquiry.
