SHARERN is a corporate cloud storage service from Nihon Wamnet, designed to help enterprises move from local file servers and network-attached storage to the cloud. Built on the company’s experience running the GigaCC file transfer platform, it targets organizations that need strong security and oversight.

The service keeps existing folder layouts and access rules intact during migration, so teams can switch without disruption. Fine-grained access controls, IP address restrictions, detailed activity logs, and malware scanning meet the needs of regulated industries. Two-factor authentication and single sign-on are both available. A free trial is offered for organizations testing the service.
