Editor's takeBox holds FedRAMP High authorization and DoD Impact Level 4 accreditation, a security tier few cloud storage competitors reach, alongside HIPAA and GxP support. It connects to over 1,500 apps, including deep native ties to Salesforce, Microsoft 365 and Google Workspace. Lower-tier Business plans cap single-file uploads at 5GB, and users consistently report slow syncing when handling large files or folders.
Is Box approved for government or defense use?
Yes. Box holds FedRAMP High Marketplace Designation and DoD Impact Level 4 accreditation from DISA, placing it among a small group of cloud content platforms cleared for sensitive government data.
Does Box have file size limits?
Yes, on lower tiers. The Business plan caps single-file uploads at 5GB and Business Plus at 15GB, which some users find restrictive for large media files.
