Box is built for broad enterprise collaboration. SendSafely is built for the moments where the data shouldn't sit in your service vendor's cloud at all — split-key encrypted client-side, with verified recipients on the other end.
A side-by-side picture of what Box is built for, and where SendSafely is built differently.
Each row reflects how the two products approach the same problem. Both companies maintain their own certifications and audit programs — consult each vendor's public documentation for current capabilities.
| Feature | SendSafely | Box |
|---|---|---|
| End-to-end encryption (client-side, before upload) | Every file, every product surface | Encrypted at rest server-side; Box holds the keys |
| Split-key architecture (no admin path to plaintext) | Yes — sender + recipient halves, never combined on a server | No — Box admins and the service can decrypt |
| Max file size per send | Up to 100 GB | Up to 150 GB on Enterprise plans |
| Recipient account required | No — link plus identity verification | Sharing externally varies by plan and policy |
| Native helpdesk + email plug-ins included | Zendesk, Salesforce, Intercom, Freshdesk, Outlook, Gmail | Sold as add-ons or through third-party apps |
| SOC 2 Type 2, HIPAA BAA, PCI DSS, GDPR, CCPA | All covered | All covered |
| Audit log API for SIEM | REST endpoint with PACKAGE_EVENT, ADMIN_EVENT, USER_EVENT | Available on Enterprise and above |

Box encrypts content at rest with keys Box manages. SendSafely encrypts on the sender's device with OpenPGP, and the decryption key is split so neither SendSafely nor any vendor in the path can read the contents on its own.
External parties don't need a Box account or a license. They click a one-time link, verify identity (email or SMS), and decrypt locally.
Native Outlook plug-in, Gmail extension, Zendesk app, Salesforce app, Intercom app, Freshdesk app, REST API, plus HALO for AI chat. Encryption follows the workflow instead of replacing it.
Teams moving sensitive workflows off Box typically aren't replacing Box — they're carving the regulated, externally-shared subset of their file traffic into a system where the vendor itself can't read the content.
Most teams keep Box for everyday collaboration and move the regulated subset into encrypted storage or a shared Workspace. Unity did exactly that — secrets out of email, Slack, Zendesk, and Jira, without replacing the tools underneath.
Every file is encrypted on the sender's device using OpenPGP. SendSafely sees ciphertext only — the decryption key is split so nobody, not even SendSafely, can read the contents on its own.
Audited annually. SendSafely maintains the certifications regulated industries require.
