Everything your team needs

Send, request and verify sensitive information.

Send secure messages and files, request information through File Drop Pages, communicate with external recipients, manage company users and security, work in Microsoft Outlook, and verify message and file provenance.

At public launch, ordinary teams will be able to create a WSD SaaS workspace and start immediately. Technical controls such as tenant isolation, customer-specific encryption architecture and cryptographic evidence work behind the scenes.

01
image
Send secure messages

Write a message, attach files, and send sensitive data just like email, but with controlled access, client-side encryption, and provenance evidence.

02
image
Receive through File Drop Pages

Create secure File Drop Pages so people outside your organisation can send messages and files directly into your secure inbox without using insecure email attachments.

03
image
Store and organise in Secure Vaults

Use Secure Vaults for secure file storage, document organisation, client-side encrypted files, customer-controlled encryption keys, cryptographic provenance and secure sharing.

04

Prove origin and integrity

Generate cryptographic provenance so recipients can verify who sent a document, when it was sent, and whether it has been altered.

See how it works

Microsoft 365 workflow

Works where your teams already work: Microsoft Outlook

Users can create certified secure messages and securely attach large files from inside Outlook, while We Secure Data handles encryption, access control, audit trails and cryptographic proof behind the scenes.

Outlook is an entry point into the wider We Secure Data platform: secure messaging, secure file transfer, encrypted vaults, external replies, customer-controlled encryption and cryptographic provenance remain managed across the platform.

Secure attachments from Outlook

Replace risky email attachments with encrypted secure links, access controls and full audit history.

Certified secure messages

Send sensitive content with independent proof of sender, time and integrity.

Still the full WSData platform

Messages, files, vaults, provenance, external replies and customer-controlled encryption remain managed by the wider We Secure Data platform.

Secure File Drop Pages

Receive external messages and files into a secure inbox without asking clients, suppliers, or partners to use insecure email attachments.

Secure Vaults

Securely store, organise and share messages, files, attachments and provenance records in customer-controlled infrastructure.

Approval verification icon
Sign and approve any file

We Secure Data supports signatures and approvals for PDFs, spreadsheets, Word documents, ZIP files, CAD files and more, with cryptographic provenance tied to the exact file version.

Paper Key Access
Physical security. Digital simplicity.

Store access offline on a printed Paper Key and restore it in seconds by scanning the QR code.

Secure communication, protected before storage.

Traditional platforms often separate the conversation from the file and the evidence. We Secure Data keeps the message, attachments, sender context, access control, audit trail, and provenance evidence together.

Messages and attachments are encrypted client-side, with tenant separation, identity-based access and audit context across the hosted service.

We Secure Data operates the SaaS infrastructure, so your team can start without provisioning servers, a cloud project or KMS.

Secure Vaults provide secure file storage and organisation for messages, attachments, documents and provenance records. They support secure sharing without relying on generic public link-sharing folders.

Protect critical business communication with architecture that keeps control with the data owner.
