SendSafely vs Box

An end-to-end encrypted alternative to Box for encrypted file storage.

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.

At a glance

Two products, different jobs.

A side-by-side picture of what Box is built for, and where SendSafely is built differently.

What Box does well
  • Familiar drive interface and OS sync clients for ongoing collaboration
  • Mature marketplace of editing, signing, and workflow apps
  • Strong enterprise content-management story for files that don't need end-to-end encryption
Where SendSafely is different
  • Split-key encryption, not server-side at rest. 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.
  • Recipients verify identity, no account needed. 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.
  • Built into the tools your team already uses. 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.

Why teams choose SendSafely

Four architectural differences that matter.

01

Split-key encryption, not server-side at rest

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.

02

Recipients verify identity, no account needed

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.

03

Built into the tools your team already uses

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.

Who switches

Teams moving from Box to SendSafely.

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.

  • Legal teams sending diligence packages to outside counsel
  • Healthcare exchanging PHI with covered entities and business associates under HIPAA
  • Finance moving deal documents, KYC files, audit responses to regulated counterparties
  • Customer support collecting screenshots, logs, and ID documents inside helpdesk tickets

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.

Enterprise controls

Deep admin control, built in.

Policy, identity, storage, and automation controls for teams that answer to auditors.

Multi-Portal Administration

Run every portal you manage, across subsidiaries, regions, or sandbox and production, from one login. No standing admin accounts, and every action lands in that portal's audit log.

Enterprise

Security Groups

Decide who can send outbound, own Workspaces and Dropzones, or generate API keys. Everyone else stays receive-only, across every integration.

Business · Enterprise

Bring your own bucket

Store encrypted files in an AWS S3 bucket you control, or host in the US, EU, or Sydney. Custody of your data, with nothing to run on your perimeter.

Business · Enterprise

Enforced Workspace expiration

Set default, minimum, and maximum file expiration for every Workspace in the portal, then exempt only the named accounts that need longer.

IP restrictions

Limit registered users to your office or VPN ranges on every path: web, integrations, REST API, and SCIM. Guests are unaffected.

Enterprise

SSO and SCIM

SAML SSO with any SAML 2.0 identity provider. SCIM provisioning for Okta and Entra ID, including admin rights managed from Okta.

Audit Log API

Stream every send, download, and admin action to Splunk, Sentinel, or Chronicle, with long-term retention through S3 export.

Enterprise

Actions

Scan every inbound file with CrowdStrike, OPSWAT, or Sophos, check it with Google Cloud DLP, and quarantine, hold, or archive it automatically.

Enterprise

Native integrations

Encryption inside Outlook, Gmail, Zendesk, Salesforce, Intercom, Freshdesk, and Slack, plus a REST API for everything else.
Audited and compliant

The same controls regulated procurement asks for.

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.

How our architecture works Compliance & certifications
