Encrypted storage

Encrypted storage with controlled sharing.

Workspaces are persistent encrypted folders for the files your team needs to keep — with granular per-member permissions, version history, and a full audit trail. End-to-end encryption is the default.

The problem

Purpose-built for handling highly sensitive information

Most file-storage platforms are optimized for collaboration only, with security as a distant secondary concern. SendSafely is purpose-built for handling highly sensitive information, with additional security controls, governance, and audit capabilities beyond what general-purpose file sharing provides.

No Encryption or Vendor Managed Keys

Most file-sharing platforms do not encrypt your data at all, primarily so they can use their own AI and data analysis tools to assess the contents of your files. If they do encrypt, it's often using encryption keys they manage, meaning they (or any future bad actor who compromises them) can decrypt all your customer data. SendSafely's end-to-end encryption keeps decryption in the hands of your authorized users only.

Stronger sharing controls

Traditional file-sharing platforms are built to make sharing frictionless. A shared link can be forwarded, copied, or remain active longer than intended. When the files contain sensitive customer records,  organizations need stronger controls over who can view, download, and retain access.

Sensitive data shouldn't live forever

Sensitive files shouldn't live forever. Automated expiration and deletion of sensitive data is one of the best, yet most often overlooked security controls an organization can use to protect itself and its customers. Ensuring sensitive information is only available for as long as it's needed is the best way to reduce blast radius associated with any future security events.

How Workspaces works

An encrypted folder, with the controls a security team expects.

Create a Workspace, add files, invite members with the permissions you choose. Every file is encrypted client-side before upload, every action is logged, and access can be revoked the moment a project ends or a contributor leaves.

1
Create a Workspace

Spin up an encrypted folder with a name, scope, and initial members. Each Workspace gets its own keyset and lives separately from the rest of your storage.

2
Add files, encrypted client‑side

Drag files in through the web UI or push them via the API. Every file is end-to-end encrypted in the browser before it leaves the device.

3
Grant granular access

Invite members as Viewer, Contributor, or Admin. Scope access to specific subfolders. Revoke a member and they immediately lose decryption rights — no shared link to track down.

4
Audit every action

Every upload, download, permission change, and version rollback is recorded with user, timestamp, and IP. Export to CSV or stream events into your SIEM.

What you get

The controls security and compliance teams ask for.

Workspaces combines end-to-end encryption, granular access controls, comprehensive audit trails, and automatic file expiration in a platform purpose-built for exchanging and managing sensitive data.

End-to-end encryption with split-key architecture

Files are encrypted in the browser with a 256-bit Client Secret before they hit our infrastructure. The decryption key is split between you and SendSafely — nobody, not even SendSafely, can read your files.

Granular per-member permissions

Assign Viewer, Contributor, and Manager roles with folder-level access controls. Give external partners, internal employees, and contractors access only to the files and folders they need.

Full audit trail per file action

Every upload, download, view, permission change, and version update is logged with user, timestamp, and IP. Export to CSV, stream via webhook, or query through the API.

Files up to 100 GB

Chunked, resumable uploads handle anything from a 50 KB signed PDF to a 100 GB backup archive on Enterprise. No off-platform handoffs for "big" files.

Version history on every upload

Every upload creates a new version while preserving a complete file history. Share only the latest version with collaborators or restore an earlier version when needed. Every version remains encrypted and fully auditable.

API and SDK access

REST API with SDKs for Node.js, Python, Java, and .NET. Create Workspaces, move files between directories, manage members, and log audit events in your own systems.

Where teams use it

Built for the files that can't sit in generic file shares.

Whenever sensitive files need to live somewhere with controlled sharing — internal, external, or programmatic — Workspaces is the encrypted home for them.

Long-term encrypted document storage

Legal hold, M&A data rooms, regulatory archives, and signed-contract repositories. Files stay encrypted for as long as you keep them, with audit trails that survive review years later.

External collaboration with vendors and auditors

Invite contractors, outside counsel, penetration testers, or auditors into a scoped Workspace. They get the files they need, you get the audit trail, and access ends the moment the engagement does.

Internal-only encrypted storage with audit

Finance close binders, HR investigations, incident-response evidence, board materials. Files that should never leave the company, with per-member access and an audit log your compliance team can lean on.

Programmatic encrypted storage via API

Back-end services that need to land sensitive output somewhere encrypted — claims attachments, signed customer documents, KYC packages. Push to a Workspace through the API.

Workspaces is one product inside the SendSafely platform. The same encryption, audit, and access model extends to Send & Receive, the embedded Dropzone widget, and the Developer API. Unity uses it to keep secrets out of email, Slack, Zendesk, and Jira.
