About We Secure Data

Secure communication you can prove

Businesses already have ways to send messages and files securely. The missing layer is proof. WSD combines secure communication with cryptographic provenance, creating independently verifiable evidence of origin and integrity.

A different starting point

From trust to proof

Traditional communication systems answer: Can this information be sent securely?

WSD also asks: Can we prove where it came from and that it is unchanged?

Screenshots, email headers, audit logs and provider records can all be useful. But they can leave organisations dependent on a system or service provider explaining what happened. WSD was designed to attach cryptographic evidence to the protected communication itself.

OriginWhere did it come from?
SenderWho sent or created it?
IntegrityHas the content changed?
EvidenceCan it be verified independently?
Two complementary protections

Protect the content. Prove the content.

01

Confidentiality

Encryption and controlled recipient access help keep sensitive information private and limit who can read it.

02

Provenance

Cryptographic evidence helps establish origin and integrity, so protected content can be checked rather than simply accepted.

WSD brings both together in one communication platform.

Hosted WSD SaaS

Enterprise-grade verifiable communication without enterprise deployment

Why it matters

Important communication can be challenged later

When authenticity matters, a defensible record is more useful than another assertion.

Security architecture

Security designed into the communication

Hosted WSD combines client-side encryption, controlled recipient access, organisational separation and cryptographic provenance. These layers protect access to sensitive information while creating evidence about its source and integrity.

The architecture supports secure communication without requiring customers to configure their own infrastructure.

Our mission

To make important digital communication verifiable

To give organisations more than a secure delivery channel—to give them cryptographic evidence they can retain and independently verify.

Move from “trust that this is genuine” to “prove that this is genuine.”

Don't just secure what you send. Prove it.

WSD combines secure communication with cryptographic provenance and independently verifiable evidence.
