Security & Architecture

Technical assurance for verifiable communication

We Secure Data SaaS

We Secure Data SaaS is hosted and operated by We Secure Data. Messages and files are encrypted in the browser before storage, with organisation boundaries, identity-based access, audit records and cryptographic provenance built into the workflow.

Starter, Professional and Business customers use the managed SaaS service without provisioning their own cloud project, KMS or dedicated infrastructure.

DISTINCT KEYS. DISTINCT SECURITY PURPOSES.

Company-specific provenance keys

Each company’s supported message and file provenance is signed under its own key, rather than a provenance key shared across tenants. In hosted SaaS, authorised We Secure Data services invoke company-specific ECDSA signing keys in managed Cloud KMS. Company ownership checks select the right key; cloud access controls protect signing operations.

The private signing component stays in the managed key service. This operational model is separate from customer-held offline recovery keys.

Encryption keys

Protect content confidentiality. File encryption and key wrapping keep encrypted data separate from its usable decryption keys.

Provenance signing keys

Create verifiable signatures over covered evidence and file fingerprints. Public keys enable integrity and key-based origin checks.

Recovery keys

Unlock applicable encrypted backup packages. Customer-controlled recovery uses a separately held private recovery key and password.

BUSINESS CONTINUITY · YOUR OWN RECOVERY

Recovery that doesn't depend on your SaaS provider.

Keep a recoverable copy of your business information under your own control. Business includes Independent Backup & Offline Recovery: encrypted packages you can retain and open on your own Windows or Mac computer, independently of We Secure Data’s hosted availability.

Explore Independent Recovery

Your complete offline recovery kit

Save the complete downloaded package, its verification key and Recovery Desktop. Keep the matching private recovery key and password securely under your control, together with any additional customer-exclusive keys needed by particular files.

Recover supported customer files and associated catalogue information locally. Your downloaded archive has its own retention; the hosted recovery window is 14 days.

Encryption icon
Client-side encryption

Messages and files are encrypted before upload, reducing readable-data exposure inside vendor infrastructure.

Separation icon
Organisation separation

Identity-based access and organisation security boundaries keep each tenant’s users and content separated within the hosted service.

Audit icon
Access, audit and provenance

Controlled external access, audit context and cryptographic provenance help teams verify the recorded sender identity and whether a document changed.

Threat model

What We Secure Data is designed to reduce.

Designed to protect against
  • Vendor breach exposing readable customer data.

  • Unauthorised direct access to encrypted content in storage.

  • SaaS central breach target risk.

  • Storage compromise where attackers obtain encrypted blobs only.

Not designed to replace
  • Endpoint security for compromised user devices.

  • Strong identity controls for stolen user credentials.

  • Good internal access governance, approvals, and user lifecycle management.

Implementation-backed cryptography

Browser encryption and independently reproducible evidence checks.

Files use AES-256-GCM with fresh per-file data-encryption keys, authenticated chunk metadata and KMS key wrapping. Separate ECDSA P-256 keys sign canonical provenance evidence and public audit anchors.

A trusted public key must first be obtained from the authenticated We Secure Data key endpoint or another trusted source.

LAYERED BUSINESS SECURITY

Protect access. Check the evidence.

Encryption protects confidentiality. Access controls limit who can retrieve protected content. Cryptographic provenance lets a recipient check signed content and recorded origin. Together, these controls give your team confidentiality, controlled access and checkable evidence of what was shared.

Separate deployment model

We Secure Data Dedicated Deployment

Need your own infrastructure?

Organisations that want their own environment can purchase a turnkey dedicated deployment. We Secure Data prepares the agreed environment, ready for the customer to take ownership. The scope can include dedicated infrastructure, customer-controlled KMS and IAM, and an organisation-specific domain and branding.

This is a premium alternative to SaaS, not a prerequisite for using We Secure Data.

Different controls solve different problems.

Recipient access checks control retrieval; retraction withdraws future external access. Encryption protects content. Provenance checks recorded origin and file integrity. Hosted permission scoping and a separately provisioned dedicated environment are different isolation arrangements. These measures support your policies; they are not a guarantee against all fraud or a compliance certification.
