イチオシ
1

Box

$47/user/mo Enterprise / custom Enterprise Plus

Purpose-built for enterprise content management with 1,500+ integrations.

おすすめの理由

Box Shield for threat detection, Box Governance for retention, and FedRAMP authorization make it the enterprise standard.

注意点

Expensive per-user cost and no bundled productivity suite; you still need Office or Google Workspace.

2

OneDrive

$36/user/mo M365 E3 (unlimited) / $57/user/mo E5

Unlimited storage with Microsoft 365 E3/E5, deeply integrated with the Microsoft security stack.

おすすめの理由

Unified DLP, Conditional Access, and Purview compliance across SharePoint, Teams, and OneDrive.

注意点

SharePoint backend can be confusing; folder structures get messy at scale without governance.

3

Google Drive

Custom pricing (typically $25-30/user/mo)

Google Workspace Enterprise offers unlimited storage and Vault for eDiscovery.

おすすめの理由

Google Vault, DLP, and Context-Aware Access provide enterprise security without third-party add-ons.

注意点

Enterprises in regulated industries often find Google's data processing agreements harder to negotiate than Microsoft's.

4

Dropbox

$24/user/mo unlimited

Dropbox Advanced adds smart sync, unlimited storage, and advanced admin controls.

おすすめの理由

Dropbox Replay for video review and Dropbox Sign for contracts add real workflow value.

注意点

Lacks the deep compliance certifications (FedRAMP, GovCloud) that Box and OneDrive offer.

5

Tresorit

Custom pricing enterprise

End-to-end encrypted storage for enterprises with strict data sovereignty requirements.

おすすめの理由

Swiss-hosted, zero-knowledge architecture satisfies EU data residency and GDPR requirements.

注意点

Small vendor risk; Tresorit lacks the ecosystem breadth and integration depth of Box or Microsoft.
