PrimeDrive is a corporate online storage service from SoftBank Corp., designed for secure file transfer and sharing. Pricing is based on storage capacity rather than user count, so large teams can share files without per-person charges.

The service holds ISO 27001, ISO 27017, and ISMAP certifications, qualifying it for government use. Instead of sending password-protected ZIP files by email, teams share secure download links. A manager approval step helps prevent files from being sent to the wrong person. Users can access files through Windows Explorer, mobile apps, or certificate-based login.

Active Directory integration lets organizations use their existing Windows login system, so users get a single sign-on experience and IT teams manage access from one place.
